Researchers from Wuhan University of Technology in China have developed a polymer solar cell with 19.1% efficiency and remarkable stability by blending small-molecule acceptors into polymeric matrices. The incorporation of linearly packed small molecule acceptors disentangled polymeric chains, creating efficient pathways for charge transport and reducing degradation. The resulting devices retained 97% efficiency after 2,000 hours of operation in air, with an extrapolated lifetime exceeding 100,000 hours. This work provides a practical pathway towards commercialization of flexible organic photovoltaics, with various layers including a molybdenum trioxide hole transport layer and a buckminsterfullerene electron transport layer contributing to the cell's success.
