第293回応用セラミックス研究所講演会

講師: Prof. Aron Walsh

講演テーマ: Emerging materials for solar energy: herzenbergite, kesterite, perovskite and beyond

 Abstract:
 There are a large variety of materials being developed for application in solar cells. The majority are based upon naturally occurring minerals (so-called solar mineralogy). The general procedure has been to take a multi-component system and tune the chemical composition to optimise optical absorption for the terrestrial solar spectrum. Other factors also determine whether a material can be practically employed in a photovoltaic or photoelectrochemical system, for example, the absolute band energies (work functions), defect physics, and chemical stability. I will discuss our recent progress into computing these performance descriptors from materials simulations [1-5], including advances in structure-property relationships in the kesterite (e.g. Cu2ZnSnS4) and perovskite (e.g. CsSnI3 and CH3NH3PbI3) families, in addition to the herzenbergite (SnS) system. New directions in the field, including the development of novel photoferroic materials, will also be addressed.
