Open-circuit voltage and effective gap of organic solar cells

Abstract:

The open-circuit voltage (VOC) of an organic solar cell is limited by the donor-acceptor material system. The effective gap Egeff between the electron affinity of the acceptor and the ionization potential of the donor is usually regarded as the upper limit for VOC, which is only reached for T → 0 K. This relation is confirmed for a number of small-molecule bulk heterojunction p-i-n type solar cells by varying the temperatu...
