Answer:
Photovoltaic cell or solar cells
Explanation:
Solar cells are cells that converts light energy from the sun into electrical energy for use in appliances. Light energy impinges on these cells, the photons of light causes electrons in the solar cells to move thereby resulting in the production of electricity in the cells.
