A homojunction is a semiconductor interface that occurs between layers of similar semiconductor material, these materials have equal band gaps but typically have different doping. In most practical cases a homojunction occurs at the interface between an n-type (donor doped) and p-type (acceptor doped) semiconductor such as silicon, this is called ...

A homojunction is the region between an n-layer and a p-layer in a single material, photovoltaic cell. Solar cells that use crystalline silicon, for example, are examples of homojunction devices. In a homojunction cell, crystalline silicon is altered so that one side is p-type, dominated by positi... Found on http://www.daviddarling.info/encyclopedia/H/AE_homojunction.html
