Cadmium telluride cdte is the most common type of thin film solar cell in production.
Cadium solar panel.
This structure is similar to the heterojunction in cigs cells.
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.
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.
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.
