Tail state limited photocurrent collection of thick photoactive layers in organic solar cells
The power conversion efficiencies of most organic solar cells roll off quickly with thickness more than 100 nm. Here, Wu et al. show that avoiding excessive charge accumulation in the intra-bandgap tail states is vital to maintain the photocurrent generation at high thickness.
