Water distillation techniques are good ways to deal with shortage of freshwater. One these is solar water still which can be used remove harmful substances from contaminated by using free energy make it safe drink before it. The most important obstacle a the modest amount that produced. Therefore,there need improve performance stills so more productivity made. In rural areas, there aren't enoug...

   In this manuscript, a solar cavity packed with thermoelectric generator modules is investigated numerically. The hot plate of TEG modules make the inner surface of the cube, and the cold plate is outside of the cavity, under natural convection. The TEG modules are electrically in series. The solution algorithm using the equations of heat transfer and generated power of TEG modules is d...

PAPER Haussener et al. Simulations of the irradiation and temperature dependence of the effi ciency of tandem photoelectrochemical water-splitting systems Simulations of the irradiation and temperature dependence of the efficiency of tandem photoelectrochemical water-splitting systems † The instantaneous efficiency of an operating photoelectrochemical solar-fuel-generator system is a complicate...

This paper develops techniques to improve the concept of ‘solar envelopes’ and tests them on the Milan Trade Fair site, one of the largest real estate developments currently being carried out in Europe. The techniques are based on the image processing of very simple raster models of urban forms, called Digital Elevation Models (DEMs). Two questions are asked: could the new techniques simplify s...

Solar energy is the most important green source that may be used to address problems caused by conventional sources. The research in this paper aims evaluate solar potential of M'Sila, an Algerian internal region, and determine which technology, among those currently available on market, adequate for harnessing electricity production (PV CSP). This assessment was based data (daily temperature d...

The primary objective of desalination research is the development of a way to produce fresh water at lower cost. The present study investigated two freshwater production methods of Reverse Osmosis (RO) and Multi-Effect Humidification (MEH) (artificial distillation), and analyzed them from an economic standpoint, and subsequently pointed out the important and effective factors in decreasing salt...

The ability of living organisms to survive extraterrestrial conditions has implications for the origins of life in the solar system. We have therefore studied the survival of viruses, bacteria, yeast, and fungi under simulated Martian conditions. The environment on Mars was simulated by low temperature, proton irradiation, ultraviolet irradiation, and simulated Martian atmosphere (CO2 95.46%,...

The high molar absorption coefficient organic D-π-A dye C220 exhibits more than 6% certified electric power conversion efficiency at AM 1.5G solar irradiation (100 mW cm(-2)) in a solid-state dye-sensitized solar cell using 2,2',7,7'-tetrakis(N,N-dimethoxyphenylamine)-9,9'-spirobifluorene (spiro-MeOTAD) as the organic hole-transporting material. This contributes to a new record (6.08% by NREL) ...

This study determines the effects of annealing treatment on the structure and the optical and electronic behaviors of the mixed (FAPbI₃)1-x(MAPbBr₃)x perovskite system. The experimental results reveal that (FAPbI₃)1-x(MAPbBr₃)x (x ~ 0.2) is an effective light-absorbing material for use in inverted planar perovskite solar cells owing to its large absorbance and tunable band gap. Therefore, good ...

Photoelectrochemical (PEC) conversion of solar light into chemical fuels is one of the most promising solutions to the challenge of sustainable energy. Graphitic carbon (IV) nitride polymer (g-CN) is an interesting sustainable photocathode material due to low-cost, visible-light sensitivity, and chemical stability up to 500 °C in air. However, grain boundary effects and limited active sites gre...
