“…Third, it offers positions for introducing suitable side chains, which provide appropriate solubility and tune the packing structures in the solid state. However, FRAs usually suffer from high synthetic complexity and production costs, thus hampering their large-scale synthesis and limiting the commercialization of OSCs [40][41][42][43][44] .…”

Organic solar cells (OSCs) have experienced rapid development and achieved significant breakthroughs in power conversion efficiencies owing to the emergence of non-fullerene acceptors (NFAs) with ladder-type multiple fused ring structures. However, the high synthetic complexity and production cost of multiple fused ring NFAs hinder the commercial prospects of OSCs. In this context, the development of non-fused ring acceptors (NFRAs) with simple structures and facile synthesis has been proposed. In this mini review, we summarize the important progress in this field spanning from molecular design strategies to structure-performance relationships. Ultimately, with the aim of realizing the practical application of NFRAs in OSCs, we discuss the current challenges and future directions in terms of achieving high performance and low synthetic complexity simultaneously. These discussions provide valuable insights into the development of new NFRAs.

“…Bulk heterojunction (BHJ) organic solar cells (OSCs) have undergone an impressive progress within the last few years due to the significant innovations in non-fullerene acceptors and device craft. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] Over 18 % power conversion efficiency (PCE) and long-term device stability have been recorded in multiple cases. [5][6][7] Apart from the development of acceptors, interface engineering upon electrodes, that is, developing hole/electron transporting materials (HTMs/ETMs), is also a most effective strategy to further enhance the performance of OSCs to a new level.…”

Secondary doping has a long history of use in conductivity enhancement in poly (3,4-ethylenedioxythiophene) : poly(styrene sulfonate) (PEDOT : PSS). However, very little research has addressed its detrimental effect on application performance of PEDOT : PSS in organic solar cells. Herein, it was shown that the uneven drying of secondary dopant-water mixture results in a nonuniform/continuous film structure, causing severe damage to the device efficiencies (dropping about 8 and 23 % for poly [(2,6-(4,8-bis(5-(2-ethylhexyl) and poly[(2,6-(4,8-bis(5-(2) cells, respectively) and thermal stabilities. Moreover, a simple yet robust dialysis treatment was proposed to solve the issue of noncontinuity and retain the secondary doping's advantages of quinoid structure simultaneously, thus demonstrating a significant enhancement in device performance. This study will be of great importance to the future exploration of the next generation of post-treatment strategy.
