With borders thin-film solar battery components

Product Description:

Amorphous silicon is currently the world's most popular film technology, with thin film battery materials, low cost, low energy consumption, less common characteristics of zero pollution, convenient installation, and it compared with the traditional crystalline silicon has the following advantages:

Low amorphous silicon solar cells per watt average annual capacity is higher than crystalline silicon 10% to 15%

There are two main reasons:

1, amorphous silicon thin film solar cell than monocrystalline silicon, polycrystalline silicon cells have relatively small temperature coefficient, amorphous silicon thin film solar cell output power best temperature coefficient is about 0.2%, and the single crystal silicon, polysilicon batteries battery best temperature coefficient of output power is about 0.5%, solar battery under the sun, its junction temperature will rise rapidly, two kinds of battery maximum power output will decline, work under 50 ℃, 60 ℃, the amorphous silicon battery power is about 10% more than crystalline silicon cells and the higher the working temperature, the greater the gap.

2, amorphous silicon has good weak light of the sun requires the widest range of incident Angle, the scattering light acceptance rate is high, and the dust weather in rainy weather can still continue to work, this determines the amorphous silicon in average effective sunshine time is longer than crystalline silicon cells.

\"Hot spot effect is not obvious

When the solar cell array area is larger, hard to avoid can have some components in the shadows, because the current density of amorphous silicon thin film solar cell is small, hot spot effect is not obvious, so, use rise more convenient and reliable.

\"Beautiful, generous

When the battery components installed on the roof and walls:

1, save expensive outside decoration materials (glass curtain wall, etc.), reducing the structure of the overall cost;

2, direct absorption solar power;

3, avoid walls, the roof temperature is too high, reduces the air conditioning load;
