WebHeterojunctions. A bulk heterojunction (BHJ) organic solar cell (Figure 3) has essentially the same structure as a single-layer LED, except that the active layer is a mixture of an electron acceptor and an electron donor.

The two semiconductors are not necessarily the same, e.g. 1 could be AlGaAs and 2 A heterojunction is an interface between two layers or regions of dissimilar semiconductors. These semiconducting materials have unequal band gaps as opposed to a homojunction. It is often advantageous to engineer the electronic energy bands in many solid-state device applications, including semiconductor lasers, solar cells and transistors. The combination of multiple heterojunctions together in a device is called a heterostructure, although the two terms are com… eastern shires purchasing
