Reduce environmental pollution. The importance of promoting the use of solar cells is to reduce the use of fossil fuels, thereby reducing environmental pollution. Solar cells are optoelectronic semiconductor sheets that use sunlight to directly produce electricity. They are also called “solar chips” or “photovoltaic cells”. "As long as it is illuminated by light that meets certain lighting conditions, it can instantly produce voltage and generate current if there is a loop.
1. Universal. The sun shines on the earth, there is no limit, it is everywhere, it can be directly developed and used, and there is no need for mining and transportation
2. . Harmless. The development and use of solar energy will not pollute the environment.elm. The energy of solar radiation that reaches the Earth's surface each year is approximately equivalent to 130,000 billion tons of standard coal, and its total amount constitutes the largest energy that can be developed in the world.
4. Long duration. Based on estimates of the rate of nuclear energy produced by the sun at the start of the 21st century, hydrogen reserves are sufficient to last tens of billions of years, while the Earth's lifespan is approximately billions of years. we can say that the energy of the sun is inexhaustible.
