How is cdte made
Web2 apr. 2024 · Copper indium gallium selenide (CIGS) thin-film panels (try saying that five times fast!) are made by placing layers of copper, indium, gallium and diselenide on top of each other within conductive layers to create a powerful semiconductor. It can go on top of glass, plastic, steel or aluminum, depending on the desired use. Web1 INTRODUCTION. Photovoltaics (PV) using thin film CdTe as a photon absorber have been studied for several decades. CdTe was long recognized for its potential to surpass the conversion efficiencies of conventional silicon solar cells based on bandgap matching to the Shockley Queisser limit. 1 However, progress was slow in reaching this protentional with …
