sticker problem it it was a give away from phone one of
00:00:06
the first pro checked on organic fort walton likes which uh
00:00:10
in the beginning of this that was a big bone everybody's sort
00:00:14
uh oregon affordable tight will solve a lot of problems which other um
00:00:19
p. v. technology says but i think this was six years ago but today i think we are big step further and my
00:00:26
compared to my uh u. s. b. stick the demonstrator
00:00:30
on o. p. v. still works off to six years
00:00:35
okay so make mikhail and people talk today on a on a real product of a coloured
00:00:41
which to conduct for trouble tyke modules which is between two awesome class i maybe we'll talk about
00:00:48
uh environmental aspects and mikhail at maybe we'll talk
00:00:51
about um the the sign aspects which are really pleasant
00:01:00
so the challenge was switzerland is uh that uh it until two thousand fifty
00:01:06
the uh share or for to what tyke showing trees for up to twenty percent
00:01:12
and it can be only achieves twenty be considered b. p. b. s. o. opportunity
00:01:19
but as we already heard in several presentations today b. p. v. um
00:01:24
have a big problem we do want not want to have black cities
00:01:29
so coloured coloured to um b. p. b. is would be a
00:01:33
solution but we have a big problems we have yield losses so
00:01:42
maybe the first look a bit on how our model looks like it's it's really one
00:01:46
of the the sign be if seen in the past presentation we have a glass class module
00:01:52
uh uh which inc which is think cups relation
00:01:56
of uh of silicone modules and we have inside
00:02:01
of the gloss of the out of front claws we have the printed collar
00:02:06
before we talk on environmental aspects you really want to come to the pleasant part of this product
00:02:13
uh which is the the sign and this will be explained by mikhail
00:02:21
thank you very much here okay
00:02:26
for all the fourth one night even design project is located
00:02:31
i hate quarter of we just do the things are demon
00:02:38
of the three stooges and it turned into conduct p. v. modules
00:02:43
let's take a look at in fact we created sixty to
00:02:47
tell fair are printed and laminated glass glass not use each of
00:02:52
size two hundred thirty five fifty five centimetres print it and
00:02:57
setting it class which means there is no reflection to the surrounding
00:03:03
oh that s. r. nominate one of crystal in active buyer
00:03:07
sells forty two cents each module which use which owes earth tone
00:03:14
colour sleeker relative efficiency of seventy five the themes
00:03:19
for each e. consist of a greek contests on
00:03:23
the front face and a greek p. there on
00:03:25
the back these days isn't metal construction on concrete foundation
00:03:34
oh the premise is i don lake replaced my steely at the entrance of the property
00:03:41
and tuesday it's near by the weather
00:03:51
each of the p. module it's face in another direction for all nice disability
00:03:58
can somebody should write it on it which might parties
00:04:05
yeah okay interesting okay um replacements the here and in truth
00:04:12
in one and play two things here near by the water
00:04:18
three two and three and each of them what was his face in another direction
00:04:24
the placement of this these weren't given at the placement of
00:04:28
this these are planned ascii art in the garden like sculptures
00:04:34
the morning talking ah show was actually they accumulate output of the stick separately murders
00:04:41
all the six p. v. modules are labelled as the number
00:04:46
and the in so we can get a good information on each little
00:04:53
this these they're just in style
00:05:00
something that's of thank yous colours we selected a set of subdued colour tones
00:05:08
the selected on two and a half tone colours
00:05:11
are suitable for aesthetic appeal to deploy in building assets
00:05:17
different colours equally different print capacities for the same resell of electric efficiency
00:05:25
the efficiency last of the selected colour sex or tested through
00:05:30
c. s. u. n. issue there i say steak external control efficiency
00:05:35
we chose setting a class i set a thirty if to reduce the tension and their effects
00:05:43
the effect of samples
00:05:47
which we perform thank you mentioned on
00:05:52
nobody's diffuse appearance of this actually native bath
00:06:01
here we see one of the leaves injury prank in three
00:06:04
prints entities in terms only an actor nomination with keeping module
00:06:13
this enables us to assess the perceived colours
00:06:16
and how these are impacted by separate entities
00:06:21
take into account that that relative efficiencies based upon the print density we
00:06:28
liked it that twenty he couldn't or for posting is that a true
00:06:36
right at lake and forty p. p. could database the that intense
00:06:43
feel free to e. aspect booths number thirteen very yeah i
00:06:46
see add different colour t. v. samples on display thank you
00:06:54
hi
00:06:58
hi would like now to continue is a vista asides from a life cycle assessment
00:07:04
on these uh b. p. v. modules which i've presented in the beginning
00:07:10
as you can see i'm a i'm the if you look on this on this graph you see
00:07:15
the impacts of the components of such a such
00:07:18
a models the beginning risotto maybe the additional glossy require
00:07:23
uh to make such a module and the printing may have a relevant impact
00:07:28
but if you look on the wrist side here now you can see that uh really the main the main impacts
00:07:34
comes from the from the cells so the uh move
00:07:37
to crystal in silicon cells into a single crystalline silicon cells
00:07:42
so the first results uh we can uh we have achieved you can say
00:07:47
the class the addition plus amount will require compared to rooftop
00:07:52
of solar cells no solar modules must have a plastic back she'd
00:07:57
uh up and the the printing is not can be
00:08:00
negated by the way the impact here is calculated by
00:08:03
us with specific environmental impact indicator which considers all different
00:08:09
impact categories not only climate changes well the impact from uh
00:08:13
pacific asian or from from da store from nuclear radiation and so on
00:08:24
but i mean i'm be need much more than a panel to produce electricity
00:08:28
and at the end it's interesting to know what is the impact of the
00:08:32
electricity uh of such at b. u. b. i. p. v. for say discover modules
00:08:38
so and this cross here you see again uh we have two
00:08:43
types of models you have the will to move to crystal in
00:08:48
s. sequence else would be coloured and the single a crystalline
00:08:53
silicon cells as well here see even on the level of
00:08:57
of uh of uh of the t. v. for sake
00:09:00
we see the cells are the main driver for the impact
00:09:05
and single cell single crystalline cells it's even have
00:09:09
a higher impact reuse latest published data for this
00:09:12
uh for this life cycle assessment and um so um i think there's on to today there's not
00:09:20
not much uh much progress achieved to reduce the environmental impact in production
00:09:28
what is interesting to see here as well sorry um
00:09:34
oh i know what kind of john
00:09:38
not a curious um what you can see here as as well
00:09:44
we have several other components here such as the
00:09:48
uh electric compounds the inverted and the electric installations
00:09:51
which have a maybe a share of about twenty percent and we have the um mountain system here
00:09:59
and um of course it can be said if the uh the
00:10:05
solar panels are integrated part of a building
00:10:11
such is the case of replacement of uh arrange lighting system we can be said that the the glass
00:10:17
and the mounting system can be alike are located to the buildings we'll fix this is that kind of uh
00:10:22
um prove methodology to to reduce the
00:10:27
impact of to put a generated electricity
00:10:31
so that in fact would be about twenty per if we apply
00:10:34
this metallurgy we can can reduce the impact by about twenty percent
00:10:41
interesting now is really to see how uh the impact of to generate electricity
00:10:46
in this chart we just focus on this you to impact which
00:10:49
is uh uh i think the most interesting for most of the people
00:10:55
and you see here the orientation off this solar panel this
00:10:59
a jungle off lines here are different for a configurations which have assessed that means we have a system
00:11:05
will to crystal into single crystal lean colour not
00:11:08
coloured um the rain clothing but replacement and so one
00:11:15
and as well you see two lines here this is
00:11:18
the uh average a greenhouse gas impact from swiss electricity
00:11:23
this is about one hundred sixty grams due to high share of nuclear and hydropower but as well of the
00:11:29
european electricity bakes which as of about four hundred fifty grams per generate
00:11:35
the tequila what our electricity can be
00:11:38
set in the european context mainly or configurations
00:11:43
have a a greenhouse gas benefit but if you just focus on on swiss
00:11:48
t. on on sweets when we was of which was the focus in this study
00:11:52
we cannot say that all configurations or or orientations really
00:11:56
we really would use green energy is must be considered
00:12:01
another point which people like to note is the end it should pay back to a
00:12:06
so what we can see here in that what we have here is the total energy
00:12:11
which really required as the indebted energy of the production of a module
00:12:16
orifice eight and here we have the the lifetime of the years what you see here
00:12:22
this is uh the the grey and that she off to space electricity makes
00:12:28
i'm just regarding non renewable energy so it in
00:12:31
fact is is the nuclear energy part and by the
00:12:36
years you produce more more energy and we if either divide this by the initial
00:12:41
uh in that should be required to produce the modules becomes to a specific energy
00:12:47
which is after f. eight years for that
00:12:50
type of um what was this solves orientation
00:12:55
oh this is the slightest thousand would decrease barely moved because other modules we have a achieved
00:13:02
um produce it get more energy than we have it and invest it
00:13:08
it was surprising to hear me in a former presentations that uh in singapore they have several
00:13:13
have similar results maybe it's to to do two
00:13:16
more tossed layers on on uh on the models
00:13:22
so it can be summarised that not in under all conditions b. p. v. modules
00:13:28
are environmentally beneficial but as in particular
00:13:32
to south and southeast orientation it's fine
00:13:35
um with the crystal in is fine crystal in b. c. a bit critical but
00:13:39
of course you future the in uh the the progress deficiency will increase of the modules
00:13:45
and as well the production of the cells the impact
00:13:48
will use to more uh if you should do more efficiency
00:13:53
um in this project several actors were involved so the the
00:13:58
sign was they've developed by the university of applied science you loser
00:14:03
the glass suppliers trish the module was produced
00:14:06
by g. s. i. c. specification was done by
00:14:10
the university sweets applied switzerland so a sign since it's been in in in content this scene
00:14:18
who have had organisations off uh the testing
00:14:21
procedure and finally the license holder of this product
00:14:24
is user was which is a spin off of um of the university of applied science closer
00:14:32
there are some certificate kate's you see a lot of to do to get such a product on the market one
00:14:37
circuit certification still on the on the rate it's about
00:14:40
the environmental impact and yes we did as well some publications
00:14:46
and finally we would we would conclude that um the environmental bernard
00:14:52
acceptable offs of a card with the call that b. p. ways
00:14:57
um the the product tests ever has survived several certification tests
00:15:03
and uh the the sign opportunities are great too for architect
00:15:09
architects it yeah and he would like to another which uh the project
00:15:13
partners and as well the project
00:15:16
a founding thank you very much ha
