Abstract

This article focuses on improving the charge transport, separation, and photovoltaic performance of antimony sulfide (Sb2S3)-sensitized titanium dioxide (TiO2) nanorod array (NAs) solar cells. TiO2 NAs with controllable microstructures were grown on fluorine-doped tin oxide (FTO)/TiO2 compact layer substrates via a hydrothermal method, and an ultra-thin cadmium sulfide (CdS) interlayer was deposited using the successive ionic layer adsorption and reaction (SILAR) method. The study found that optimizing the TiO2 NAs microstructure, introducing the CdS interlayer, and employing a spiro-OMeTAD:poly(3-hexylthiophene) (P3HT) complex as the hole transport material (HTM) enhanced charge separation and transport, increasing the power conversion efficiency (PCE) from 5.74% to 6.72%. These findings suggest a combined strategy of microstructure control, interlayer insertion, and HTM improvement as an effective approach to advance Sb2S3-sensitized TiO2 NAs solar cell performance.
