Solar energy uses sunlight to induce a flow of ________ between two wafers.

Question

Quizplus · Accepted Answer

Solar energy is converted to electrical energy through the use of photovoltaic cells. These cells consist of two wafers, usually made of silicon, that are treated with impurities to create a p-n junction. When sunlight hits the cell, photons knock electrons from the atoms in the semiconductor material, creating a flow of electrons between the two wafers. This flow of electrons is what produces an electric current, which can then be used to power devices. Therefore, the correct answer is D) electrons.
