Wide bandgap polymer donor PM6 and narrow bandgap polymer acceptor PY-IT were
selected to construct all-polymer solar cells (all-PSCs) with a layer-by-layer (LbL) or bulk …

All‐polymer solar cells (all‐PSCs) exhibit excellent stability and readily tunable ink viscosity,
and are therefore especially suitable for printing preparation of large‐scale devices. At …

A critical bottleneck for further efficiency breakthroughs in organic solar cells (OSCs) is to
minimize the non‐radiative energy loss (eΔVnr) while maximizing the charge generation …

The intrinsic electronic properties of donor (D) and acceptor (A) materials in coupling with
morphological features dictate the output in organic solar cells (OSCs). New physical …

Ternary-blend organic solar cells (TOSCs) are fabricated with PM6: BTP-4F-12 as the host
