Application

Currently there is research into developing solar cells using the nitride based semiconductors. Using one or more alloys of indium gallium nitride (InGaN), an optical match to the solar spectrum can be achieved. The bandgap of InN allows a wavelengths as long as 1900 nm to be utilized. However, there are many difficulties to be overcome if such solar cells are to become a commercial reality: p-type doping of InN and indium-rich InGaN is one of the biggest challenges. Heteroepitaxial growth of InN with other nitrides (GaN, AlN) has proved to be difficult.
