The illuminated depletion region part one

This video is part of the FREE online course PV1x Photovoltaic Energy Conversion, developed by Delft University of Technology. PV1x is part of the Solar Energy Engineering MicroMasters program.Let’s discuss the most important part of the p-n junction behaviour for solar cell operation: the p-n junction under illumination. In this video you will learn how illumination influences the concentration of charge carriers, the built-in voltage and the width of the depletion region.
