WebIn contrast, the system consisting of mixed domains and lower crystallinity (SM2) shows both excellent exciton harvesting and low charge recombination losses. Importantly, the onset of large, pure crystallites in the latter (SM2) system reduces efficiency, pointing to possible differences in the ideal morphologies for SM‐based BHJ solar cells compared … Web17 mrt. 2024 · Abstract. In ternary organic solar cells (TOSCs), three different components are mixed to form the photoactive layer, opening up opportunities to boost the power conversion efficiency — for ...
Web11 dec. 2015 · A typical OSC consists of domains that arise from blending two materials – donor and acceptor – that conduct the holes and electrons respectively. The exciton travels to the interface of these domains, the exciton separates into charges, and the charges then travel to electrodes for collection. Sounds simple enough, right? Well, not really.
