摘要 |
A photovoltaic device is presented. The photovoltaic device includes a layer stack; and an absorber layer is disposed on the layer stack. The absorber layer includes cadmium, tellurium, and selenium. A semiconductor layer is further disposed on the absorber layer, wherein a valence band offset between the semiconductor layer and the absorber layer is less than about 1.3 electron Volts, and a band gap of the semiconductor layer is in a range from about 1.2 electron Volts to about 3.5 electron Volts. |
