When the electric power, coal, petroleum and other non-renewable energy dries up, the energy problem has become a bottleneck restricting the development of international economy, more and more countries began to implement the "sunshine project", to develop solar energy resources, seek the momentum of economic development, the huge potential in the international pv market, driven by solar cell manufacturing rushed to invest heavily in various countries, expand production, The market for solar cells is huge. Solar cells are devices that directly convert light energy into electricity through the photoelectric or photochemical effect. As long as it is illuminated, it can output voltage and current instantly, which is called solar photovoltaic in physics. Thin-film solar cells working with photoelectric effect are the mainstream, while wet solar cells working with photochemical effect are still in the embryonic stage.
