Welcome everyone to PV solar energy course since the last lecture 1
We've already finished their first type which is crystalline silicon. 2
Today we are going to move on the next type which is thin film solar cell TFSC. 3
you're posting one or several thin layers of photovoltaic material onto a subst is 4
the basic gist of how is a thin film solar cell are manufactured. 5
They are also known as sinful photovoltaic. 6
The different types of sin film solar cells can be categorized or photovoltaic material depositing onto 7
a Z substrate first amorphous silicon second cadmium telluride said carbon indium gallium Illinois. 8
It's the largest one is Organic Photovoltaics similar 9
depending on the technology. 10
The send fan module or prototypes have is the efficiencies between seven to 16 percent which is lower 11
Zen said Chris. 12
The line cynical as the production modules operate at about 9 per cent future module efficiencies are 13
expected to climb close to 10 and 16 percent. 14
The market for Seinfeld grow excuse 2 percent annual rate from 2002 to 2000 and 7 into an eleven close 15
to five percent of U.S. photovoltaic module shipments to residential sector. 16
We are based on Seinfeld so what is the main advantage of sinful. 17
First the mass production is simple. 18
This makes them potentially cheaper to manufacture Zen Ze crystalline based so lets the second sink 19
zero homogeneous appearance make them look more desirable can be made flexible which open up many new 20
potential application high temperature and cheating has less impact on solar than on performance in 21
a situation where just this is not the issue. 22
Sin firm solar burner can make seen but see this advantage of sin thin as the thin film solar panel 23
are generally not very useful for most residential situation. 24
They are sheep but they also require a lot of space so some power companies monitor crystalline solar 25
panel reduce up to four times the amount of electricity as thin film solar panels for the same amount 26
of space. 27
Lower space efficiency also means that the cost of B V equipment will increase such as cable support 28
destruction and so on. 29
Since then solar has been on the fence to degrade faster than the model and the poly crystalline out. 30
Which is why typically come with a shorter warranty. 31
Solar panel based on amorphous and cadmium to the right and the cover indium gallium solenoid are currently 32
the only cell phone and technologies that are commercially available in this market. 33
So let's start with amorphous silicon or it is oil because out of that electrical power is low the solar 34
cell based on amorphous silicon had traditionally only been used for a small scale application such 35
as in public escalator. 36
However there is an innovation have made them more attractive for some large scale application to 37
with a manufacturing technique called is taking several layers of amorphous silicon solar cells can 38
be combined which resulted in the higher efficiency rates digitally around 6 and 8 percent 39
but only one third percent of the silicon use they increase the Lions silicone solar cell is wired in 40
amorphous and it goes solar cell. 41
On the other hand says taking is very expensive 42
let's just start with the second type is cadmium to the right solar cell. 43
C D T E guiding them to the right is the only film analogy that has to base is of course the efficiency 44
of their crystallized silicon solar panel is a significant portion of the market which is hard to keep 45
and what system. 46
Say efficiency of solar panel on the cadmium telluride usually put it in the range between 9 to 11 percent. 47
First Solar has installed over 5 gigawatts of garden room to load points and then solar Bennett the 48
way up the same company halls. 49
So while the record for government to the right module efficiencies of fourteen point four per cent 50
so lost by Escobar India got you there like 51
compared to other Centennial technologies above sea org. 52
Yes. 53
Solar cells have showed the most attention in terms of the efficiency. 54
This solar said going the least amount of the toxic material cadmium that is found in C DTC solar cell 55
commercial production of flexible C. 56
Oh yes. 57
The solar panel was started in Germany into any eleven their efficiency rate for C. 58
Oh yes. 59
Solar Benin is typically operate in the range of 10 to 12 percent many send film solar cell types are 60
still early in their research and did this thing to stage some of them have enormous potential and will 61
likely see more of them in the future. 62
So let's think in this section we are going to give you Z me comparison between the thin film solar 63
panel and crystalline silicon solar panel let's go inside so types of technology further science cynical 64
can be mainly divided into one to cross the line and fully cross the line. 65
Then another type which is all drink arriba but is not widely used. 66
The same NFL can be divided into four categories. 67
First category is called indium garden Silverlight. 68
That second category is organic photovoltaic cell sir. 69
The category is amorphous silicon which is widely used. 70
Zoll last category is cadmium. 71
Tim Roy as you see the copper indium gallium solenoid is the most used type 72
crystalline silicone solid metal has alters rating between 80 to 85 percent on the other hand. 73
The seventy two to seventy eight per cent for a synthetic note high end of the circuit and maximum four 74
point voltage is much better for the solar panel 75
set in Britain coefficient for crystalline sentiment is higher but it's much lower for does it centre 76
means in high temperature places. 77
We need Syn to not crystalline Senate so I V Kanter fell factor is vintage three to eighty two percent 78
for others the lion citizen but suggested per sent to the sixty eight percent for central module construction 79
workers the lines typical it will be with those elements but in some form it could be friendlies send 80
the which between the losses lower cost and lower weight when we are going to efficiency the efficiency 81
in crystalline silicon is much higher it's between 17 to 19 percent but in case of Seinfeld it's between 82
4 and twelve percent 83
so we can summarize that if you are at home place you should use Seinfeld money and if you had a less 84
the space you usually use to lie in Senegal but if the space is not a problem for you but sitting preacher 85
and power is the main problem for you so try to use and and it would be better for you now in this fiction 86
you already see the different types of 18 modules it is a make a section we are going to put this ties 87
together to build for a solar array see you in the next section.
