USF inventors have proposed solar cells that have internal energy storage capacity such that the cells internally store energy when they are not exposed to light or when the energy consumed from the cells is less than the energy generated by the cells. The invention consists of the conducting polymer that is capable of storing energy generated within the cell. Unlike conventional solar cells, if no load is connected or if the consumed energy is less than the generated energy, the cells internally store the excess energy like a super-capacitor. The stored energy can be delivered to the load even in the dark and the cycle can be repeated by charging the cell with light again.
