Technical advantages

1. Good weak light performance:

Ideally, output power of solar module should be the direct portion of the intensity of sunlight. And thin film silicon solar cell has such characteristic, however crystalline don’t. With a situation of sunlight of 200 watt per square meter, output power of crystalline solar module is around 85% of it should be. That means solar power system with crystalline solar module will not generate power in the late afternoon. However, solar power system with thin film silicon solar cell still generates power. The performance of thin film silicon solar cell is better than that of crystalline solar cell in the weak light condition. Normally, installed module worked in a strong light of 1000 watt per square meter is very few.

Furthermore, thin film silicon has gentle current-voltage curve. This characteristic makes it easier to pick-up the most electricity power

2.Low temperature coefficient:

The temperature of solar module, which installed at the roof of building, can be even higher. It is not unusual for the temperature of solar module to achieve 550c. In this case, the temperature coefficient is a very important parameter due to various solar cell technology. The temperature coefficient is always minus. With the temperature increase, module power will decrease accordingly. Temperature coefficient for thin film silicon solar cell is -0.2%/0c, and that of crystalline solar cell is -0.5%/0c. That means, when the module is worked on 500c condition, compare to the efficiency reached on 250c test standard , thin film silicon solar module will loose around 5%, and the loss for crystalline will be around 12.5%. Normally, the electricity performance of photovoltaic module is measured by STC standard. Which include strong sunlight(1000 W sunlight per square meter,1.5 A solar spectrum distributing) and 250c solar cell temperature. However, the temperature of solar module, operating in the sun, can be higher than atmosphere temperature 280c.

In conclusion, even the STC efficiency of thin film silicon solar cell is low, the efficiency in actual operation condition is not far away to that of crystalline solar cell.
