Cadmium telluride (CdTe) has been recognized as a promising photovoltaic material for thin-film solar cells because of its near optimum bandgap of ~1.5 eV and high absorption coefficient. The energy gap is near optimum for a single junction solar cell and the high absorption coefficient allows films as thin as 2 μm to absorb more than 98% of the above-bandgap radiation. Cells with efficiencies near 17% have been produced for poly-CdTe materials. By alloying with mercury telluride (HgTe), Hg1… Expand
