Lead halide perovskites have emerged as successful optoelectronic materials with high photovoltaic power conversion efficiencies and low material cost. However, substantial challenges remain in the scalability, stability and fundamental understanding of the materials. Here we present the application of radiative thermal annealing, an easily scalable processing method for synthesizing formamidin...

In this study, thermodynamic and economic analysis of a photovoltaic electricity generation system (PVEGS) with and without self-cleaning panels is reported. In the first part, thermodynamic analyses are used to characterize the performance of the system. In the second part, the economic comparison of photovoltaic electricity generation with and without self-cleaning panels is carried out for a...

This paper presents a thermoeconomic analysis of polygeneration system based on solar-assisted desiccant cooling. The overall plant layout supplies electricity, space heating and cooling, domestic hot water, freshwater for residential building. combines photovoltaic/thermal collectors, photovoltaic panels, biomass boiler coupled with reverse osmosis air conditioning. was modeled in TRNSYS simul...

A portable Thermal-Infrared Transfer Radiometer (TXR) has been developed for use in intercomparisons and scale verifications of sources used to calibrate thermal-infrared (TIR) channels of the National Aeronautics and Space Administration’s (NASA’s) Earth Observing System (EOS) flight instruments. The TXR is designed to measure the radiance temperature of large area blackbody sources in cryogen...

the increase of cell temperature with increased irradiance is probably the mostsignificant disadvantage of using photovoltaic modules equipped with booster reflectors. the aimof this study is to investigate the possibility of improving the performance of a photovoltaic waterpumping system by using a booster reflector and to keep the temperature of pv panels at a lowlevel by cooling pv panels wi...

Energy consumption is steadily increasing with the ever-growing population, leading to a rise in global warming. Building energy one of major sources warming, which can be controlled renewable installations. This paper deals an advanced evacuated hybrid solar photovoltaic–thermal collector (PVT) for simultaneous production electricity and domestic hot water (DHW) lower carbon emissions. Most PV...
