Abstract Solar stills utilization has received great interest in arid isolated regions. In this study, experimental approaches have been investigated to prove the impact of corrugated absorber shape on hemispherical solar still performance. Four geometric shapes including present flat, triangular, semi-circular, square forms were tested for absorber. Five distillers fabricated and tested. The f...

Plasmonic solar absorber holds great potential in solar-powered steam generation due to its resonant absorption, rapid photo-to-heat conversion, and localized heating impact. However, expanding the absorption bandwidth of plasmonic nanoparticles is challenging. Here, we produce flexible cellulose papers (PCPs) with broadband by filling nanogaps (between nanofibrils) commercially available (CPs)...

In this paper we present an optical simulation of light management in Cu(In,Ga)Se2 thin-film solar cells with reduced absorber layer thickness, with the goal of absorption enhancement in the absorber layer. The light management was achieved by texturing of the substrate layer, and the conformal growth of all the following layers was assumed. Two texturing shapes have been explored: triangular a...

The CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) and the EURECA (European Underground Rare Event Calorimeter Array) experiments are direct dark matter search experiments where cryogenic detectors are used to detect spin-independent, coherent WIMP (Weakly Interacting Massive Particle)-nucleon scattering events by means of the recoil energy. The cryogenic detectors use a...

An epithermal neutron camera based on energy-filtered imaging with gas electron multipliers was developed. Epithermal neutron imaging is achievable without time-of-flight detection of neutrons by using a resonance filter and a thermal neutron absorber. This technique is applicable to compact accelerator-based neutron sources. Blurring of epithermal neutron images caused by neutron scattering in...

Recent studies on increasing the thermal-hydrodynamic efficiency of solar air collectors have been carried out installation barriers various shapes surface absorber, and this method ensures a significant increase in energy collector. The transfer flow washing absorber from laminar state to an accelerated lumped is by installing obstacles. Installation main factor heat prolongs time barrier coll...

Solar cookers are aimed at reducing pollution and desertification in the developing world. However, they are often disregarded as they do not give users the ability to cook after daylight hours. The Wilson solar cooker is a solar cooker designed to address this problem by converting solar energy and storing that energy as heat in the form of molten salt (lithium nitrate). This thesis involved r...

Utilization of solar energy can be found in various domestic and industrial applications. The performance of any solar collector is largely affected by various parameters such as glazing, absorber plate, top covers, and heating pipes. Technology improvements have brought us another method for conversion of solar energy to direct electricity using solar photovoltaic system. Utilization and extra...
