Performance of Greenhouse for Growth Promotionof a Plant with Supplemental LED Light Using Photovoltaic Power Generated by the See-Through Solar Cells
Abstract
To construct the technical foundation of the growth promotion of Pea plants using short-time irradiation of blue LED light in addition to the natural daylight, we designed the irradiation equipment that consisted of blue LED light and see-through solar cells. See-through solar cells are amorphous silicon solar cells capable of passing light (light transparency of 10%) while generating electricity as shown in Fig.1. The power generated by a solar cell was used for supplemental lighting system(Downs et. al.1957,Takano et. al 1996,Lin 2000).. The aim of this study was to obtain basic knowledge on efficient supplemental lighting to establish plant growth and to design the irradiation equipment that consisted of blue LED light that consisted of blue LED light and see-through solar cells.
