Thin Film Solar Modules

Thin Film Solar Modules

There are three common thin-film divisions: amorphous silicon (a-Si), cadmium telluride (CdTe), and copper indium gallium selenide (CIGS) or gallium-free CIS. CIS and CIGS modules are usually produced using co-evaporation or co-deposition. Copper, indium, selenide and (sometimes) gallium are deposited onto the substrate at different temperatures to mix together. Comparatively, a typical 60-cell c-Si module averages a power output between 250 and 350 W with an efficiency more near 18 or 19%, with high-efficiency brands performing even better. One would need more thin-film modules and more area to produce the same power as a smaller group of c-Si. Crystalline silicon modules are just more consistently dependable for the majority of solar markets, and that’s why they are the dominant panel choice.
