研究目的
Investigating the development of ITO-free organic solar cells and modules based on the non-fullerene material system PBDB-T:ITIC using Roll-to-Roll (R2R) and Sheet-to-Sheet (S2S) processing techniques under ambient conditions.
研究成果
The work demonstrates successful development of ITO-free PBDB-T:ITIC organic solar cells and modules using R2R and S2S processing techniques under ambient conditions, achieving a PCE of 5.5%. Encapsulation with barrier films having a WVTR in the 10-4 g/(m2day) range is crucial for long-term stability. The study represents a significant step towards industrial-scale production of OPV devices.
研究不足
The study highlights the sensitivity of OPV devices to oxygen and UV light, necessitating careful encapsulation. The performance of devices processed in ambient air is lower than those processed in inert conditions, indicating a need for further optimization of materials and processes.
