Routes to energy conversion with functional oxide films and nanostructures, a short review

Residual Energy Harvesting from Light Transients Using Hematite as an Intrinsic Photocapacitor in a Symmetrical Cell

“…Ambient energy harvesting technologies have emerged for mechanical vibrations (based on piezoelectrics) and variations of temperature with time (based on pyroelectrics), as well as for static light energy. , Often the harvesting mechanism is based on a cycle of high/low mechanical pressure or high/low temperature applied in an alternating fashion to create ac power output that is often rectified and stored in a capacitor. Similarly, for light energy harvesting a light-on/light-off cycle could be imagined.…”
