In addition, photovoltaic cells, also known as "solar chips" or "solar cells", are photoelectric semiconductor sheets that use sunlight to directly generate electricity. As long as it is illuminated by light, it can output voltage instantly and generate current when there is a loop. In physics, it is called solar photovoltaic (Photovoltaic, photo light, voltages volts, abbreviated as PV), or photovoltaic for short. A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. Thin-film solar cells that work on the photoelectric effect are the mainstream, while practical solar cells that work on the photochemical effect are still in their infancy.

Since the 1958s, artificial satellites launched by the United States have used solar cells as a source of energy. During the energy crisis in the 1970s, countries around the world were aware of the importance of energy development. The oil crisis occurred in 1973, and people began to transfer the application of solar cells to general livelihood purposes. In countries such as the United States, Japan, and Israel, a large number of solar energy devices have been used, and they are moving towards the goal of commercialization. Among these countries, the United States built the world's largest solar power plant in California in 1983, and its power generation capacity can reach as high as 16 megawatts. South Africa, Botswana, Namibia and other countries in southern Africa have also set up programs to encourage remote rural areas to install low-cost solar power generation systems. The most active country to promote solar power generation is Japan. In 1994, Japan implemented a subsidy and incentive method to promote the "mains parallel solar photovoltaic energy system" of 3,000 watts per household. In the first year, the government subsidizes 49% of the funds, and the subsequent subsidy decreases year by year. The "mains parallel solar photovoltaic energy system" uses solar cells to provide electric energy to the loads of the home when there is sufficient sunshine, and if there is excess electricity, it will be stored separately. When the power generation is insufficient or does not generate power, the required power will be provided by the power company. By 1996, 2,600 households in Japan had installed solar power generation systems, with a total installed capacity of 8 million watts. A year later, there were 9,400 installations, and the total installed capacity reached 32 megawatts. With the rising awareness of environmental protection and the government subsidy system, it is estimated that the demand for solar cells for residential use in Japan will also increase rapidly.
