Low energy loss and efficient charge separation under small driving forces are the
prerequisites for realizing high power conversion efficiency (PCE) in organic photovoltaics …

We developed three narrow band-gap polymer acceptors PF2-DTC, PF2-DTSi, and PF2-
DTGe with different bridging atoms (ie, C, Si, and Ge). Studies found that such different …

Herein, we investigated a series of fullerene-free organic solar cells (OSCs) based on six
different donor: acceptor (D: A) blends with varied highest occupied molecular orbital …

A" face-on" molecular orientation is essential for photovoltaic materials with efficient vertical
carrier transport, but understanding how the molecular structures control their orientations …

The exploration of high‐performance and low‐cost wide‐bandgap polymer donors remains
critical to achieve high‐efficiency nonfullerene organic solar cells (OSCs) beyond current …

Bulk heterojunction (BHJ) organic solar cells (OSCs) have achieved great success because
they overcome the shortcomings of short exciton diffusion distances. With the progress in …

To elevate the performance of polymer solar cells (PSC) processed by non‐halogenated
