CO2 High Temp Cycle Nanotechnology
Photovoltaics – Solar Thermal (CSP)• Photovoltaic systems use solar radiation directly to convert light(photons) into direct electrical current (DC)• Thermal systems use concentrating optics, lenses or usually mirrors to concentrate the light (heat) onto a receiver to heat a fluid (e.g. water) to high temperatures and the fluid powers a heat engine (turbine) connected to an electrical generator.
Photovoltaics Technologies• Silicon Based Cells• Thin Film
Concentrated Solar Power (Thermal)• Concentrating solar power is one of the most ancient ways of using solar energy.• First Solar High Temp. Concentrator was built In Egypt 1912, parabolic solar collectors, were developed by a Philadelphia inventor named Frank Shuman• First Commercial Power Plants Inaugurated In California Mojave Desert 1984 by the Israeli company LUZ

Aora Solar• Commercial Brayton Cycle Power• AORA′ s solar thermal plants are based on the process of a conventional gas powered micro turbine• The combustion chamber was modified to connect a high temperature solar receiver• AORA′ s CSP plants are capable to operate on hybrid mode, using several types of fuels, like biogas, natural gas or other fossil fuels.
?WHY SOLAR BRAYTON CYCLE Thermodynamics Basics: Carnot• The maximum theoretic efficiency η is defined to be:where• W is the work done by the system• QH is the heat put into the system• TC is the absolute temperature of the cold reservoir• TH is the absolute temperature of the hot reservoir
