Hole-Transporting Materials for Perovskite Solar Cells
Hole transport materials (HTMs) are one of the key compounds in perovskite solar cells (PSCs), both for the n-i-p and the p-i-n device structures. HTMs can also be used to replace the liquid electrolyte of conventional dye-sensitized solar cells to make solid-state DSSC (ss-DSSC) devices.
