CdTe Thin Film Solar Module

Features

EXCELLENT POWER GENERATION PERFORMANCE

SF series CdTe thin film modules have a high efficiency and a proven excellent

record on power generation performance.

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 22.1% in the laboratory. And the CdTe thin film solar module produced by Solar First reaches to 14% and above on conversion efficiency. The SF series products have obtained TUV, UL and CQC certififications.

LOW TEMPERATURE COEFFICIENT

The temperature coefficient of SF 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

EXCELLENT LOW-IRRADIANCE EFFECT

Cadmium telluride is a direct-band gap material with high absorption for the full spectrum. Under low lightcondition, 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 SF's CdTe modules manufacturing process, SF 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.
