A study analyzing urban bifacial PV systems in high-latitude areas found they can generate 9–13% more electricity than monofacial panels under snow conditions, particularly in winter, while also achieving a lower levelized cost of electricity. The research developed a techno-economic optimization model considering snow effects, panel orientation, interrow spacing, and operation modes, highlighting sensitivity to market conditions and discount rates.

The research group led by Professor Martin Green has not published yet Version 67 of the solar cell efficiency tables, due to production delays. Green, however, has accepted to comment on some of the results to be added in the upcoming edition.

Accelerated testing by French certification body Certisolis finds wide performance divergence and design vulnerabilities in tunnel oxide passivated contact (TOPCon) solar modules that current international standards do not capture.

Researchers at the Chinese Academy of Sciences developed a thermoacoustic Stirling heat pump prototype that offers high thermal performance, a peak coefficient of performance of 1.68, and potential applications in high-temperature industrial processes, enabling zero-carbon heating for sectors like petrochemicals and metallurgy.

UNSW and Jolywood studied the thermal stability of laser-assisted fired TOPCon solar cells during module fabrication and high-temperature stress, identifying hydrogen-related defect dynamics as the key factor behind degradation and recovery. They found lamination causes temporary efficiency losses that self-recover under light exposure, while optimized LAF can restore degraded contacts, providing practical guidance for reliable module manufacturing and testing.

Market trends suggest battery energy storage systems (BESS) will likely operate 1.5 cycles per day, bringing the effective storage cost down to just INR 2.8/kWh (0.031/kWh), the Ministry said on Monday.

The battery is rated at a nominal 48 V and 314 Ah, with an ingress protection level of IP20.

Germany has connected the world’s first supercapacitor-based STATCOM to the grid, with Siemens Energy and transmission system operator TenneT positioning it as a blueprint to replace fossil-fuel generators in providing instantaneous reserve and reactive power.

The Chinese energy and oil company said the cell can be used as a top device in perovksite-silicon tandem configurations. The result was confirmed by the Shanghai Institute of Microsystem and Information Technology (SIMIT).

A group of scientists has simulated fixed vertical, interspace and overhead single-axis as well as overhead dual-axis agrivoltaic systems for 30 years and has found interspace single-axis system emerged as the most environmentally favorable configuration in Europe.
