    • An improved photovoltaic device characterized by long term stability in its photoconversion ability. The device is adapted to absorb incident light throughout a substantial portion of the bulk of the photoactive region thereof in a substantially uniform manner. Said uniform absorption of light is provided by grading the band gap of at least a portion of the semiconductor material of the photoactive region thereof such that the graded portions most proximate the light incident surface of the photovoltaic device have a wider band gap than do those portions more distal from the light incident surface. The band gap gradation may be smooth or stepped, and may be accomplished by compositional variation of the semiconductor materials forming the photoactive region. A method for fabricating the stable photovoltaic device of the instant invention is also provided.
    • 一种改进的光电器件,其特征在于其光转换能力的长期稳定性。 该装置适于以基本均匀的方式吸收入射光的大部分光活性区域的大部分。 通过对其光活性区域的半导体材料的至少一部分的带隙进行分级来提供光的均匀吸收,使得最靠近光伏器件的光入射表面的渐变部分具有比这些部分更宽的带隙 远离光入射面。 带隙层级可以是平滑的或阶梯状的,并且可以通过形成光活性区域的半导体材料的组成变化来实现。 还提供了用于制造本发明的稳定光伏器件的方法。
