Zoom Solar Low Light Cdte BIPV Panel for Roof and | RFQ Sourcing Details

Product Structure: The structure of cadmium ctive oxide layer (TCO layer), cadmium sulfide (CdS) window layer, cadmium Cd. Te is a direct bandgap material with good absorption of the entire spectrum.

Therefore, its luminous effect in weak light conditions such as early morning, evening, snow, dust, and haze is significantly better than that of indirect bandgap crystalline silicon . (2) Low temperature coefficient Cd.

Te material has a relatively low thermal expansion coefficient and thermal conductivity, so its performance is stable when working at high temperatures. The temperature coefficient of cadmium . This means that in high temperature environments, cadmium gap width of Cd. Te is generally around 1.47eV.

This width makes its spectral response very compatible with the solar spectrum and has a high absorption rate. It can absorb more than 90% of visible light with a thickness of only 1μm, which is 1/100 of that of single-crystalline silicon. It is very suitable for making the absorption layer of thin-film solar .

The theoretical photoelectric conversion efficiency of cadmium m thickness required for the absorption layer of cadmium addition, the manufacturing process is relatively simple, making it easier to achieve large-scale production.

(5) Good power generation stability The spectral absorption of cadmium ease in humid climates like crystalline silicon modules. Crystalline silicon
