Photovoltaic Efficiency Enhancement by the Generation of an Embedded Silica‐Like Passivation Layer along the P3HT/PCBM Interface Using an Asymmetric Block‐Copolymer Additive

Abstract: A new approach to improve the power conversion efficiency of polymer bulk-heterojunction solar cells is demonstrated by generating a silica-like passivation layer embedded along the three-dimensionally intertwined interfaces between the nanoscopic domains of P3HT and PCBM by addition of an aymmetric block copolymer containing a short organo-silica precursor.

“…225 In recent 5 years, various block copolymer compatibilizers were synthesized and used as the third component in OSCs. [226][227][228][229][230][231][232][233][234][235][236][237][238][239][240][241] Block copolymers with rodcoil structure were the most widely used polymer additives. Han et al 226 used an asymmetric rod-coil block copolymer P3HT-b-PTMSM in P3HT/PC 61 BM blend to form a passivation layer between the microscopically phase-separated D/A domains.…”

“…BHJSCs were fabricated by adding an asymmetric rod − coil block copolymer P3HT‐ b ‐PTMSM ( P12 , Fig. ) consisting of P3HT as the majority block and poly[(3‐trimethoxysilyl)propyl methacrylate] (PTMSM) as the minority block in a P3HT:PCBM mixture followed by brief thermal treatment . Upon evaporation of the solvent, the P3HT block of P12 cocrystallized with the P3HT chains and then phase separated from the PCBM domains, resulting in PTMSM blocks sitting at the interfacial regions between the P3HT and PCBM domains (Fig.…”

“…Controlling this feature of thermal stability is thus a key‐parameter in determining OPV efficiencies and lifetimes. Several approaches have been taken to manage this aggregation, and include processing techniques such as thermal and solvent annealing, and the employment of molecular additives, and macromolecular compatibilisers …”
