Nettet17. okt. 2013 · Abstract: Long, balanced electron and hole diffusion lengths greater than 100 nanometers in the polycrystalline organolead trihalide compound CH3NH3PbI3 are critical for highly efficient perovskite solar cells. We found that the diffusion lengths in CH3NH3PbI3 single crystals grown by a solution-growth method can exceed 175 … Nettet1. mai 2024 · Indium vanadate (InVO 4) is considered to be a promising photocatalyst due to its strong absorption in the visible light region and potential to overall split water.However, it is hardly used for water splitting on account of its short diffusion length of holes. In this work, surface polarization based on inorganic acid modification was …
