Firstly, let’s understand what a solar cell is. Simply put, it is a device that converts sunlight into electricity, through the photovoltaic effect. Sometimes, lots of solar cells are assembled to make solar modules, solar panels, or even photovoltaic arrays. Those solar cells that can generate electricity with a higher efficiency than the usual or conventional solar cells are called high efficiency solar cells. These are more efficient because of their electrical output per incident energy, that is, watt/watt. Constant research is going on, to increase the efficiency of solar cells.
