混合金属硫化物/聚合物太阳能电池活性层采用基于半导体聚合物膜中的单源金属黄原酸盐前体的原位热分解的方法制造。薄膜的纳米形貌，在施主-受主异质结的电荷光生产率和器件性能被证明是依赖于退火温度。基于这种层的光伏器件显示出在AM1.5太阳光照下表现出类似于2.2%的功率转换效率，从而证明了这种纳米复合膜用于光伏器件应用的潜力。
Hybrid metal sulfide/polymer solar cell active layers are fabricated employing an approach based upon the in-situ thermal decomposition of a single source metal xanthate precursor in a semiconducting polymer film. The nanomorphology of the film, the charge photogeneration yield at the donor-acceptor heterojunction and device performance are shown to be dependent upon the annealing tern perature. Photovoltaic devices based upon such layers are shown to exhibit power conversion efficiencies of similar to 2.2% under AM1.5 solar illumination thus demonstrating the potential of such nanocomposite films for photovoltaic device applications.
