CISSY_XPS_UPSX-rays interact with matter  through photoabsorption, Compton scattering, and Rayleigh scattering. The strength of these interactions depend on the energy of the X-rays and the elemental composition of the material  This SOPHIA webinar introduces two powerful spectroscopic tools to investigate solar cell surfaces and interfaces.

Crystalline silicon (c-Si) wafers  is continuing to dominate the field of photovoltaics (PV). The material processed in cells and assembled into modules is reaching its limits both in terms of cost and conversion efficiency concepts. New approaches need to be proposed

A lot of exciting ideas are followed by scientists and researchers all around the world on advanced photovoltaics searching for new solution in photoconversion, light trapping and novel collecting structures  the so called “field of dreams where the research concepts and technology require the PV researchers’s creativity,  patience and funding to prove or develop concepts”.

Focused ion beam (FIB), is a well established technique used particularly in the semiconductor industry, materials science and  biological field for specific analysis, deposition, and ablation of materials can   represent a very useful “ab inizio” technique to prove in very short time new  concepts on advanced photovoltaics  before making investment in their further development and searching for cost effective solution.
