Indoor PF2:ITIC organic solar cells with enhanced blue-light harvesting and high voltage

Key Points

• The aim is to enhance blue-light harvesting and increase voltage output in indoor organic solar cells.
• Optimized PF2:ITIC blends used to create devices tested under 1000 lx LED illumination.
• Photovoltaic performance evaluated for power conversion efficiency (PCE) and open-circuit voltage (V OC).
• Scanning Microscopy Imaging (sMIM) applied to assess nanoscale morphology of organic layers.
• The optimized device achieves a power conversion efficiency (PCE) of 12%.
• Open-circuit voltage (V OC) reached 0.72 V under 1000 lx illumination.
• sMIM reveals improved nanoscale morphology in organic layers.
