Do you know what a solar cell is? Well, it is a device converting the solar energy straight into the electrical energy. Previously, it has been observed that, when the solar rays fall of into the thin wafer of the selenium, the electricity will then be generated. On the other hand, a solar cell being made up of selenium wafer could convert about 0.7% of the solar energy into the electrical energy, which is definitely a small output and so, impracticable for making up electricity.
Moreover, the first solar cell, which is made up from the year 1954 can be converted for something like 1% of the solar energy incident into the electricity. Well, for the modern solar cells, most of them are made from the semimetal silicon could have the efficiency of about 25%. Usually, silicon is available and somewhat eco-friendly.
Apart from those, the usual solar cell only consist of 2 by 2 cm. sq. of the pure silicon piece and is able to produce like 0.7 watt of electricity with 10% of efficiency. The electricity it can produce is very little, yet for you to get a large amount of it, then you could connect the solar cells into a series. This type of arrangement will be known as the solar panel.
Advantages of Solar Cell:
- The advantage that you could take for the solar cells is that, it provides an eco-friendly milieu.
- Another thing is that, it could be used anywhere for being the self-generating source of electricity.
Limitations of Solar Cell:
- The first thing is that, there is only a limited availability of special grade silicon for making solar cells.
- The connecting material used is silver and primarily costly.
- The current being produced by the solar cells is definitely a direct current and it needs to be converted into the alternative current or the AC for some sort of devices. It actually needs you to spend a good amount of money, yet there would be a great loss of the efficiency.
- The conventional storing method of the solar energy for the storage batteries is inefficient.
Uses of Solar Cell:
Its uses could be great for the transmission of wireless radio, television, artificial satellites, traffic signals, calculators, watches, research centers and even with those solar cars.
