CdTe Thin Film Solar Panel


CdTe thin film modules have a high efficiency and a proven-excellent record on power generation performance.


CdTe thin film solar module with dimension of 1200mm * 600mm produced by Optimum Sun reaches to 12% and above on conversion efficiency..


The temperature coefficient of CdTe thin film solar module is only about -0.21%/degree, as the traditional silicon solar module temperature coefficient reaches to -0.48%/degree. For most of high solar irradiance regions on earth, the temperature of solar module at working can reach to 50dergee or above. Thus this fact have greater impact to the conversion efficiency of crystalline silicon solar modules than to CdTe thin film modules in real-life power-generation.

Cadmium telluride is a direct-band-gap material with high absorption for the full spectrum.Under low-light condition, in dawn, dusk of a day or in a diffuse lighting, the power generation performance of CdTe thin film solar module has been proven to be higher than that of crystalline silicon solar module.


No intrinsic light-induced degradation effects.


The elongated cells of CdTe thin film module help to reduce the hot spot effect of module, which leads to a great advantage of improving the power generation capacity, ensuring the safety in usage and product life.


CdTe modules have uniformity color - pure black which provides an excellent appearance, fit best in buildings that have higher standards on appearance, unity and energy-independance.

Safety and Environment-Friendly
Scientists in Brookhaven national laboratory US systematically studied the heavy metal emissions from renewable energy, such as crystalline silicon solar cell, CdTe thin film solar cell, and traditional energy, such as coal, oil, natural gas and nuclear energy. In the analysis of solar cell, the full life-cycle process was considered including the original processing of ores required for the solar cell materials, the production and use of solar cells, etc.. The study results show that the highest cadmium emission is oil which achieves 44.3g/GWh, the second highest is coal about 3.7g/GWh. The cadmium emission of CdTe thin film solar module is only 0.3g/GWh as same as natural gas.
In the summary, with the lowest cost of power generation, the CdTe thin film solar module can help the world to achieve the revolution of clean energy and harvests of both economic and environmental benefits.
