Pinholes and morphology of CdS films : the effect on the open circuit voltage of CdTe solar cells
Cadmium telluride (CdTe) solar cells are among the many types of solar cells that have the potential to harness solar energy. CdTe has a band gap of ~1.5 eV that very closely matches the spectrum of the sun. In addition, being a thin film solar cell, the entire thickness of the solar device is a few microns and the energy required to manufacture thin film solar cells is much less than some of the more widely used solar cells. Nevertheless, CdTe solar cells lag behind solar cells of similar band gap materials in open circuit voltage. This voltage deficit can be attributed to many factors among ...
