Concentration-dependent impact of alkali Li metal doped mesoporous TiO2 electron transport layer on the performance of CH3NH3PbI3 perovskite solar cells
Original language description
TiO2 is commonly employed as an electron transport layer (ETL) in mesoscopic n−i−p perovskite solar cells (PSCs). However, the low electron mobility, low electrical conductivity, and high electronic trap states of TiO2 have negative impacts on further enhancement of PSC performance. Metal doping is an efficient way to improve the electronic properties of TiO2 films. In this work, we investigate the concentration-dependent impact of alkali lithium metal doping of the mesoporous TiO2 ETL on the performance of mesoscopic CH3NH3PbI3 PSCs. It was found that Li doping results in improvement in electrical conductivity and electron mobility and reduces the number of electronic trap states arising due to the oxygen vacancies within TiO2 lattice. The device performance relies on the concentration of Li doping, and the power conversion efficiency (PCE) of the PSC was improved from 13.64% to 17.59% for a Li doped mesoporous TiO2 layer with an optimized concentration of 30 mg/mL.n
