A U.S.-based collaboration between the National Renewable Energy Laboratory (NREL) and CubicPV has yielded a perovskite minimodule with certified efficiency of 24.0%. The two noted that it is the first time a U.S. effort has set a record in the perovskite mini module category.

German software company PVRadar Labs has released a Python programming package for solar asset owners and engineers that want to build site-specific models.

A research team led by the Dalian Institute of Chemical Physics in China have used tetramethylammonium chloride in the fabrication of perovskite solar cells and modules, demonstrating that it improved both stability and efficiency results. The group’s 10 cm × 8 cm modules achieved certified 21.60% power conversion efficiency. The novel interfacial modification enabled the use of scalable blade coating to deposit both transport layers and the perovskite layer.

The Netherlands-based solar façade panel and mounting system provider has added a new terracotta rooftop module to its product range. It also announced it is expanding it sales network and boosting its manufacturing capacity after raising €5.5 million in financing.

Researchers in Europe are investigating semi-transparent solar windows, applying microfabrication technniques to both CIGS and perovskite devices, to overcome the view-impeding properties of earlier solar window concepts.

SolarPower Europe has underscored the role of domestic mounting system manufacturers in driving PV deployment across Europe, while calling for the adoption of international customs codes, stricter quality standards, and the inclusion of fixed-tilt racking systems in national resilience technology lists under the EU Net-Zero Industry Act (NZIA).

A team of UK researchers is working on lightweight cadmium telluride (CdTe) solar devices for space arrays. The aim is to develop 20%-efficient ultra-thin devices to provide lightweight, compact, lower cost solar power for satellites and space-based manufacturing applications.

Researchers in Italy are tackling two metal halide perovskite solar PV challenges, reduce the use of lead and extend stability of the power conversion efficiency, in a novel combination of micro-concentrators and picosecond laser processing.

A Swiss research team has developed a novel single-step annealing process for tunnel oxide passivating contact (TOPCon) solar cells. Demonstrating the approach, the scientists built a proof-of-concept TOPCon device with a 21% efficiency.

Sofab Inks, a spinoff of University of Louisville in the United States, says its transport layer materials enable perovskite solar cells with greater stability, efficiency, and scalability compared to incumbent materials.
