无机和有机材料的纳米结构复合材料在电子和光电子器件应用中引起了广泛的兴趣。在本文中，我们介绍了一种通用的方法，用于制造金属硫化物纳米颗粒/聚合物薄膜采用低成本和低温路线兼容的大规模设备制造。我们的方法是基于在半导体聚合物膜中的可溶液加工的金属黄原酸盐前体络合物的受控原位热分解。为了证明我们的方法的多功能性，我们制造了CdS/P3 HT纳米复合材料膜，并表明聚合物膜内的金属硫化物网络有助于吸收可见光，并能够实现高产量的CdS/P3 HT异质结的电荷光生。基于这种纳米复合膜的光伏器件显示出在全AM1.5照明下0.7%的太阳光到电能的转换效率和在10%入射功率下1.2%的太阳光到电能的转换效率，证明了这种纳米复合膜用于低成本光伏器件的潜力。
Nanostructured composites of inorganic and organic materials are attracting extensive interest for electronic and optoelectronic device applications. In this paper, we introduce a general method for the fabrication of metal sulfide nanoparticle/polymer films employing a low-cost and low temperature route compatible with large-scale device manufacturing. Our approach is based upon the controlled in situ thermal decomposition of a solution processable metal xanthate precursor complex in a semiconducting polymer film. To demonstrate the versatility of our method, we fabricate a CdS/P3HT nanocomposite film and show that the metal sulfide network inside the polymer film assists in the absorption of visible light and enables the achievement of high yields of charge photogeneration at the CdS/P3HT heterojunction. Photovoltaic devices based upon such nanocomposite films show solar light to electrical energy conversion efficiencies of 0.7% under full AM1.5 illumination and 1.2% under 10% incident power, demonstrating the potential of such nanocomposite films for low-cost photovoltaic devices.
