Photovoltaic Properties

Although polymer materials possess the advantages such as low cost and easy fabrication of flexible and large-scale film for the application in photovoltaic devices, the performance of polymer-based solar cells, especially energy conversion efficiency is inferior to their inorganic counterpart due to the shorter charge diffusion length caused by the comparatively lower electric field between the electrodes. This paper reviewed the strategies to improve their photovoltaic properties mainly concentrated on modifying the polymer materials and ameliorating the device configuration. First, polythiophene (PT), poly(phenylene vinylene) (PPV), polyfullerene, and other novel polymer materials were introduced and the effective ways to modify their derivatives with more advantages were described in detail, for instance, copolymerization, incorporating additives and dyes, etc. Furthermore, the content of ameliorating the device configuration encompassed on inverted architecture, tandem structure, the introduction of buffer layers, thermal annealing, and the integration of optimized conditions. Finally, the effects of the improvement methods were concisely summarized, and the perspectives of the future research were put forth.

Abstract In this study, strong electron-withdrawing fluorine (F) and cyano (CN) substituents are selectively incorporated into the quinoxaline unit of two-dimensional (2D) D–A-type polymers to investigate their effects on the photovoltaic properties of the polymers. To construct the 2D polymeric structure, electron-donating benzodithiophene and methoxy-substituted triphenylamine are directly linked to the horizontal and vertical directions of the quinoxaline acceptor, respectively. After analyzing the structural, optical, and electrochemical properties of the resultant F- and CN-substituted polymers, labeled as PBCl-MTQF and PBCl-MTQCN, respectively, inverted-type polymer solar cells with a non-fullerene Y6 acceptor are fabricated to investigate the photovoltaic performances of the polymers. It is discovered that the maximum power conversion efficiency of PBCl-MTQF is 7.48%, whereas that of PBCl-MTQCN is limited to 3.10%. This significantly reduced PCE of the device based on PBCl-MTQCN is ascribed to the formation of irregular, large aggregates in the active layer, which can readily aggravate the charge recombination and charge transport kinetics of the device. Therefore, the photovoltaic performance of 2D quinoxaline-based D–A-type polymers is significantly affected by the type of electron-withdrawing substituent.

It is discovered that the maximum power conversion efficiency of PBCl-MTQF is 7.48%, whereas that of PBCl-MTQCN is limited to 3.52%. This significantly reduced PCE of the device based on PBCl-MTQCN is ascribed to the formation of irregular, large aggregates in the active layer, which can readily aggravate the charge recombination and charge transport kinetics of the device. Therefore, the photovoltaic performance of 2D quinoxaline-based D–A-type polymers is significantly affected by the type of electron-withdrawing substituent.

We found that inserting silver nanoparticles (AgNPs) between two layers of reduced grapheme oxide (rGO) has an effect on tailoring the work function of rGO. The utilization of rGO/AgNPs/rGO sandwich structure as the hole extraction layer in polymer solar cells is demonstrated. Solution-processable fabrication of this sandwich structure at the ITO/active layer interface facilitates the extraction of hole from active layer into ITO anode because of lowering the barrier level alignment at the interface. It results in an improvement of the short circuit current density and the overall photovoltaic performance.
