Explain the Principle of Working of Solar Cells Made of Semiconductor

Thus when solar radiations fall in a solar cell, it converts solar energy into electrical energy. A lead storage battery is connected in the circuit which gets charged and can be used as and when desired.

The power generated by a single solar cell is very low. A single solar cell with an area of 4 cm2 has an output voltage of about 0.4-0.5 volts at 60 mill amperes of current.

Therefore, a large number of solar cells are mounted together to generate appreciable electrical power. The solar cells are arranged in series to form solar panels.

Solar panel cells are mostly used in space satellites which remain in outer space for many years.

The space satellite contains solar panels which convert sunlight energy into electrical energy and thus electrical energy is used by satellite to operate various functions.
