Welcome everyone to PV solar energy course since the last lecture
1

2
00:00:12,060 --> 00:00:17,950
We've already finished their first type which is crystalline silicon.
2

3
00:00:18,130 --> 00:00:24,680
Today we are going to move on the next type which is thin film solar cell TFSC.
3

4
00:00:24,710 --> 00:00:34,410
you're posting one or several thin layers of photovoltaic material onto a subst is
4

5
00:00:34,410 --> 00:00:39,950
the basic gist of how is a thin film solar cell are manufactured.
5

6
00:00:40,500 --> 00:00:45,870
They are also known as sinful photovoltaic.
6

7
00:00:47,450 --> 00:00:57,660
The different types of sin film solar cells can be categorized or photovoltaic material depositing onto
7

8
00:00:57,660 --> 00:01:10,280
a Z substrate first amorphous silicon second cadmium telluride said carbon indium gallium Illinois.
8

9
00:01:10,730 --> 00:01:14,020
It's the largest one is Organic Photovoltaics similar
9

10
00:01:17,220 --> 00:01:19,470
depending on the technology.
10

11
00:01:19,470 --> 00:01:28,800
The send fan module or prototypes have is the efficiencies between seven to 16 percent which is lower
11

12
00:01:28,800 --> 00:01:30,300
Zen said Chris.
12

13
00:01:30,470 --> 00:01:42,410
The line cynical as the production modules operate at about 9 per cent future module efficiencies are
13

14
00:01:42,500 --> 00:01:48,600
expected to climb close to 10 and 16 percent.
14

15
00:01:48,890 --> 00:02:02,530
The market for Seinfeld grow excuse 2 percent annual rate from 2002 to 2000 and 7 into an eleven close
15

16
00:02:02,560 --> 00:02:08,870
to five percent of U.S. photovoltaic module shipments to residential sector.
16

17
00:02:08,910 --> 00:02:17,090
We are based on Seinfeld so what is the main advantage of sinful.
17

18
00:02:17,330 --> 00:02:20,510
First the mass production is simple.
18

19
00:02:20,510 --> 00:02:28,610
This makes them potentially cheaper to manufacture Zen Ze crystalline based so lets the second sink
19

20
00:02:28,860 --> 00:02:38,840
zero homogeneous appearance make them look more desirable can be made flexible which open up many new
20

21
00:02:38,840 --> 00:02:47,630
potential application high temperature and cheating has less impact on solar than on performance in
21

22
00:02:47,640 --> 00:02:51,020
a situation where just this is not the issue.
22

23
00:02:51,030 --> 00:03:02,170
Sin firm solar burner can make seen but see this advantage of sin thin as the thin film solar panel
23

24
00:03:02,510 --> 00:03:08,550
are generally not very useful for most residential situation.
24

25
00:03:08,660 --> 00:03:18,470
They are sheep but they also require a lot of space so some power companies monitor crystalline solar
25

26
00:03:18,650 --> 00:03:26,810
panel reduce up to four times the amount of electricity as thin film solar panels for the same amount
26

27
00:03:26,810 --> 00:03:27,720
of space.
27

28
00:03:29,950 --> 00:03:39,490
Lower space efficiency also means that the cost of B V equipment will increase such as cable support
28

29
00:03:39,500 --> 00:03:41,930
destruction and so on.
29

30
00:03:44,410 --> 00:03:51,490
Since then solar has been on the fence to degrade faster than the model and the poly crystalline out.
30

31
00:03:51,550 --> 00:03:56,110
Which is why typically come with a shorter warranty.
31

32
00:04:00,240 --> 00:04:09,180
Solar panel based on amorphous and cadmium to the right and the cover indium gallium solenoid are currently
32

33
00:04:09,330 --> 00:04:15,030
the only cell phone and technologies that are commercially available in this market.
33

34
00:04:15,090 --> 00:04:27,340
So let's start with amorphous silicon or it is oil because out of that electrical power is low the solar
34

35
00:04:27,340 --> 00:04:35,710
cell based on amorphous silicon had traditionally only been used for a small scale application such
35

36
00:04:35,860 --> 00:04:38,080
as in public escalator.
36

37
00:04:38,860 --> 00:04:47,530
However there is an innovation have made them more attractive for some large scale application to
37

38
00:04:50,530 --> 00:04:59,020
with a manufacturing technique called is taking several layers of amorphous silicon solar cells can
38

39
00:04:59,020 --> 00:05:07,810
be combined which resulted in the higher efficiency rates digitally around 6 and 8 percent
39

40
00:05:10,580 --> 00:05:17,810
but only one third percent of the silicon use they increase the Lions silicone solar cell is wired in
40

41
00:05:17,870 --> 00:05:21,590
amorphous and it goes solar cell.
41

42
00:05:21,670 --> 00:05:25,560
On the other hand says taking is very expensive
42

43
00:05:29,170 --> 00:05:35,140
let's just start with the second type is cadmium to the right solar cell.
43

44
00:05:35,290 --> 00:05:44,540
C D T E guiding them to the right is the only film analogy that has to base is of course the efficiency
44

45
00:05:44,630 --> 00:05:51,800
of their crystallized silicon solar panel is a significant portion of the market which is hard to keep
45

46
00:05:51,800 --> 00:05:53,030
and what system.
46

47
00:05:53,270 --> 00:06:01,880
Say efficiency of solar panel on the cadmium telluride usually put it in the range between 9 to 11 percent.
47

48
00:06:01,970 --> 00:06:10,110
First Solar has installed over 5 gigawatts of garden room to load points and then solar Bennett the
48

49
00:06:10,140 --> 00:06:13,100
way up the same company halls.
49

50
00:06:13,100 --> 00:06:20,360
So while the record for government to the right module efficiencies of fourteen point four per cent
50

51
00:06:22,760 --> 00:06:26,860
so lost by Escobar India got you there like
51

52
00:06:30,150 --> 00:06:34,420
compared to other Centennial technologies above sea org.
52

53
00:06:34,500 --> 00:06:34,980
Yes.
53

54
00:06:35,050 --> 00:06:41,040
Solar cells have showed the most attention in terms of the efficiency.
54

55
00:06:41,160 --> 00:06:50,970
This solar said going the least amount of the toxic material cadmium that is found in C DTC solar cell
55

56
00:06:52,690 --> 00:06:55,250
commercial production of flexible C.
56

57
00:06:55,260 --> 00:06:56,330
Oh yes.
57

58
00:06:56,440 --> 00:07:04,010
The solar panel was started in Germany into any eleven their efficiency rate for C.
58

59
00:07:04,040 --> 00:07:05,310
Oh yes.
59

60
00:07:05,600 --> 00:07:15,500
Solar Benin is typically operate in the range of 10 to 12 percent many send film solar cell types are
60

61
00:07:15,500 --> 00:07:22,970
still early in their research and did this thing to stage some of them have enormous potential and will
61

62
00:07:23,060 --> 00:07:26,240
likely see more of them in the future.
62

63
00:07:28,610 --> 00:07:37,370
So let's think in this section we are going to give you Z me comparison between the thin film solar
63

64
00:07:37,370 --> 00:07:49,600
panel and crystalline silicon solar panel let's go inside so types of technology further science cynical
64

65
00:07:49,930 --> 00:07:55,600
can be mainly divided into one to cross the line and fully cross the line.
65

66
00:07:56,010 --> 00:08:02,530
Then another type which is all drink arriba but is not widely used.
66

67
00:08:04,770 --> 00:08:09,570
The same NFL can be divided into four categories.
67

68
00:08:09,680 --> 00:08:14,290
First category is called indium garden Silverlight.
68

69
00:08:14,390 --> 00:08:20,540
That second category is organic photovoltaic cell sir.
69

70
00:08:20,570 --> 00:08:24,940
The category is amorphous silicon which is widely used.
70

71
00:08:25,810 --> 00:08:29,010
Zoll last category is cadmium.
71

72
00:08:29,050 --> 00:08:35,940
Tim Roy as you see the copper indium gallium solenoid is the most used type
72

73
00:08:39,190 --> 00:08:50,850
crystalline silicone solid metal has alters rating between 80 to 85 percent on the other hand.
73

74
00:08:50,930 --> 00:09:01,680
The seventy two to seventy eight per cent for a synthetic note high end of the circuit and maximum four
74

75
00:09:01,800 --> 00:09:06,240
point voltage is much better for the solar panel
75

76
00:09:10,040 --> 00:09:17,260
set in Britain coefficient for crystalline sentiment is higher but it's much lower for does it centre
76

77
00:09:17,710 --> 00:09:21,850
means in high temperature places.
77

78
00:09:21,850 --> 00:09:32,670
We need Syn to not crystalline Senate so I V Kanter fell factor is vintage three to eighty two percent
78

79
00:09:32,880 --> 00:09:41,450
for others the lion citizen but suggested per sent to the sixty eight percent for central module construction
79

80
00:09:41,630 --> 00:09:50,610
workers the lines typical it will be with those elements but in some form it could be friendlies send
80

81
00:09:50,710 --> 00:10:01,660
the which between the losses lower cost and lower weight when we are going to efficiency the efficiency
81

82
00:10:01,660 --> 00:10:13,840
in crystalline silicon is much higher it's between 17 to 19 percent but in case of Seinfeld it's between
82

83
00:10:14,200 --> 00:10:15,790
4 and twelve percent
83

84
00:10:18,670 --> 00:10:29,870
so we can summarize that if you are at home place you should use Seinfeld money and if you had a less
84

85
00:10:29,870 --> 00:10:39,670
the space you usually use to lie in Senegal but if the space is not a problem for you but sitting preacher
85

86
00:10:39,670 --> 00:10:49,690
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

87
00:10:50,140 --> 00:10:58,600
you already see the different types of 18 modules it is a make a section we are going to put this ties
87

88
00:10:58,780 --> 00:11:06,540
together to build for a solar array see you in the next section.
