Order enables efficient electron-hole separation at an organic heterojunction with a small energy loss. (Springer Nature, 2018-01-18)Donor-acceptor organic solar cells often show low open-circuit voltages (VOC) relative to their optical energy gap (Eg) which limit power conversion efficiencies to around 12%. This energy loss is attributed, in part, to ...
(Nature Publishing Group, 2013-11-17)Singlet exciton fission, the spin-conserving process that produces two triplet excited states from one photoexcited singlet state, is a means to circumvent the Shockley–Queisser limit in single-junction solar cells. Although ...
(Nature Publishing Group, 2013-08-07)In biological complexes, cascade structures promote the spatial separation of photogenerated electrons and holes, preventing their recombination. In contrast, the photogenerated excitons in organic photovoltaic cells are ...
