Heterojuntions

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 p-n junctions are considered that consists of the same semiconductor materials with the same bandgap energy. This is called a homo-junction. In this video you will learn about a p-n junction consisting of two different semiconductor materials: the heterojunction.
