Sustainable Energy Production Through Utilizing Hybrid Solar-Rain Cells

Ribwar Ahmadi fabricates and tests Silicon-based hybrid solar-rain cells to harvest the energy of sunlight and falling droplets of water simultaneously.

To transform different kinds of mechanical energy in the environment into electricity, a triboelectric nanogenerator (TENG) based on contact electrification and electrostatic induction has been developed. Recently, triboelectrification at the water/solid interfaces has been exploited to build a novel type of mechanical energy harvesters that shows promise for harvesting energy from ocean waves, tides, and rainwater in the environment.

In the Nano Device Fabrication Group, we have developed a small prototype of the hybrid solar-rain cell based on crystalline Silicon. The results indicate that Silicon by itself is capable of harvesting energy from the sun and falling droplets of water individually and simultaneously.

This project seeks to test the technology of hybrid solar-rain cells that has the potential to be upscaled.
