Abstract: (746 Views)
Recently, adopted perovskite solar cells (PSCs) as the third generation of solar cells based on perovskite materials (ABX3). PSCs have their unique properties, such as low-cost, band-gap tunability, simple fabrication, the opportunity of substrates, and high performance. Titanium dioxide (TiO2) is an attractive choice for the electron transporting layer (ETL) in PSCs. In the current study, lithium fluoride (LiF) dopant was used to enhance electrical properties of the (ETL) and perovskite performance. The results showed that LiF-doping increased the conductivity of TiO2, suppressed electron-hole recombination at ETL/perovskite interface, and improved crystallinity properties of the perovskite layer. Through ETL modification, the performance of PSCs without hole transporting layer (HTL) 48% improved and endowed the devices with a champion power conversion efficiency of 9.33%.
