Abstract

New prospects in radiometric references have been introduced in 2003 by using induced junctions assembled in a particular trap arrangement and by accurately computing their internal deficiency with numerical models developed for photovoltaic cells. The claimed uncertainty, some tens of ppm, is ten times lower than the present ones. After a description of the device we present the first results confirming its abilities. We discuss the gain in uncertainty in two applications, the photometry and the pyrometry and we show the interest in this technology for disseminating radiometric references at the best level.
