Résumé
In certain configurations, solar cells are operating under thermal stress, i.e. at temperatures far beyond those of the Standard TestConditions (STC, 25 °C) [1]. In space for near-the-sun missions [2] or in terrestrial photovoltaic -thermal [3] or -thermoelectric [4] or -CSP [5] hybrid systems, cells can reach temperatures from 150 °C up to more than 400 °C. New methodologies aiming at designing,fabricating and characterizing such components are required. The main unknownsare the physical properties of the materials involvedand the physical phenomena affecting the photovoltaic conversion performances of cells at such large temperatures.
