1.1 Classification of solar cell materials In order to make effective use of solar energy, we must first find materials for making solar cells. The
1.1 Photovoltaic effect “Photovoltaic effect” is abbreviated as “photovoltaic effect.” Photovoltaic effect refers to the phenomenon that light produces a potential difference between different parts
1.1 Volt-ampere characteristics of semiconductor diodes The characteristic of the diode is mainly unidirectional conductivity, which has been explained in the characteristic of PN junction.
1.1 Band structure and photoconductivity of semiconductors 1.1.1 Band structure of semiconductors No matter how electrons and holes move, they must have many states of
1.1 Characteristics of PN junctionEveryone knows that although there are a lot of free electrons in a conductor, the conductor itself is not charged. Similarly,
1.1 The mechanism of semiconductor and metal conductor conduction The term “semiconductor” is relative to “conductor”. Objects with high conductivity are called conductors; objects that
1.1 The concentration of free electrons and free electronsWhy do metal materials have the ability to conduct electricity? The answer can be obtained from the
What is solar radiation intensity and solar radiation energy conversion? 1.1 Solar radiation intensity The solar radiation energy projected vertically onto a unit area in
1.1 Ground radiation While absorbing solar radiation, the earth’s surface transmits most of its energy to the atmosphere in the form of radiation. The way
