EVA-induced degradation has significant impact on power losses in TOPCon solar modules

New research from UNSW shows EVA-encapsulated TOPCon solar modules under damp-heat testing can suffer significant power losses and fill factor drops. The study describes metallisation degradation mechanisms driven by EVA-generated contaminants and demonstrates the effectiveness of metallisation adjustments in reducing EVA-induced degradation rates

Longi achieves 34.85% efficiency for two-terminal tandem perovskite solar cell

The result was confirmed by the United States Department of Energy’s National Renewable Energy Laboratory (NREL).

Fronius launches hybrid inverters for residential, commercial applications

The Austrian manufacturer said its new hybrid inverters can increase the usable output of the PV system to up to 150%. They are available in six version with rated AC power ranging from 15 kW to 33.3 kW.

Global solar module shipments hit 703 GW in 2024

The new edition of the International Technology Roadmap for Photovoltaic, published this week, reports that average PV module prices last year dropped by 33% compared to the end of 2023.

Korean researchers achieve world record efficiency of 23.64% for flexible perovskite-CIGS tandem solar cell

Scientists at the Korea Institute of Energy Research claim to have achieved the highest efficiency ever reported for a perovskite-CIGS tandem solar cell with flexible, lightweight architecture. The device was also found to achieve “excellent” durability.

BYD launches its first integrated home storage system

The Chinese manufacturer said its Battery-Box HVE is now being sold with either a single-phase hybrid inverter or a three-phase device. The system is available in two versions with capacities of 4.29 kWh and 6.45 kWh.

Research shows degradation mechanisms in rear side of TOPCon solar cells

Researchers from UNSW and Longi have found that the silicon nitride layers used in TOPCon cell rear-side are particularly prone to chemical degradation from sodium contaminants. This can lead to significant open-circuit voltage losses and reduce cell efficiency.

BloombergNEF expects up to 700 GW of new solar in 2025

BloombergNEF says global solar installations could reach 700 GW in 2025, with additions rising to 753 GW in 2026 and 780 GW in 2027.

Murdoch Uni explores unmanned ground vehicles for solar plant monitoring

Researchers in Western Australia have reviewed 36 mobile inspection robots for ground-mounted PV plants and have identified six commercial ground robots that are systematically used for this task. Their work presents the robots according to different types of locomotion, navigation technologies, communication technologies, and market status.

UNSW study shows heterojunction solar cell sensitivity to soldering flux

University of New South Wales researchers are part of an international team that has assessed the impact of soldering flux on heterojunction solar cells and has found that the composition of this component is key to prevent major cracks and significant peeling.
