Several generations of new optics that approach the thermodynamic limit to concentration and optical tolerance, and have been tailored to the exigencies of the latest generations of concentrator solar cells, will be presented, some of which already comprise megawatt-scale installations. In addition, experimental results from novel localized irradiation probes that use ultra-intense concentrated sunlight for investigating concentrator solar cells will be reviewed. The findings include elucidating cell solid-state properties that are of value in designing future generations of higher-efficiency solar converters.</font></p><p class="MsoNormal" style="margin-right: -0.45pt; text-align: justify; "><span class="Apple-style-span" style="font-family: Arial; ">More information on Professor Gordon's research can be found <a href="http://bidr.bgu.ac.il/BIDR/research/staff/gordon/gordon.html">here</a>.</span></p><div style="text-align: justify;"><font class="Apple-style-span" face="Arial"></font></div></body></html>
