Beschreibungen/Notizen

• Recent research efforts on solution‐processed semitransparent organic solar cells (OSCs) are presented. Essential properties of organic donor:acceptor bulk heterojunction blends and electrode materials, required for the combination of simultaneous high power conversion efficiency (PCE) and average visible transmittance of photovoltaic devices, are presented from the materials science and device engineering points of view. Aspects of optical perception, charge generation–recombination, and extraction processes relevant for semitransparent OSCs are also discussed in detail. Furthermore, the theoretical limits of PCE for fully transparent OSCs, compared to the performance of the best reported semitransparent OSCs, and options for further optimization are discussed. Flexible bandgap engineering is a crucial material science achievement that opens possibilities in the design of organic bulk heterojunctions for semitransparent photovoltaics. An additional feature of novel polymer:nonfullerene acceptor blends is efficient free‐charge‐carrier generation at small energetic offsets. These material properties are considered in conjunction with achievements in device physics and engineering of organic semitransparent solar cells.
