Abstract

We demonstrate that power recycling is feasible by merging a large-area (30$\times$120 mm$^{2})$ OLED panel and a solar cell into each other. The power recycling efficiency of 0.152% is achieved under the illumination of one side-emitting white OLED at 2 450 cd/m$^{2}$ when the conversion efficiency of a reference solar cell is 4% and the distance between the OLED and solar cell is 1.5 mm. We have found that the power recycling efficiency is decreased under high brightness due to a decrease in the power efficiency of OLED and a loss of current induced by the resistance of a transparent electrode. We have also shown that local heat generation of the large-area OLED panel would be an issue for power recycling.
