What is the photovoltaic effect in organic materials?

Until the beginning of twenty-first century, the photovoltaic effect in organic materials did not look very exciting due to the low mobility of charge carriers and strong trapping of the excitons before their separation in the heterojunction. This resulted in rather small external quantum efficiency (EQE) and energy conversion (< 1%).
