A1.)A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by photvoltaic effect, which is a physical and chemical phenomenon.It is a form of photoelectric cell, whhich is a device whose electrical characteristics, such as current , voltage, or resistance vary when exposed to light.
Individual solar cell devices can be combined to form modules, otherwise known as solar panels. Even a basic a single junction silicon solar cell can produce a maximum open-circuit voltage of approximately 0.5 to 0.6 volts.
A2) Uses of solar cell
1:-Solar cells are used to give power to man-made satellites in space.
2:-Solar cells are also used to give power to water pumps and street lights in remote places where there is no electricity.
3.Solar cells produce DC, but you can buy PV panels with built-in microinverters, which allow PV modules to produce AC directly. If you use DC PV panels (without internal microinverters), then you would need to have an external inverter to convert the DC power to AC power if you want to attach to an AC power grid.
4. The one disadvantage of a solar cell is the high initial cost for material and installation and long ROI
