Answer:
Photovoltaic cells are devices that use semiconductors to produce electricity from solar energy.
Step-by-step explanation:
Photovoltaic cells, also known as solar cells, are made of materials such as silicon or germanium that can absorb sunlight and convert it into electricity. They are commonly used in solar panels, which are mounted on rooftops or other structures to capture sunlight and generate electricity for homes, businesses, and other applications.
Flash bulbs, fuel cells, and photometers are all unrelated to the production of electricity from solar energy. Flash bulbs are used in photography to produce a burst of light, fuel cells are devices that generate electricity through the chemical reaction of a fuel and an oxidant, and photometers are instruments used to measure the intensity of light.
