“…In addition, it was worth noting that the high V oc value about 1.20 V was the highest result among all the DPP‐based nonfullerene small molecule acceptors to date according to the best knowledge of us. Later, a new nonfullerene small molecule acceptor D10 which was similar to the D2 acceptor was developed by Chen group . However, when blended with the P3HT donor, the PCE performance was only 2.43% of D10 compared to that 5.10% of D2, which was owing to the much lower J sc and FF values.…”

“…Owing to the broad and planar structure, high photochemical stability, easy synthesis, and modification, as well as high charge transport ability, common small molecules such as perylene diimides (PDI), naphthalene diimides (NDI), phthalimide (PhI), diketopyrrolopyrrole (DPP), and so on, are widely employed as the electron deficient materials. The strong electron‐withdrawing property of imides also makes them excellent candidates for functionalizing aromatic rings to create building blocks for electron‐deficient photoactive materials.…”

Recently, research on nonfullerene acceptors in organic solar cells has gradually become a hot topic due to such superior characteristics of light absorption and energy-level-convenient manipulation, multiformity of the photoactive material structures, as well as the extensive area in production compared to the fullerene derivatives. However, the nonfullerene acceptors evolved slowly before 2012 and, as a matter of fact, the power conversion efficiency values could only bear 2.0%. Strikingly, nonfullerene acceptors have developed at a fast pace since 2013, with the best device performance of 13.1% now. In this review, recent research progress on nonfullerene acceptors, including small molecules and polymers, are sorted and summarized on the basis of the different characteristics.

“…Recently Chen et al . reported two acceptors DPP38 and DPP39 based on DPP moiety attached with biphenyl and tetraphenyl ethylene moiety by direct arylation of mono‐phenyl capped DPP using tetrakis(4‐bromophenyl)ethene (TBPE) and tetrabromo‐biphenyl (TBBP) as arylating reagents . Tetraphenylethene (TPE) is well known building block used in the field of aggregation induced emission (AIE) and for making 3D non‐fullerene acceptor.…”

Organic solar cells (OSCs) have gained attention of the scientific community from the last decade and are now considered as one of the most important source for low-cost power production. The recent rapid progress in non-fullerene acceptors in BHJ indicates that they have potential to compete with fullerene-based BHJ OSCs. The present review addressed the systematic comparison among various acceptors (diketopyrrolopyrrole (DPP), benzothiadiazole (BTD) and perylenediimide (PDI) based acceptors) in order to design and improve the performance of small molecules based non-fullerene acceptors. This review focuses on the performance of small molecule non-fullerene acceptors based on DPP, BTD and PDI for OSCs with respect to the change in molecular structures, energy levels, and PCE. A systematic comparison on the effect of molecular architecture, side chains on their performance is provided with the intention of evaluating the challenge to make highly efficient acceptors for the next generation organic photovoltaics.

Solar cells are devices that convert light energy into electricity. To drive greater adoption of solar cell technologies, higher cell efficiencies and reductions in manufacturing cost are necessary. Fluorogens containing rotor structures may be helpful in addressing some of these challenges due to their unique twisted structures and photophysics. In this review, we discuss the applications of rotor-containing molecules as dyes for luminescent down-shifting layers and luminescent solar concentrators, where their aggregation-induced emission properties and large Stokes shifts are highly desirable. We also discuss the applications of molecules containing rotors in third-generation solar cell technologies, namely dye-sensitized solar cells and organic photovoltaics, where the twisted 3-dimensional rotor structures are used primarily for aggregation control. Finally, we discuss perspectives on the future role of molecules containing rotor structures in solar cell technologies.
