The effect of a beam of light on a semiconductor is quite different from that of other objects. There are a lot of free electrons in
Objects can be roughly divided into conductors, semiconductors and insulators according to their conductivity. Let’s talk about semiconductors in detail below. Pure semiconductor materials are
On the plane where the upper boundary of the atmosphere is perpendicular to the light, the solar irradiance is basically a constant, but on the
In order to describe solar energy quantitatively, some concepts need to be introduced. When the earth is located at the average distance between the sun
It is generally believed that the sun is a huge gas mass under high temperature and high pressure, which can be divided into 6 regions
1. Human activities and solar radiant energy Everything grows by the sun. The energy needed for human production and life, such as oil, coal, wind energy, ocean tidal
