Printed solar manufacturer lands $2.15 million grant
Kardinia Energy has received a federal grant worth $2.15 million to help scale production of its Newcastle-based printed solar technology.
New single-diode model tackles recombination losses in solar cells
UNSW researchers have developed an intrinsic-adjusted single-diode model that explicitly accounts for radiative and Auger recombination, improving I–V curve accuracy and reducing root mean square error by up to a factor of three. The model is claimed to better predict performance near open-circuit voltage and maximum power point.
New method offers low-cost solution for improving PV system performance
An Australian research team has developed a five-step, rule-based method that detects and classifies underperformance in PV systems using only AC-side inverter data. Validated across more than 1,000 systems, the approach offers a low-cost, low-intervention solution for improving reliability, fault response, and PV system performance.
The effects of solar module elevation on ground-mounted solar
Scientists in Hungary found that ground-mounted solar modules at an intermediate elevation of 1.1 metres achieve the highest efficiency and power output due to improved airflow and reduced cell temperature.
Longi builds 27.25%-efficient back-contact solar cells with high-resistivity wafers
High-resistivity silicon wafers offer superior efficiency potential but are highly sensitive to edge recombination and mechanical damage, limiting their commercial use compared to more robust standard wafers. Researchers from Longi and Sun Yat-sen University demonstrated that integrating in-situ edge passivation unlocks this potential, significantly boosting back-contact solar cell fill factor and efficiency.
IEC-based technical specifications needed for second-life PV module market
The latest report from the International Energy Agency’s Photovoltaic Power Systems Programme says second-life PV modules have the potential to reduce waste and extend the value of solar assets, but their market today remains underdeveloped and requires advances in technical qualifications, scalable reuse infrastructure and supportive policy frameworks.
Chemitek offers solution for drone-based cleaning of agrivoltaics
The Portuguese company said its new Drone AgroPV Cleaning Agent is scheduled for release in June. It has a safe formulation for crops and soil.
NSW claims mine approval boosts clean energy supply chain credentials
The New South Wales government has approved a new copper mine it says will support the state’s renewable energy transition and reinforce its place in global clean energy technology supply chains.
NREL researchers quantify UV-induced degradation levels in TOPCon solar cells
Researchers at NREL found that UV exposure can cause significant, partly non-recoverable degradation in TOPCon solar cells, with strong cell-to-cell and intra-cell variability linked to passivation and processing inconsistencies. While some UV-related losses recover quickly under light and are unlikely to affect field performance, the findings highlight gaps in current qualification tests and the need for improved UV aging standards.
UNSW researchers identify new damp heat-induced failure mechanism in TOPCon solar modules
UNSW researchers identified a new damp-heat degradation mechanism in TOPCon modules with laser-fired contacts, driven primarily by rear-side recombination and open-circuit voltage loss rather than series-resistance increase. The study highlights that magnesium in white EVA encapsulants accelerates degradation, guiding improved encapsulant and backsheet selection for more reliable modules in humid environments.
