To take advantage of solar energy, it is necessary to subject it to a capture and conversion process through the use of specialized devices such as solar cells (SCs) and optical concentrators, among others [3]. The principle operation of the devices consists of its simple exposure to solar ...
Recently, a combination using both wind turbines and a fuel cell has been elaborated for a drive train in Germany [20]. The water/electrolysis is powered by wind energy, which has great potential and can be used in rail transportation Another work on the potential of wind energy development ...
An epitaxial silicon solar cell structure is grown on a monocrystalline silicon substrate. The structure is then bonded to a glass superstrate. The silicon substrate is then removed. Most simply, the removal of the silicon substrate can be effected by controlled etching, in which case the ...
which operates on the reverse principle of an absorption-type refrigerator. The evaporator is arranged near the roof, covered by insulating glazing. The boiler in the circuit can be heated by an oil or gas burner or by an immersion heater or by a solar cell-fed battery. Pref. the heat ...
News Solar Cell + Liquid Battery System Achieves Record Efficiency October 05, 2018 by Paul Shepard The growing use of solar power has hit a wall in some locations: At night, or on a cloudy day, electric utilities with heavy dependence on solar must switch to an alternative source like ...
The basic principle of the SH is that solar irradiance is absorbed by the solar absorptive materials and then be transferred into heat for the end-user. The key to achieve SH is that the material needs to have high solar absorptivity, and there are a variety of solar absorptive materials fo...
Reducing the transmission loss for below-gap photons is a straightforward way to break the limit of the energy-conversion efficiency of solar cells (SCs). The up-conversion of below-gap photons is very promising for generating additional photocurrent. He
The system operates on the principle of reducing nitrate (NO3-) in water to produce NH3usingsolar energy. This method not only offers a more environmentally friendly alternative to the conventional Haber-Bosch process, which heavily relies onfossil fuels, but also opens up opportunities for the sy...
This article covers the working principle, architecture, and uses of advanced multi-junction solar cells in achieving more efficiency.
