The Japanese electronics manufacturer has launched the NU-JC440 and NU-JC430B panels with efficiencies of 22.53% and 22.02%, respectively. Both products are IEC/EN61215 and IEC/EN61730-certified and rely on M10 wafers.

A U.S. research team has investigated the thermomechanical reliability of metal halide perovskite (MHP) modules and cells in an effort to identify the best strategies to improve their stability under thermomechanical stressors. The scientists discussed, in particular, film stresses, adhesion of charge transport layers, and instability under light and heat.

Scientists in South Africa have modeled a photovoltaic system connected to a thermoelectric cooling device and have found it may produce around 9.2% more electricity than conventional PV system without cooling. The research team claims the proposed system guarantees a minimum cost saving of 10.56%.

India’s solar module exports hit $1.9 billion in fiscal 2023-24, with shipments to the US market accounting for the lion’s share of the total.

A Chinese research group including scientists from module maker Tongwei has designed a perovskite solar cell with remarkable perovskite film quality through the so-called self-disintegrating seed strategy. The device not only achieved one of the highest fill factor values ever recorded for perovskite solar to date, but also showed remarkable stability.

Genex Power has appointed UK-based engineering and design company Arup as owners’ engineer for the first stage of the 2 GW Bulli Creek solar project. The installation is set to become the biggest solar farm on Australia’s main grid.

CEZ Group has developed a new solution for securing solar photovoltaics in areas of unstable subsoil from the central section of conveyor belts previously used in strip coal mines. Several pilots of the steel structure have already been deployed on a reclaimed area near the Bílina Mine in northern Czechia.

Researchers at the University of South Carolina have successfully transitioned their highly-durable lithium-sulfur battery technology from coin to pouch cells and reported competent energy densities.

Researchers in Nigeria have proposed to build inverted perovskite solar cells exclusively with all-inorganic transport materials and a lead-free perovksite absorber. Through a series of simulations, they showed these device may achieve efficiencies over 30% with low production costs.

Swiss consulting firm Pexapark says the total capacity of signed power purchase agreements (PPA) in Europe in April more than doubled the volume it recorded in March. Meanwhile, all tracked PPA prices rose 1.6% month on month.
