The principle of power generation by dye-sensitized solar cells has been known since the pioneering work of Gerischer and Tributsch in the sixties and seventies, wherein the introduction of Nano porous electrodes in 1990 by Grätzel improved the conversion efficiencies of the cell to about 7%. In this paper, we will construct a DSSC's small scale prototype. It will clearly picture how do DSSC's work...
In Concentrated Solar Power (CSP) application, top coatings are of tremendous importance as a way to protect the reflective layers form degradation and conserve the efficiency and durability of the mirrors. The choice of Al2O3 as a top-protective coating for CSP reflectors is based on its high stability, hardness and transparency. In this study, high quality and stable CSP first-surface silvered thick...
Desert areas are considered to be the most suitable sites for CSP power plant installations due to their high irradiance, principally the direct normal irradiance (DNI), as well as the flat land scape and lower population densities. However, CSP reflector components are exposed to very harsh weather conditions in desert areas, such as wind storms, strong irradiation flux, scarcity of water needed...
This work consists on the improvement of first surface silvered thick glass mirrors. Several types of CSP mirrors based on different Physical Vapor Deposition techniques (PVD) and the presence or absence of the copper protective back layer were prepared: ([Ag Sputtered], [Ag Evaporated], [Cu Sputtered-Ag Evaporated], [Cu Evaporated-Ag Sputtered], [Cu Evaporated-Ag Evaporated] and [Cu Sputtered-Ag...
