Amorphous silicon thin film solar cells product line

Specification

1 .Advantages of amorphous silicon solar cell:

1. Low manufacturing cost:

  • Amorphous silicon thin film solar cells only need a few microns of semi-conducting materials but the crystalline silicon solar cells need 200-300 microns of semi-conducting materials, amorphous silicon thin film solar cells just consume about 1/100,it save a lot of silicon materials.

  • PIN junction of amorphous silicon thin film solar cells is made in the 200℃,itís much lower than the crystalline silicon solar cells which is made under 800℃~1000℃ high temperature and save a lot of energy.

  • We apply integrated technology and the cells are completed during production ,the production technology is simple and it can realize mass production which improves efficiency heavily.

  • The area of each cell can be made as 0.28~5.7㎡,compared to the crystalline silicon solar cell, its area is under 0.04㎡,which is easier to make and assemble.

2. Good scattered light function (good dim light function)

A lot of tests indicate the amount of electrical energy of amorphous silicon solar cells are 8-10% more than crystalline silicon solar cells at the same power each year. The main reason is that crystalline silicon solar cell doesnít have electricity generation when the light is dim. However, amorphous silicon solar cells still generate electricity.

3. It is less influenced by temperature and environmental change, its voltage and power reduce less than crystalline silicon solar cell when the temperature increases.

4. It can combine with the roof of building and glass curtain wall which becomes BIPV ,it can not only generate electricity ,but also save architecture materials that itís environment friendly. However, transfer efficiency of amorphous silicon solar cell is lower than crystalline silicon solar cell which has been developed for 20 years. With the development of amorphous silicon solar cell, its transfer efficiency will be improved and it will become the main stream of new energy market.
