Semiconductor photovoltaic effect and solar cells

Semiconductor photovoltaic effect and solar cells

Solar cells are the core components of photovoltaic power generation systems, which can directly convert light energy into electrical energy. The working principle and technological progress are summarized below. Silicon is one of the most abundant elements on the earth. After “purification” and “growth”, it becomes a crystalline semiconductor and is the basic material for

Several advantages of solar photovoltaic power generation

Several advantages of solar photovoltaic power generation

Solar energy is the energy produced by the continuous nuclear fusion reaction process inside the sun. The average solar irradiance (radiation intensity) in the earth’s orbit is 1367kw/m². The circumference of the earth’s equator is 40000km, so it can be calculated that the energy obtained by the earth can reach 173000Tw. The standard peak intensity

How to choose the electric light source in solar photovoltaic lighting

How to choose the electric light source in solar photovoltaic lighting

Among electric light sources, the most ideal light source for solar photovoltaic lighting in the future should be LED. In recent years, due to the rapid development of LED technology and the global energy shortage, the concept of “semiconductor green lighting” has been accepted by more and more people. In 2004, the National Semiconductor Lighting
