In this work, a medium-bandgap polymer POBDFBT was synthesized and served as the single donor in binary and ternary polymer solar cells (PSCs) together with two acceptors (ITIC and PC71BM). A promising power conversion efficiency (PCE) of 7.91% with

Tuning the structure of both polymer donors and acceptors, and development of novel matched donor/acceptor pairs are essential steps to enhance the power conversion efficiency (PCE) and stability of all-polymer solar cells (PSCs). Here, two weakly cr

A low-cost biomimetic haze film (BHF) is fabricated by one-step replica molding of the petal texture of yellow roses with polydimethylsiloxane (PDMS). The BHF possesses very high haze transmission (75%) and ultrahigh diffusion transmittance (97%), su

Direct arylation was used to synthesize a series of novel terthiophene (T3)-based D–A1–D–A2 polymers and D–A2–D monomers in fewer synthetic steps. In these T3-based D–A1–D–A2 polymers, pyrrolo[3,4-c]pyrrole-1,4-dione (DPP) was selecte

We demonstrate a simple rubbing hole injection layer (HIL) to form surface relief gratings (SRGs) on the functional layers of polymer solar cells (PSCs). PSCs studied in this work consist of an ITO/PEDOT:PSS(HIL)/P3HT:PCBM(photoactive layer)/LiF/Al s
