These solar cells are made up of

Photovoltaic Cells and Systems | SpringerLink

Photovoltaic cells are current sources where the current generated by them changes with the solar irradiation (solar radiation received per unit of area). If we look at Fig. 2.5a we can see that the current is directly proportional to solar radiation received by the surface of the cell. And in Fig. 2.5b, it can be seen that the increase in temperature decreases the open
