Abstract

Hybrid inorganic–organic heterojunction solar cells (HHSCs) are successfully fabricated using Sb₂S₃ as a light-absorbing semiconductor, TiO₂ nanorods (NRs) as an electron-transport layer, and poly-3 (hexylthiophene) (P3HT) as both a hole conductor and light absorber. The enhanced photo-to-electric conversion performance is expected to (1) enhance optical absorption in the visible light region by Sb₂S₃ and (2) photo-generate highly efficient charge carrier separation at TiO₂/Sb₂S₃ and Sb₂S₃/P3HT heterojunction interfaces. The power conversion efficiency (PCE) of HHSCs improves approximately fourfold by inserting the Sb₂S₃ layer, which can be further enhanced about four more times by optimizing the length of TiO₂ nanorod arrays (NRAs). Finally, the mechanism to illustrate the effect of the length of TiO₂ NRs on the PCE is discussed. This leads to a theory for achieving high-efficiency inorganic–organic solar cells.
