Layered optimization strategy enables over 17.8% efficiency of layer-by-layer organic photovoltaics

The role of structural parameters on efficiency and transparency of semi-transparent non-fullerene organic solar cell

“…Then, PCE has been decreasing as FF decreases because of the explained recombination effects. FF almost declined with increasing active layer thickness, which is associated with the decrease in shunt resistance values 39,40 . Although the J sc is highest for the active layer with a thickness of 143 nm, the FF is low and is 49.6%.…”

Highly sensitive broadband photomultiplication type all-polymer photodetectors and their applications in optical pulse counting

“…4d, which are maintained at about 90% of the initial EQE values after being exposed for 120 h. The good stability of optimal PM-APDs benefits from the stable morphology of all-polymer active layers with strong interchain packing. 46–48 The optimal PM-APDs exhibit excellent photoelectric response capability, weak light detection capability and stability, which should have potential applications in practical photoelectric detection.…”

Machine learning with quantum chemistry descriptors: predicting the solubility of small-molecule optoelectronic materials for organic solar cells

“…It is well known that the morphology of the photoactive layer is mainly determined by the solubility, crystallinity, and miscibility of donors and acceptors. 23 Layer-bylayer OSCs exhibit great potential in achieving high PCE as reported by Zhang et al 24,25 It is well known that the solubility of optoelectronic materials is important for fabricating layer-bylayer OSCs, and will affect the interface morphology between different layers. Therefore, solubility is a critical physical property of donor and acceptor materials, and should be considered during the design of new high-performance donors and acceptors.…”
