Abstract
It is shown how to efficiently convert solar into electrical energy, taking advantage
of laser amplification and intra-cavity use of a low-efficiency
converter. The latter may consist of a low-efficiency transparent
photovoltaic cell or a thermoelectric cell integrated into a metallic
laser-cavity mirror, constituting a minor intra-cavity loss for the
laser operation. The overall power-conversion efficiency is derived
and discussed for a variety of current solid-state laser materials. It
is shown that power-conversion efficiencies comparable with commercial
silicon photovoltaic cells are obtained with current laser
materials.
