Working Principle
A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. Also known as a "photovoltaic cell," it is a photonic semiconductor thin film that generates electricity directly from sunlight. As long as it is exposed to light with a certain intensity, it can instantly output voltage and generate current if a circuit is connected. Solar panels (modules) only have the function of light-to-electricity conversion and cannot store the generated electricity. The generated electrical energy is stored in portable power stations.
