Cadmium telluride is a direct bandgap material with bandgap energy of about 1 45 defined ev which is well matched to the solar spectrum and nearly optimal for converting sunlight into electricity using a single junction.
Cadmium telluride solar panels.
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.
Pv solar cells based on cdte represent the largest segment of commercial thin film module production worldwide.
Cadmium telluride pv is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi kilowatt systems.
First solar a us based manufacturer makes attractive pv modules that can be used in home applications.
Cadmium telluride solar cells the united states is the leader in cadmium telluride cdte photovoltaic pv manufacturing and nrel has been at the forefront of research and development in this area.
