Although the OPV device has many advantages, it is hard to produce energy on cloud or rainy days. For realize energy harvesting regardless of the weather, we have developed the liquid contact TENG integrated OPV hybrid cells. The hybrid cells have made possible to produce energy in a bifacial structure due to the transparent TENG, which does not affect the light absorption and the semi-transparent OPV. The current-energy production of hybrid cell was nearly zero (∼10-5 mA) when dust accumulated on the device surface, whereas the hybrid cell exhibited a self-cleaning effect about 70% recovery from 34 mA to 23 mA due to the high water repellency of TENG surface.
