We report all solid-state nanostructured inorganic-organic heterojunction solar cells fabricated by depositing Sb(2)S(3) and poly(3-hexylthiophene) (P3HT) on the surface of a mesoporous TiO(2) layer, where Sb(2)S(3) acts as an absorbing semiconductor and P3HT acts as both a hole conductor and light absorber. These inorganic-organic light harvesters perform remarkably well with a maximum incident-photon-to-current efficiency (IPCE) of 80% and power conversion efficiency of 5.13% under air-mass 1.5 global (AM 1.5G) illumination with the intensity of 100 mW cm(-2). These devices are highly stable under room light in air, even without encapsulation. The present findings offer novel directions for achieving high-efficiency solid-state solar cells by hybridization of inorganic-organic light harvesters and hole transporters.
我们报告了所有固态纳米结构的无机-有机异质结太阳能电池的制备，方法是在介孔 TiO2 层的表面沉积 Sb2S3 和聚（3-己基噻吩）（P3HT），其中 Sb2S3 作为吸收半导体，P3HT 同时作为空穴导体和光吸收体。这些无机-有机光收集器在空气环境下，强度为 100 mW cm(-2) 的 AM 1.5G 光照下，表现出优异的性能，最大入射光子到电流效率（IPCE）为 80%，功率转换效率为 5.13%。这些器件在空气中的室内光下非常稳定，即使没有封装。本研究结果为通过无机-有机光收集器和空穴传输体的杂交来实现高效固态太阳能电池提供了新的方向。
