The International Energy Agency (IEA) has published its “World Energy Outlook 2022” report. It expects the energy crisis triggered by Russia’s invasion of Ukraine to accelerate the global energy transition.

Cobalt is key for boosting energy density and battery life, but it comes with caveats: expensive, scarce, and linked to unethical mining practices, wild price fluctuations, and a tenuous supply chain. In recent years, battery manufacturers and automakers have intensified efforts to reduce or eliminate cobalt in lithium-ion cathodes. But sometimes, old habits die hard, as pv magazine’s Marija Maisch explains.

Italian startup Tialpi is developing a process to recycle end-of-life solar panels that promises to recover 100% of a PV module’s weight. The new plant design is currently being tested at the company’s facility in the Italian northern province of Biella.

US-based Nanotech Energy’s graphene battery uses proprietary electrodes with a thermally stable separator, and non-flammable electrolyte that is said to be inexpensive to manufacture. The technology is said to be superior in terms of safety and competitive in terms of cell performance.

Germany’s Paxos is currently testing the solar tile in a testing facility connected to an air heat pump. The panel can provide heat and electricity at the same time, while also improving the heat pump’s coefficient of performance by around 25%.

The consulting firm expects prices to decline gradually through the first semester of 2023, followed by an accelerated decline in the second half of the year, with prices falling from the current CNY 300 ($36.64)/kg to below CNY 150/kg by the end of 2023. Polysilicon production capacity may increase from 500 GW in 2022 to 975 GW next year.

Indian researchers have compiled an extensive review of all existing synchronization techniques for grid-connected PV systems. They divided the methods into open-loop and closed-loop systems and provided what they defined as a basic conceptual framework to develop superior grid-tied systems.

Norway’s SINTEF has designed a heat storage system based on phase change materials (PCM) that can support PV generation and peak shaving. The battery’s container hosts 3 tons of liquid biowax based on vegetable oil and is now beating performance expectations at a pilot facility.

The International Energy Agency Photovoltaic Power Systems Programme (IEA PVPS) estimates that 173.5 GW of new solar capacity was installed in 2021, and that figure might rise to 260 GW in 2022. pv magazine spoke with the co-chair of the European Solar Manufacturing Council to look into the figures.

A team of international researchers has simplified the deposition of thin film layers in the commercial production of TOPCon solar cells. Via a tube-type industrial plasma-assisted atomic layer deposition (PEALD) technique, they were able to achieve a power conversion efficiency of 22.8% in a 60-cell, 613 W TOPCon module.
