Electron
P- type Silicon
When the sunlight enters into P/N junction, electric power isdirectly 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, and3. to reduce the production cost.

The output of the PV system is basically unstable because itvaries depending on the weather, but connecting with the gridmakes it possible to constantly supply power to consumers.
Classification of PV cellsModule’s
Type Photo Features conversion
efficiency
MonocrystalMonocrystal about 200 microns thick is used as the substrate.
The conversion efficiency and reliability are high, but the price is high as well.
Polycrystal consisting of relatively small crystals is used as the substrate.
Polycrystal Compared with the monocrystal type, this is easy to manufacture and inexpensive, but the
efficiency is low.
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.
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
performance.
This is a thin-film PV cell made from cadmium and tellurium.
The CdTe type features resource saving, mass production, and low price.
This type is given by applying multiple junctions and condensing technologies to a compound
Condenser consisting of group-III and group-V elements.
The performance is high but the price is high.
Dye adhering to titanium oxide absorbs light and generates power.
The dye sensitizer type is in the R&D stage.
This type is made by coating a film using an organic semiconductor.
The organic thin-film is in the R&D stage.

Country Report of Japan (5)Regulation of Japanese Power Industry (1)
(a) Electricity Business Act regulates the power industry, and safety ofpower facilities and equipment.
(b) Ministry of Economy, Trade and Industry, Agency for Natural Resourcesand Energy is in charge of this act and regulates the industry throughimplementation rules and regulations based on the act.
(c) Power supply has been deregulated over the past decade, and liberalizedup to large customers.
(d) East Japan Great Earth Quack and Tsunami on March 11 2011, andthe following nuclear disaster of Fukushima Nuclear Power Station I hasrequired significant change in the regulatory framework and method.Ministry of Economy, Trade and Industry has been repealed of authorityto regulate nuclear power industry, which is now under Ministry ofEnvironment.

Regulation of Japanese Power Industry
(1) In April 2013 the bill for the act for partially revision of ElectricityBusiness Act was approved by the cabinet and was submitted to thediet. The purpose of the bill is to create an independent institutionthat operates national power system by 2015 in stead of 10 powercompanies.
(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 andtransmission is planned.

ROUGH ESTIMATION OF PV GENERATION
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)
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 ・ day) × 0.7 × 365 (days) = 10,016 (kWh/year)
In case of India 10X6X.7X365=15330(Kwh/year)

ROUGH ESTIMATION OF REQUIRED AREA
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
