Cadmium Telluride

In this "thin-film" technology, a thin layer of CdTe absorbs light, which excites charged particles called electrons; when the electrons move, they create an electric current. CdTe cells are referred to as thin-film because they are more

The back contact issue is not unique to CdTe—it is also believed to be a limiting factor in some other thin film solar cell technologies; such as the perovskite structure materials

Research on ultra-thin cadmium telluride heterojunction thin film solar

Cadmium Telluride (CdTe) thin film solar cells have many advantages, including a low-temperature coefficient (−0.25 %/°C), excellent performance under weak light conditions, high

Cadmium telluride photovoltaics

OverviewBackgroundHistoryTechnologyMaterialsRecyclingEnvironmental and health impactMarket viability

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