The role of the pn junction of photovoltaic panels
A PN junction is simply the boundary formed when a P-type and an N-type semiconductor are joined together, creating a depletion region and a built-in electric field that separates charges. This internal electric field is what makes solar cells generate electricity. The cell's function relies on a. . The magic happens when you bring some n-type material next to some p-type material, and create what's called a p-n junction. This video explains the PN junction, depletion region, electron–hole recombination, and the photovoltaic effect in a simple, visual, and easy-to-understand way. Consider a semiconductor. .
