Abstract
A three-phase solid-state solar cell (SSSC) has been developed successfully using TaON nanoparticles or BiOI microspheres as a sensitizer material over a TiO2 film and CuI as a hole collector. Stable current (I sc)-voltage (Voc) curves are found under ultraviolet UV visible light irradiation with an efficiency of 0.15% and 0.10% for TaON- and BiOI-based solar cells, respectively. The observed photocurrents in SSSCs are approximately 10 and 48 times higher than those in wet-type solar cells (WSCs) based on TaON and BiOI, respectively. A plausible mechanism of charge transfer and hole filling is discussed in terms of the band gap energy and band position of the semiconductor materials.
