Abstract:A challenge in PV designs, including those with an electron transport layer (ETL), is the presence of 'parasitic absorbers'. These are layers that absorb light without significantly converting it to electrical current, impacting the total external quantum efficiency (EQE). Strontium titanate (STO), a high-band-gap (3.20 eV) perovskite metal oxide, holds promise as an electron transport layer (ETL) for solar energy harvesting. Despite STO's potential, it primarily operates in the UV spectrum, not fully utilizin… Show more
