When the sunlight enters into P/N junction, electric power is
directly generated by semiconductor effect.
Manufacturers of PV cell / module are struggling;
1. to reduce the amount of silicon material to be consumed,
2. to increase the conversion efficiency of PV cell / module, and
3. to reduce the production cost.

The output of the PV system is basically unstable because it
varies depending on the weather, but connecting with the grid
makes it possible to constantly supply power to consumers.

Monocrystal
Monocrystal about 200 microns thick is used as the substrate.
Crystal
The conversion efficiency and reliability are high, but the price is high as well.
Up to 20%
Polycrystal consisting of relatively small crystals is used as the substrate.
Silicon
Polycrystal
Compared with the monocrystal type, this is easy to manufacture and inexpensive, but the
Up to 15%
efficiency is low.
Thin-film
This type is made by forming an amorphous or crystalline silicon film (about 1 micron thick) on
a glass substrate. The efficiency is lower than that of the crystalline silicon type.
Up to 9%
This is a thin-film PV cell made from copper, indium, and selenium.
CIS
The CIS type features resource saving and mass production, and is expected to have high
Up to 12%
performance.
Compound
CdTe
This is a thin-film PV cell made from cadmium and tellurium.
The CdTe type features resource saving, mass production, and low price.
Up to 11%
This type is given by applying multiple junctions and condensing technologies to a compound
Condenser
consisting of group-III and group-V elements.
Up to 42%
The performance is high but the price is high.
Dye sensitizer
Organic
Organic thin-film
Dye adhering to titanium oxide absorbs light and generates power.
Up to 11%
The dye sensitizer type is in the R&D stage.
(Expected)
This type is made by coating a film using an organic semiconductor.
The organic thin-film is in the R&D stage.

Regulation of Japanese Power Industry (1)
March 2, 2014
(a) Electricity Business Act regulates the power industry, and safety of
power facilities and equipment.
NPDCL
(b) Ministry of Economy, Trade and Industry, Agency for Natural Resources
and Energy is in charge of this act and regulates the industry through
implementation rules and regulations based on the act.
(c) Power supply has been deregulated over the past decade, and liberalized
up to large customers.
(d) East Japan Great Earth Quack and Tsunami on March 11 2011, and
the following nuclear disaster of Fukushima Nuclear Power Station I has
required significant change in the regulatory framework and method.
Ministry of Economy, Trade and Industry has been repealed of authority
to regulate nuclear power industry, which is now under Ministry of
Environment.

NPDCL
(1) In April 2013 the bill for the act for partially revision of Electricity
Business Act was approved by the cabinet and was submitted to the
diet. The purpose of the bill is to create an independent institution
that operates national power system by 2015 in stead of 10 power
companies.
(2) Further, power supply to general household will be liberalized by 2016.
Retail sales of electricity will be completely liberalized.
(3) Between 2018 and 2020, unbundling between power generation and
transmission is planned.

21. ROUGH ESTIMATION OF PV GENERATION
NPDCL
If a 10kW system, for example, is installed in Tokyo
with the array having an optimal tilt angle and
pointing south, then the annual energy generation
is given as follows:
10 (kW) 3.92 (kWh/m2鐔day) 0.7 365 (days) =
10,016 (kWh/year)
In case of India
10X6X.7X365=15330(Kwh/year)
March 2, 2014
Ep=PAS * HA * K * 365 days
Ep = Expected annual energy (kWh/year)
PAS = Rated capacity of PV array (kW)
HA = Daily irradiation on yearly average
(kWh/m2/day)
K = Total design factor (0.65 to 0.8 or about 0.7 in
average)
21
22. ROUGH ESTIMATION OF REQUIRED AREA
March 2, 2014
NPDCL
Sunlight has energy 1KW/ m2 after it reaches the
ground through space and atmosphere.
If PV cell conversion efficiency 15%
1KWX.15=.15KW because the conversion efficiency
of crystalline silicon cell is about 15%.This means
that a power of 1KW requires an area about 6.6
m2. The thin film type can conversion efficiency is
8% so that the required area is about 12.5 m2 .In
actual installation, a power of 1KW requires 10-15
m2 for maintenance space between PV arrays
Conclusion :Area depends upon the conversion
efficiency
