Researchers at the Australian National University are part of the international team that has built an all-perovskite tandem solar cell based on a wide-bandgap top perovskite cell with a 20.5% efficiency. The 1 cm2 scale tandem device achieved the highest efficiency yet reported for all-perovskite solar cells of this size.

The latest supply chain map from Sinovoltaics tracks growth across Southeast Asia, with module capacity reaching 78.8 GW, and 58 production projects tracked.

The latest irradiance sensor solution from Japan-based EKO Instruments provides continuous measurements in the field. Well-suited for bifacial PV systems, it supports the measurement of global horizontal irradiance, diffuse horizontal irradiance and direct normal irradiance, even in reflective and cloudy conditions.

The Chinese module maker and the Australian National University utilised phosphorus diffusion gettering and another defect mitigation strategy to improve the quality of n-type wafers. The proposed process contributed to improve the material quality especially towards the tail-ends.

Researchers at Queensland’s James Cook University have developed a process to synthesise graphene from tangerine peel oil, which they then used to recover silver from waste PV material.

The third edition of the Sinovoltaics financial stability report ranking lists India-based Abhishek Corp, Insolartion Energy, Waaree Renewable Technologies, and Solex Energy, all based in India, followed by United States-headquartered First Solar as the top five. Six additional manufacturers entered the global ranking.

United Kingdom–based technology company Sunswap has launched Endurance, an electric transport refrigeration system with integrated battery and solar PV. It is built to compete with diesel-powered systems.

A review of indoor PV cell technologies by an international research team delves into recent progress, characterisation, and design strategies used to develop highly efficient cells. The study presents 250 commercial and laboratory devices, as well as applications and performance reporting.

The IEA Photovoltaic Power Systems Programme’s (IEA-PVPS) latest report on solar panel recycling offers a comprehensive review of all existing technologies in this market segment, from pure mechanical recycling to innovative techniques such as light pulse treatment, water-jet cleaning, pyrolysis, and chemical treatments.

Taiwanese manufacturer Winaico said its newest bifacial, n-type, glass-glass TOPCon compact modules are available in a 435 W aluminum-framed version, and a 430 W full-black version. The module efficiency is up to 22.30%.
