Semi-transparent organic photovoltaics

• Organic photovoltaics, as an economical solar energy conversion technology, are considered to be an effective approach to address environmental issues and energy challenges. With the peak efficiency of OPV exceeding 20%, the research focus will shift from efficiency-oriented to commercialization-oriented in the near future. Translucent OPVs (STOPVs) are one of the most likely forms of OPVs to be commercialized, and have so far achieved power conversion efficiencies of over 14% with an average visible light transmittance of over 20%.
  

• Cheng Pei, Wang Jiayu and others from Sichuan University reviewed the study of translucent organic photovoltaics. The authors systematically summarize the device structure, working principles, and evaluation parameters of STOPV, and compare them with opaque OPV. Then, we propose a strategy to construct high-performance STOPVs by co-optimizing materials and devices.

  
  

  In addition, the authors summarize the method to achieve STOPV amplification from the perspective of minimizing electrode and interconnection resistance. Potential applications of STOPV in multifunctional windows, agricultural photovoltaics, and floating photovoltaics are also discussed. Finally, the authors highlight the main challenges and research directions that need to be addressed before the future commercialization of STOPV.
