TL;DR: In this article, a semi-empirical model analysis and using the tandem cell strategy to overcome the low charge mobility of organic materials, leading to a limit on the active-layer thickness and efficient light absorption was performed.

TL;DR: The results demonstrate that the BDT unit could also be applied for designing NF-acceptors, and the fused-ring benzodi(cyclopentadithiophene) unit is a prospective block for designing new NF- acceptors with excellent performance.

TL;DR: The FDICTF modified by fusing the fluorene core in a precursor, yields 10.06% high power conversion efficiency, and demonstrates that the ladder and fused core backbone in A-D-A structure molecules is an effective design strategy for high-performance nonfullerene acceptors.

TL;DR: An unusually slow but ultimately efficient charge generation mediated by interfacial charge-pair states is observed, followed by effective charge extraction of the PBDB-T:NCBDT devices, among the best for solution-processed organic solar cells.

TL;DR: In this work, a tandem organic solar cell (TOSC) based on highly efficient nonfullerene acceptors (NFAs) with series connection type is demonstrated, with one of the top efficiencies reported to date in the field of organic solar cells.
