Abstract:
In the present work, we describe our efforts to develop device quality
CuInSe2, films through low cost, simple and eco-friendly hybrid techniques. The
most important point to be highlighted here is that the method fully avoids the use
of poisonous gases such as H2Se/Se vapour. Instead, selenisation is achieved
through solid state reaction between amorphous selenium and polycrystalline
metal layers resulting in both binary and ternary selenides. Thin films of
amorphous selenium (a-Se) used for this is deposited using Chemical Bath
Deposition (CBD). CulnSe2 films are prepared through the selenisation process.
Another PV material, indium selenide (In2Se3) thin films are also prepared using
this process.
