Conexiones en serie y en paralelo de las placas solares - voltaje en circuito abierto y corriente en circuito pequeño

Principle

Series or parallel connection of solar cells can be used to change voltage and current and to adjust them to the consumer's needs. The short-circuit current of solar cells is proportional to the irradiance, while their voltage output is nearly independent of it.

Benefits

  • No ...

Conversion of light into motion with a solar cell

Principle

With the aid of a solar cell, solar energy can be converted into electrical energy. This is a very important form of energy, not only for the household but also for industrial applications, since it can be easily converted into other forms of energy, e.g. heat, light, or ...

The solar cell as a diode

Principle

A solar cell consists of a p-doped layer and of an n-doped layer. Under the influence of light, free charge carriers are generated. These charge carriers are pushed outwards by the electric field, thus generating voltage. Due to this layout, the orientation of the voltage is ...
