摘要:

Because the visible and the infrared (IR) regions take up 47% and 51% of the   energy in the solar spectrum (AM 1.5G standard), respectively, utilizing the   visible light for plant growth and the IR light for power generation is potentially extremely exciting. IR-absorbing organic semiconductors, with  localized IR absorption and visible-light transmittance, would be promising materials for this purpose. Here, flexible transparent organic photovoltaics (TOPVs) based on IR-absorbing organic materials were proposed, which can be a   simple, low-cost, and promising way to utilize the IR light for electricity generation, and the penetrated visible light will be utilized for photosynthesis in plants. A power-conversion efficiency of 10% with an average visible transmittance of 34% was achieved for TOPV devices. Meanwhile, the side-by-side comparison showed that plants grown under the TOPVs filtered light, and those under normal sunlight yielded very similar results. These outcomes demonstrated the results from TOPV devices beyond simple photovoltaic applications.
