Looking at NREL photovoltaic technology cell efficiency chart 2020( Examples :Multi-Junction, Sigle crystal, Multicrystalline, heterostructures, CIGS,
Perovskite, Organic,……etc ), each student should choose one technology different than the other student, to write an essays with minimum 1600
word explaining the methods and the tools used to achieve that cell technology you can add literature review, picture of tools, drawing, reference.
Examples of the tools ( Epitaxy-MBE, MOCVD, Dry etching, Thin film deposition , Plasma Enhanced Chemical Vapour Depositiuon and Rapit Thermal
Processing, Furnaces).
