Abstract
Plasma the fourth state of matter comprising of ions, electronsand neutrals can be used for surface engineering of materials, therebyincreasing their life. The modifications can be below or above thesurface. Most of these technologies are environment friendly and do notemit any pollutants. At FCIPT a lot of such technologies are developed andtransferred to industries. The presentation will focus on use of suchtechniques for solar applications.
