Omani Bedouins' readiness to accept solar thermoelectric refrigeration systems
In this work, a portable solar thermoelectric refrigerator was built in order to help Bedouin people living in remote parts of Oman. The purpose of the study was to demonstrate the feasibility of the implementation of the fabricated solar thermoelectric refrigerator. To this end, a survey questionnaire was conducted in order to evaluate the willingness of the Bedouin to buy the designed unit. ...

Cu
2Te solar cells fabricated by printingCu2Te particles were synthesised by ball milling and then printed on an In2S3/TiO2/FTO–glass substrate, resulting in superstrate–structured solar cells. The as–prepared Cu2Te particles were amorphous, but their crystallinity was improved after annealing at 400–650°C. The Cu2Te particles annealed at 400°C, melted partially, and a completely melted Cu2Te film was obtained at annealing temperatures ...

Synthesis and photovoltaic properties of CuInS 2 /CdS quantum dots co-sensitised TiO 2 photo-anodes
The CuInS 2 and CdS quantum dots co-sensitised solar cells are successfully fabricated to improve the photovoltaic performance. The CuInS 2 quantum dots are adsorbed on the surface of TiO 2 nanoparticles by assembly linking technique, and then the CdS quantum dots are deposited by successive ionic layer absorption and reaction technique. The absorption intensity is obviously enhanced and ...

The effect of sponge liner on the performance of simple solar still
In conventional solar stills, a part of the radiation is reflected by the inner wall surfaces to the still components and the remaining energy is stored by itself. The main objectives of this experimental study are: 1) to utilise the energy available on the inner wall surfaces of a still by using sponge liner; 2) to find the optimum thickness of sponge liner. Two single-slope solar stills are ...

Stellio heliostat set to cut CSP tower costs by 20%
A new heliostat modeled on South African data is using a pentagonal reflector design, innovative construction techniques and smart software to boost the cost efficiency of tower plants. Heliostat fields typically contribute about 50% of the capital investment for CSP tower plants, according to a study by SBP Sonne, the German engineering firm which has developed the Stellio heliostat design. ...

Design, development and performance evaluation of latent heat storage foot warmers
In this paper, three PCM based foot warmers of cylindrical and rectangular in shape were designed, developed and fabricated to store solar energy during sunshine hours. The stored energy was utilised to warm the feet in the late evening to replace electric heaters. By trial experiment, it was found out that the surface temperature of the storage units of the foot warmer should be between ...

Design, development and experimental investigation of a solar tunnel dryer for drying mushroom
A solar tunnel dryer was designed and fabricated with locally available materials having the cross sectional area of the entire tunnel 5400 ? 1700 mm. The half of the nearly air tight tunnel base was used as the flat plate air heating solar collector and the remaining half as a dryer. The drying air temperature could be easily raised by some 6-10?C above the ambient temperature at an air velocity ...

Design and theoretical performance analysis of linear Fresnel reflector solar concentrator with a tubular absorber
A linear Fresnel reflector solar concentrator (LFRSC) system is used nowadays for operation at intermediate temperature ranges by using solar energy. Considerable attention is being paid to the design, fabrication and testing of solar concentrators. The performance of the system depends on the design parameters, mass flow rate, desired temperature difference, tracking accuracy, etc. In the ...

Tungsten trioxide nanostructured electrodes for organic dye sensitised solar cells
Tungsten trioxide (WO 3 ) nanospheres with diameter ranging from 10 nm to 500 nm were synthesised by a facile thermal oxidation process. By resistively heating metallic tungsten in oxygen atmosphere, WO 3 nanoparticles were produced in high yield. Optical, compositional, morphological and structural studies were performed by UV-VIS-NIR spectrophotometry, X-ray photoelectron spectroscopy ...
