SolarWind is committed to take Cadmium-Telluride thin film solar cell technology from laboratory level to mass production stage with higher efficiency and much lower cost. The mission of ASP is to provide clean PV energy to the world with the lowest cost. As of today, SolarWind is a company that can massively produce CdTe thin film PV module products other than First Solar US. in the world.
Currently, SolarWind does not only provides standard CdTe thin film solar modules with relatively high efficiency and stability to both domestic and foreign markets, but also offers the "turn-key" solution on PV power station to its clients. The landscape of SolarWind operations consists of 5 aspects: R&D for CdTe thin film solar cell technology. production-level equipment manufacturing. Production Line and technology BOT, Module Production and Sales, and EPC for PV Power Station projects. With a joint-venture company founded in 2016. SolarWind also extended its business operations in investing and operating PV power stations.
SolarWind has a highly talented and well experienced R&D team that are consisted of the world top-tier scientists and graduates from multiple first-class universities of China. During the last ten years, SolarWInd also built a three-tier system that consists of R&D on fundamental and core technology. R&D on production technology and international research cooperations. With this system, SolarWInd can not only be capable of supporting transferring its proprietary CdTe technology to partners, but also take the technology further by incorporating the latest development of the CdTe PV technology in the world.
SolarWind has excellent power generation performance. Our S1, S2, S4 series 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 by Advanced Solar Power (Hangzhou) Inc reaches to 12% and above on conversion efficiency. The S1 and S2 series products have obtained TUV, UL and CQC certifications.
LOW TEMPERATURE COEFFICIENT
The temperature coefficient of ASP 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 SolarWIndʼs CdTe thin film modules in real-life power-generation.
EXCELLENT LOW-IRRADIANCE EFFECT
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 which is made by an indirect band gap material.
GOOD STABILITY
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 SolarWIndʼs CdTe modules manufacturing process, SolarWInd CdTe module has a minimal breakage rate.
EXCELLENT APPEARANCE
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.
