Solar energy conversion apparatus including a housing portion, an energy absorbing portion, a fluid directing portion and a cover portion; the housing portion including a molded plastic pan member including a base section with upwardly extending spaced spacer sections, the pan member including outwardly...
Apparatus for concentration and conversion of solar energyThe present invention is directed to an apparatus for the collection and conversion of light energy including a collector element defining the shape of a pentagon, and a concentrator including a plurality of pentagon shaped reflector e...
referred to as theReaction Center (RC). The RCs trap the excitation energy using special photoactive pigment molecules, which perform theprimary photochemistrythat results in the formation of one positively and one negatively charged molecule, and thereby leads to the conversion of light energy into ...
Although, the solar energy and wind energy systems contribute significant amount of electrical energy, the complexity of electrical network system is still a challenge to smart grid. A smart grid is developed by using smart apparatus, equipment, components and elements. The smart grid behavior and ...
Solar thermal energy is quite different from the photovoltaic (PV) solar panels (capable of direct conversion of solar radiations into electricity). The solar thermal systems designed for the production of electrical energy are of two major types: (1) active solar thermal system and (2) passive...
Calibration of the testing apparatus was performed every time before measurement. As shown in Supplementary Fig. 6a, a heater was put on the top surface of the copper plate which is covered by a layer of polyurethane foam of 3 cm thick to avoid heat loss. The other part is the same ...
Solar energy is the most sustainable alternative to fossil fuels. The production of solar thermochemical fuels from water/carbon dioxide not only overcomes
One of the major limitations of BiVO4 for further improving the solar energy conversion efficiency is its bandgap (B2.5 eV), which fundamentally limits photon absorption. Considering that there are a substantial number of photons in the 2.0–2.5 eV region of the solar spectrum, a reduction in ...
1.A floating solar energy conversion and storage apparatus, comprising:a horizontally expansive heat storage chamber floating in a body of ambient water and confining a volume of solar heated water;a heat engine including an evaporator for vaporizing a working fluid therein, generating means for uti...
Solar batteries using semiconductors are well-known, as an apparatus for directly converting solar energy into electric energy. In these conventional solar batteries, light wavelengths ranging from 400 nm to 450 nm in the vicinity of blue light are converted into electric energy, that is, only a ...
