Over 20.1% Efficiency of Layer‐by‐Layer Organic Photovoltaics by Incorporating High Hole Mobility Material with Crystallinity

ABSTRACT Series of layer‐by‐layer organic photovoltaics (LOPVs) were constructed with polymer D18 as donor and small molecule L8‐BO with self‐dissociation characteristics as acceptor. The high hole mobility and good crystallinity semiconductor C8‐BTBT was deliberately incorporate...
