ABSTRACT Gas Technology Institute (GTI), together with its partners University of California at Merced (UC Merced) and MicroLink Devices Inc. (MicroLink) are developing a full spectrum solar energy collection system to deliver variable electricity and on-demand heat. The technology uses secondary optics in a solar receiver to achieve high efficiency at high temperature, collects heat in particles for low fire danger, stores heat in particles instead of molten salt for low cost, and uses double junction (2J) photovoltaic (PV) cells with backside infrared (IR) reflectors on the secondary optical element to raise exergy efficiency. The overall goal is to deliver enhancement to established trough technology while exceeding the heliostat power tower molten salt temperature limit. The use of inert particles for heat transfer may make parabolic troughs safer near population centers and may be valuable for industrial facilities. INTRODUCTION High utilization of solar energy is an important component for future energy needs that will ensure U.S. energy independence with a corresponding low environmental impact [1]. Solar energy is available at no cost, but efficient collection, storage, and use of this energy in an economical way remains a challenge. Current examples of energy conversion technologies include photovoltaic (PV), concentrated photovoltaics (CPV), co
