First, because 5-axis laser is narrow band, it is a key and difficult problem to obtain the uniform hardness of the complicated surface by laser quenching on a big surface.
The post-processors will be according to the material constraints to plan the path.
Accordingly, the material constraints are obtained by the CAD system which is installed in the NC system, i.e. the post-processors generate the tool path on the basis of CAD data [6].

Study on Nickle Oxide Thin Film as Buffering Layer in Photovoltaic Solar Cells Nanhai Suna, Yafei Renb Department of Electrical Engineering and Automation Louyang Institute of Science and Technology Luoyang, 471023, P.
Recently, nickeloxide(NiO) thin film has attracted considerable attention because it can be used as a p-type transparent conducting film, an active electrode in electrochromic devices, and resistance change material in resistance random access memory(RRAM) devices [7].
It is known that as a p-type semiconductor material, the resistivity of nickel oxide film depends on the concentration of cation (Ni) vacancies.
But deadly factor of 4-8 nm thick NiO solar cells is fill factor (FF), they all have poor FF, larger leakage current and deficient electron blocking capability maybe the key factors.
