CdTe thin-film solar panels are comprised of three main parts, having a layer for the semiconductor, one for the protection, and one for the conduction. These parts are:Photovoltaic material, Conductive sheet, Protective layer.
CdTe Thin Film Solar Panel with Transparency
EXCELLENT POWER GENERATION PERFORMANCE
CdTe thin film modules have a high efficiency and a proven-excellent record on power generation performance.
Comparing to crystalline silicon solar module, CdTe thin film module generates 5-10% more in average of electricity every year.
HIGH CONVERSION EFFICIENCY
Cadmium Telluride is a semiconductor compound with a high absorption coefficient - 100 times higher than silicon. The band gap width of cadmium telluride is more suitable for photovoltaic energy conversion than silicon. To absorb the same amount of light, the thickness of cadmium telluride film is only one hundredth that of silicon wafer. Today, the world record of cadmium telluride thin film conversion efficiency has reached 21% in the laboratory. And the CdTe thin film solar module with dimension of 1200mm * 600mm produced reaches to 12% and above on conversion efficiency. series products have obtained TUV, UL and CQC certifications.
LOW TEMPERATURE COEFFICIENT
The temperature coefficient of CdTe thin film solar module is only about -0.21%/℃, as the traditional silicon solar module temperature coefficient reaches to -0.48%/℃. For most of high solar irradiance regions on earth, the temperature of solar module at working can reach to 50℃ or above. Thus this fact have greater impact to the conversion efficiency of crystalline silicon solar modules than to ASPʼs CdTe thin film modules in real-life power-generation.
No intrinsic light-induced degradation effects.
LOW HOT SPOT EFFECT
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.
MINIMAL BREAKAGE RATE
Contributed by a proprietary technology adapted in CdTe modules manufacturing process, CdTe module has a minimal breakage rate.
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.
