Technology and R&D

A German consortium is building a light commercial truck prototype powered by 10 PV modules featuring Meyer Burger’s heterojunction cells. Initial estimates suggest that the panels could cover more than 25% of a vehicle’s total annual driving distance, and researcher Robby Peibst told pv magazine that the vehicle-integrated photovoltaic market could hit 5 GW by 2030.

Indian scientists tested four kinds of phase change materials (PCMs) for solar module cooling in building-integrated photovoltaics. The PCMs were encapsulated with the PV system and the building envelopes and were also found to be beneficial to the thermal comfort inside the buildings.

Australian public transport operator Transdev will use a “green mobility megawall” comprising 250 solar modules and 10 Tesla Powerwall units to charge two new electric buses in Brisbane.

A homegrown technology developed by the University of Newcastle and Southern Green Gas has seen the development of a novel green hydrogen fuel and carbon-neutral green methane. The fuel was demonstrated in Hyundai’s Nexo hydrogen fuel cell SUV in Sydney.

The New York Power Authority will deploy a battery to provide peak shaving capability. It aims to validate the system’s performance reliability to help determine O&M and life-cycle costs.

Scientists in Russia introduce a promising new material for battery energy storage, the product of more than three years of research. Incorporating a nickel-salen polymer into the cathode, the group demonstrated a battery that can charge and discharge ten times faster than today’s lithium-ion batteries. And though the battery still lags in terms of overall capacity, the group is confident that its discovery will lead to big improvements for lithium batteries.

Many industry sectors across the world are currently being hit by a semiconductor chip shortage as major manufacturers are unable to meet demand. According to Cormac Gilligan, an associate director at IHS Markit, solar and energy storage manufacturers are being less affected. In general, the solar and energy storage industries have learned lessons from being impacted by semiconductor components, for example, transistors, capacitors and resistors in prior years, Gilligan told pv magazine.

A record number of defaults last year has spooked some lenders, according to Solargiga, but the solar manufacturer has announced ambitious plans to ramp production capacity this year and next.

Fraunhofer ISE scientists have identified the best metallization pastes to help reduce contact resistivity and contact recombination in p-type TOPCon solar cells. They applied a silicon nitride layer through plasma-enhanced chemical vapor deposition onto both sides of a cell.

Victorian-based property developer Beulah has announced its soon-to-be-completed Paragon tower, in the heart of Melbourne, will be home to the nation’s largest and most efficient vertical solar PV system.
