Processing additives are used in organic photovoltaic systems to optimize the active layer film morphology. However, the actual mechanism is not well understood. Using X-ray scattering techniques, we analyze the effects of an additive diiodooctane (DIO) on the aggregation of

Organic photovoltaics (OPVs) represent a low-cost, lightweight, and scalable alternative to conventional solar cells. While significant progress has been made in the development of conventional bulk heterojunction cells, new approaches are required to achieve the performance and stability necessary to enable commercially successful OPVs.
Professor Chen (Nankai University, China) and his team explain the strategies behind their recent record-breaking organic solar cells, reaching a power conversion efficiency of 17.3%.
