Hybrid Photovoltaic-Piezoelectric Flexible Device for Energy Harvesting from Nature

摘要

Hybrid piezoelectric-photovoltaic devices have been developed which are capable of generating electricity from solar as well as wind and rain energy. A hybrid film has been developed by depositing organic photovoltaic cell based on P3HT and PCBM on a piezoelectric film under ambient room conditions and tested. The hybrid film produced an open circuit voltage (V_(oc)) of 0.45V and a short circuit current density (J_(sc)) of 0.43mA/cm~2 under solar simulator and a peak power of 85 μW when subjected to a turbulent wind speed up to 10m/sec (36km/hour) in a custom built wind tunnel.
