Smart agriculture using greenhouses is expected to be a solution to food shortages. However, smart agriculture uses machinery, which requires electricity. As a source of electric power, Organic Photovoltaics (OPV) are installed in greenhouses, and solar matching, in which crops are grown under the OPV, is expected to be utilized. However, there is concern that the transmittance of OPV may affect crop cultivation. In this study, we aim to realize solar matching by using wavelength conversion sheets to amplify light in the wavelength band that is effective for crops.
