Basic research needs and opportunities at the solid-gas interface

Abstract

S-G reactions that may occur at surfaces of devices exposed to the normal solar environment are of major concern in solar technology. It becomes necessary to know how the properties of a particular component layer are affected by the manufacturing environment (air, vacuum etc.) and especially to know how the overall operation of the device is influenced by the cumulative effect of various surface reactions. This problem is of special importance in solar applications because of the frequent use of multilayer technology and the long lifetime requirements for components. There are a number of important chemical reactions which involve photoconversion and/or photocatalysis. In these processes, S-G interfaces occur on the catalysts and their support materials. Major research needs include a detailed understanding of semiconductor surfaces with and without chemisorbed species, understanding of the photoconversion and photocatalysis mechanisms, effects of sensitizers, understanding of spill-over phenomena, theoretical calculations and new experimental methods for analysis of the S-G interface under ambient pressure. In both thermal conversion and catalytic conversion systems the transfer of energy occurring at S-G interfaces is very important. The problem is not simple, especially under high UV fluxes and on non-metallic systems. It is conceivable that useful resonant energy transfers  More>>
