Selenization of CIS Nanoparticles
Researchers at Purdue University have developed a photovoltaic printing technology utilizing CuInS2 nanocrystal inks, allowing for the creation of CIGS at the molecular level. This is beneficial because smaller particles will lead to a more densely packed nanoparticle film, and it allows for the fabrication of the film with solely the CuInS2 nanoparticle or a mixture of the CuInS2 nanoparticle with other CIGS materials, such as CuIn(Sy,Se1-y)2, CuGaS2, CuGa(Sy,Se1-y)2, Cu(InGa1-x)S2, and Cu(InxGa1-x)(Sy,Se1-y)2. This process is also safe, less expensive, and has a high production yield.
