A heterojunction is an interface that occurs between two layers or regions of dissimilar crystalline semiconductors.

These semiconducting materials have unequal band gaps as opposed to a homojunction.

Silicon heterojunction technology (Si-HJT) is a popular topic in crystalline silicon photovoltaic as it allows for solar cells with energy conversion efficiencies above 20 %, even at industrial production level. These solar cells consist of thin amorphous silicon layers on monocrystalline silicon wafers.

As of mid-2016, heterojunction cells are still predominantly in research and pilot stages and are not deployed commercially on a large scale anywhere in the world.
