Highlights • Carefully tuning layer-by-layer thicknesses results in high-performance organic photovoltaics • A 16.21% efficiency is achieved, outperforming the bulk heterojunction counterpart • Photo-/thermal stability of layer-by-layer build is demonstrated for 9 distinct systems • Improved stabilities are due to reduction in phase aggregation seen in bulk heterojunctions Summary Tuning bulk heterojunctions is an important step for improving organic photovoltaic device performance; however,...
