Cadmium telluride (CdTe) photovoltaics describes a photovoltaic (PV) technology that is based on the use of cadmium telluride, a thin semiconductor layer designed to absorb and convert sunlight into electricity. CdTe PV is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi-kilowatt systems.

CdTe PV is a solution to key ecological issues including climate change, energy security, and water scarcity, across a range of application scenarios (e.g. commercial rooftop applications or large scale ground mount applications).

CdTe advantages:
*High Conversion Efficiency
Cadmium Telluride (CdTe) is a compound semiconductor with high absorption coefficient, 100 times higher than silicon. The energy gap width of cadmium telluride makes it the most suitable material for photovoltaic energy conversion, higher than silicon – with only one hundredth of thickness, the cadmium telluride can absorb same amount of light as silicon does.
*High Power Output
With the lower temperature coefficient, the better low-light effect and weak heat spot effect being provide in them, CdTe modules generate 10% more power than same rating modules made with crystalline silicon.
*Low Temperature Coefficient
The temperature coefficient of CdTe thin film solar module is only about -0.21%/K, make it much more heat resistant than crystalline solar modules.
*Excellent Low-light Effect - It works even indoor!
Cadmium telluride is a direct band gap material with high absorption for the full spectrum. Under lower-light condition, such as dawn, with dusk and diffuse light, the power generation capability of CdTe thin film solar module has been proven to be better than the crystalline silicon solar module which was made of indirect band gap material.
*Weak hot spot effect:
The structural features of CdTe thin film modules, help to avoid the hot spot effect on products. Thus, the safety, longevity, performance of CdTe panels have also greatly improved.
*Good stability
No intrinsic light-induced attenuation effects.
* UL and ISO 9001:2000 Certified
* 25-year power warranty
