Standalone solar-powered refrigerators present a $20 billion opportunity in India for vaccine storage, milk chillers, households, micro enterprises, and cold storage for farm produce, according to a new report by Gogla.

Australian researchers have analyzed different ways to improve the efficiency of PV-powered water electrolysis for hydrogen generation. They include the use of magnetic fields, light energy, ultrasonic fields, and pulsating electric fields. Energy costs remain prohibitive, but molecular movement and the redistribution of molecules in water during electrolysis could open a path to viability.

Batteries based on vanadium or zinc bromide represent the cutting edge of redox flow storage tech, an international research team has claimed. They have identified challenges and opportunities for about a dozen redox flow storage technologies, while providing estimates of their current and projected levelized costs of storage.

Scientists in Spain and Colombia took a closer look at the degradation mechanisms affecting perovskite solar cells, and developed a new, high throughput method to characterize their performance in an outdoor setting. The group evaluated the method through outdoor testing on perovskite modules manufactured in a lab. it expects its findings to offer easier device characterization and better understanding of the degradation mechanisms affecting perovskite solar cells, both important factors in the technology’s development.

Iranian scientists have assessed a new active approach for solar module cooling based on water spraying. Water sprayed from different angles can reduce the operating temperature of PV modules, with limited water consumption. However, the team noted that they have yet to assess the economic viability of the system.

German scientists have designed a manufacturing process to reduce the thickness of the molybdenum diselenide interface layer in kesterite solar cells. They used two different configurations of silicon-oxynitride diffusion-barrier layers.

Western Australia-based solar glass developer ClearVue has commenced installation of its transparent solar PV glazing panels at what will be the world’s first clear solar glass greenhouse.

What happens to a floating PV system located in cold climates during freezing temperatures? How is the plant handled and which kind of risks could be associated with these unfavorable climatic conditions? We have sought to answer these questions with the help of Kane Wang, manager of Sungrow Floating’s system solution department.

The two companies want to test a floating PV array under harsh weather conditions in rough waters for at least a year. The system will be based on a floating solar technology developed by Maritime Moss, a unit of Saipem.

German scientists have fabricated an enhanced amorphous germanium PV cell that confines light in an ultra-thin absorber. It has the potential to combine PV with photosynthesis in new solar applications on bio-reactors, greenhouses, and agricultural land.
