DOIAbstract
In this chapter we present basic concepts which are relevant to link the results obtained from ellipsometry data analysis with fundamental properties of semiconductors for photovoltaic applications. The linear optical properties of semiconductors are best discussed in terms of the relationship between the dielectric function ε and the band structure.The authors thank the Spanish Ministry of Economy and Competitiveness (MINECO) for funding through grants CSD2010-00044, MAT2015-70850-P, and the “Severo Ochoa” Programme for Centres of Excellence in R&D (SEV- 2015-0496).Peer reviewe
