The main aim of this paper is to review different thin film deposition techniques and their significance in photovoltaic applications. Chemical methods for preparing thin films are currently attracting due to their relative affordability, simplicity, and suitability for large-area deposition.
Thin film deposition methods Thin film deposition is a technique for coating surfaces with very thin layers of material that range in thickness from a few nano meters to 100 µm, or just a few atoms. It can also be used to build up layers on top of already-deposited coatings.
This chapter has shown the potential of some materials and chemicals used in the manufacture of thin film PV solar cells and modules to be hazardous. These hazardous chemicals can pose serious health and environment concerns, if proper cautions are not taken.
One key deposition method used in III–V thin film solar cell fabrication is metalorganic chemical vapor deposition (MOCVD), also called metalorganic vapor-phase epitaxy (MOVPE). Metal–organic CVD (MOCVD) is a CVD process for growing epitaxial films and is done by flowing precursor gases over the substrate.
Another way to minimize wastes generated during the fabrication of thin film solar cells and modules is reducing the amounts of toxic elements. For example, the possibility of reducing the quantity of toxic cadmium in the synthesis of CdS thin films, which plays the role of the buffer layer in CdTe and CIS solar cells has been investigated.
Film growth may occur through ion-by-ion condensation of the materials on the substrates, depending on the deposition circumstances. Thin film deposition can be influenced by various parameters such as PH, temperature, deposition time etc are also described in the present article.
