TL;DR: In this paper, a novel bithiophene carrying a fulleropyrrolidine substituent was presented, whose electrochemical polymerization affords an electron donor−acceptor material that has been studied by means of electrochemical and spectroscopic techniques.

TL;DR: In this article, Wang et al. showed that the V-oc of CH3NH3PbBr3 cells is primarily limited by the interface losses induced by the charge extraction layer rather than by bulk dominated recombination losses.

TL;DR: In this paper, the physical properties of these bipolar devices are discussed with respect to the transport properties of the network, and possible enhancement is discussed by analyzing the single parameters contributing to the AM 1.5 efficiency in plastic solar cells, namely, the open circuit voltage (Voc), the short circuit current (Isc), the fill factor (FF), as well as the absorption matching to the solar spectrum.

TL;DR: In this article, the device physics of bulk heterojunction solar cells based on a nonfullerene acceptor (IDTBR) in combination with poly(3-hexylthiophene) (P3HT) are elucidated, showing an unprecedentedly low bimolecular recombination rate.
