Abstract
Perovskite Solar Cells A novel dibenzofuran-terminated spiro-type hole transport material with extending π-conjugation is designed and developed. The developed spiro-BNF has improved hole mobility and glass transition temperature than spiro-OMeTAD, which also form superior morphology on the perovskite layer. The perovskite solar cells employing spiro-BNF display a power conversion efficiency of 23.65% with greatly enhanced stability.
