Cooling the air with sunlight
A firm has developed an evaporative cooler that has an integrated photovoltaic system isolated from the electrical network, which enables to refresh an area of ??approximately 200 square meters.
Finding a way to boost efficiency of CIGS solar cells
Researchers have revealed the structure of the buffer layer in a CIGS (copper-indium-gallium-selenide) solar cell at SPring8, the world’s largest third-generation synchrotron radiation facility. They found that the buffer layer was composed of two layers: an upper Zn(OH)2 layer and a lower Zn(S, O) layer. By removing the upper Zn(OH)2 layer, the solar conversion efficiency was doubled.

Smart chip tells you how healthy your battery is
A smart chip that can tell you how healthy is your battery and if it is safe for use, has been developed by researchers.
Promising new prototype of battery
An alternative technology to Li-ion has been designed for application in specific sectors. The researchers have developed the first battery using sodium ions in the usual “18650” format, an industry standard. The main advantage of the prototype is that it relies on sodium, an element far more abundant and less costly than lithium. The batteries have displayed performance levels comparable to their lithium counterparts, and this new technology is already attracting industrial interest. It could be used to store renewable energies in the future, say researchers.
