The key feature of conventional Photovoltaic PV (solar) cells is the PN junction. In the PN junction solar cell, sunlight provides sufficient energy to the free electrons in the n region to allow them to cross the depletion region and combine with holes in the p region. This energy creates a potential difference (voltage) across the cell.
A diode is a unidirectional semiconductor device which only passes current in one direction (forward bias i.e. Anode connected to the positive terminal and cathode is connected to the negative terminal). It blocks the current flow in the opposite direction (reverse bias i.e. Anode to the -Ve terminal and Cathode to the +Ve terminal). They are made off semiconductor …
