With Russia intent on destroying Ukraine’s energy infrastructure, a network of NGOs is taking up the challenge to donate small and mobile energy supply solutions. Astrid Schneider, a member of clean energy nonprofit Eurosolar, shared the story of the small solar kits that are making a big difference, in this month’s edition of pv magazine.

Longi said it has achieved a 26.56% efficiency rating for a gallium-doped, p-type heterojunction (HJT) solar cell and a 26.09% efficiency rating for an indium-free HJT cell, both based on M6 wafers. Germany’s Institute for Solar Energy Research in Hamelin (ISFH) has confirmed the results.

Masdar said it has started operating the 5 MW Ile de Romainville PV project in the Seychelles. The installation is backed by 3.3 MWh of storage capacity.

A recently published report from the IEA-PVPS on building integrated photovoltaics (BIPV) digitalization found many BIPV professionals are unsure of a suitable method for estimating shading in BIPV projects.

The Flemish government will halve the solar panels premium from a maximum of €1,500 ($1,594) in 2022 to €750 from Jan. 1, 2023. It will also end the home battery premium earlier than initially announced, from April 2023. The premium for heat pump boilers, on the other hand, will be retroactively doubled.

Mitsubishi Power Americas will supply batteries for the development of three battery energy storage systems in the southeast US. The three hybrid projects are being developed by Origis Energy as part of 1.5 GW of operational and contracted assets in the region.

Researchers from the United Kingdom, the United States and Australia have reportedly developed a perovskite solar cell with comparable stability and durability to commercial silicon PV cells. They used a high-temperature processing method with dimethylammonium chloride to control the intermediate phases of perovskite crystallization.

Researchers from the Swiss Federal Laboratories for Materials Science and Technology (Empa) have developed a new low-temperature production process for bifacial thin-film solar cells based on copper indium gallium diselenide (CIGS). It resulted in record yields of 19.8% for front lighting and 10.9% for rear lighting.

US-based Emporia Energy has developed a home battery system with an inverter and transformer. The lithium iron phosphate (LFP) battery has a storage capacity of 8.2 kWh, and up to six modules can be combined for up to 49 kWh of energy storage. The inverters come in 7.6 kW or 9.6 kW versions.

China’s National Energy Administration (NEA) said the country installed just under 7.5 GW of new PV in November, bringing cumulative additions in 2022 to 65.7 GW, far short of the estimated 85 GW or more.
