In comparison with the common-used electron donor (D)-electron acceptor (A) type symmetric polymers with regular structures, their asymmetric counterparts have received much less attention and seldom been applied in polymer solar cells. Since the pre

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

In this work, we reported two wide band-gap donor–acceptor (D–A) photovoltaic materials based on asymmetric benzodithiophene units with a bare phenyl or alkoxyl chain modified phenyl group as one of the substitutions. The optical band-gaps of the

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

In this paper, foldable polymer solar cells (PSCs) were fabricated on woven fabrics by a free-standing, wet transfer method. A new concept of ‘water-borne PSCs’ was proposed to show the ultra-stability of organic photoactive materials under extre

Reduction of optical loss in thin-film solar cells, such as polymer solar cells and perovskite solar cells, is a key issue to promote device performance. A number of optical strategies have been investigated to enhance absorption. Among them, the lig

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

A novel four-armed triphenylamine (TPA)-based molecule named (TPATh)4TPA2B with 4,7-bis(4-diphenylaminophenyl)-2,1,3-benzothiadiazole unit as the central building block and triphenylamine-3-dodecylthiophene unit as the arms and a bi-armed TPA-based m

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
