This structure is similar to the heterojunction in cigs cells.
Cadium solar panel.
Cadmium telluride cdte photovoltaics or also called cadmium telluride solar cell is a kind of photovoltaic pv technology that can produce electricity from sunlight using a thin film of compound cadmium telluride to absorb and convert sunlight into electricity.
The most common cdte solar cells consist of a simple p n heterojunction structure containing a p doped cdte layer matched with an n doped cadmium sulfide cds layer which acts as a window layer.
On a lifecycle basis cdte pv has the smallest carbon footprint lowest water use and shortest energy payback time of any current photo voltaic technology.
Cadmium telluride cdte solar panels as the second most common photovoltaic technology on the market behind traditional crystalline silicon cadmium telluride cdte panels are already a viable thin film solar panel solution.
