Over the last 5 years, research on the synthesis, device engineering, and device physics of
solution‐processed small molecule solar cells (SMSCs) has rapidly expanded …

Low-temperature solution-processed photovoltaics suffer from low efficiencies because of
poor exciton or electron-hole diffusion lengths (typically about 10 nanometers). Recent …

In the last few years, the performance of organic solar cells (OSCs) based on bulk
heterojunction (BHJ) structure has remarkably improved. However, for a large scale roll to …

Modest exciton diffusion lengths dictate the need for nanostructured bulk heterojunctions in
organic photovoltaic (OPV) cells; however, this morphology compromises charge collection …

Grazing incidence X‐ray scattering (GIXS) provides unique insights into the morphology of
active materials and thin film layers used in organic photovoltaic devices. With grazing …
