Researchers at Tohoku University in Japan have developed a prototype calcium battery with a long cycle life of more than 500 charge-discharge cycles. The battery was developed using a hydride-based electrolyte and copper sulfide nanoparticle/carbon composite cathode.

The African Development Bank (AfDB) has launched an expression of interest for a consulting study on solar manufacturing in the Desert to Power Sahel countries. Interested parties have until June 7 to submit their bids.

An international research team has crafted an innovative solar cell design. By employing a top absorber consisting of methylammonium lead iodide (MAPbI3), a lead-halide perovskite, and a bottom absorber composed of FA0.5MA0.5Pb0.5Sn0.5I3, a perovskite material, the cell maximizes light absorption across a broad spectrum.

China-based researchers have developed a model for photovoltaic pavement, achieving a potential electrical output of 0.68 kWh/m2 and an efficiency of 14.71%. Through simulations across 255 Chinese cities, they have determined that electricity potential ranges from 0.70 kWh/W to 1.83 kWh/W.

The European Solar Test Installation (ESTI) has confirmed the results of King Abdullah University of Science and Technology’s (KAUST) new perovskite/silicon tandem solar cell. The 1 cm2 device also achieved an open-circuit voltage of 1.974 V, a short-circuit current density of 20.99 mA/cm2, and a fill factor of 81.3%.

A new study has evaluated the development of agrivoltaics in India, analyzing the challenges and opportunities involved in scaling up such projects, and exploring their potential for commercialization.

Norwegian startup Over Easy has validated the wind resistance of its vertical PV system for rooftops by using computational fluid dynamics (CFD) simulations. Wind tunnel tests conducted by I.F.I. Institut für Industrieaerodynamik GmbH confirm that the system can function without ballast or fastening to the rooftop.

An international research team in China has used Czochralski n-type c-Si wafers from China-based Sichuan Yongxiang to build textured wafers with a thickness ranging from 65 μm to 55 μm. They have used the wafers in heterojunction solar cells ton hit efficiencies close to those of devices cells based on conventional wafers.

A Japanese consortium is now testing a 100 kW fuel cell system in Tokyo. The system uses green hydrogen and waste plastic hydrogen to provide heat to an industrial building. The demonstration aims to establish an urban hydrogen energy utilization model that combines global and local hydrogen sources.

Researchers have achieved an efficiency boost of 15.44% to 17.04% in all-inorganic perovskite solar cells by incorporating a conductive fullerene-derivative interlayer between the perovskite and electron transport layers. They claim that this enhancement also improves thermal stability.
