Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a photovoltaic power supply system. Background technique [0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect of the semiconductor interface. It is mainly composed of solar panels (components), controllers and inverters. The main components are composed of electronic components. After the solar cells are packaged and protected in series, a large-area solar cell module can be formed, and then a photovoltaic power generation device is formed by cooperating with power controllers and other components. All electrons are absorbed, and the energy absorbed by the electrons is large enough to overcome the Coulomb force inside the metal atom to do work, escape from the metal surface, and become photoelectrons. Silicon atoms have 4 outer electrons. If 5 electrons are mixed in...
