Building-integrated PV system integrates PCM on sides
Scientists have designed a new building-integrated PV system that uses 30 mm of phase change material on each side of the wall. The array reportedly achieved superior thermoelectric coupling performance compared to reference BIPV systems without PCM.
New research shows vulnerability of TOPCon solar cells to contact corrosion
Researchers at the University of New South Wales claim to have identified new TOPCon contact degradation mechanisms that are significantly influenced by the combination of ions and aluminum-silver paste compositions. The primary degradation mechanism was a significant increase in series resistance.
Riding China’s green capital tsunami to harness cleaner future for Australia
As the world races to decarbonise, China is leading the way. It committed more than $145 billion (USD 100 billion) in outbound foreign direct investment since 2023 across decarbonisation sectors including solar, wind, batteries, grid, new energy vehicles, hydro and green hydrogen.
Hinen unveils all-in-one home energy storage solution
Chinese manufacturer Hinen has launched an integrated battery energy storage system with power options ranging from 3.6 kW to 25 kW for on- and off-grid residential applications.
Trina Solar presents ‘fully recyclable’ 645 W PV module
Trina Solar claims it has developed the world’s first “fully recyclable” 645 W PV module with 20.7% efficiency. It made the panel with interlayer separation reagents, chemical etching technology, and wet chemical silver extraction tech.
Longi, ANU develop gettering-based process to improve n-type wafer quality
The Chinese module maker and the Australian National University utilised phosphorus diffusion gettering and another defect mitigation strategy to improve the quality of n-type wafers. The proposed process contributed to improve the material quality especially towards the tail-ends.
Envertech launches microinverters for PV systems with up to 60 modules
Envertech says it has developed microinverters for PV systems supporting up to 60 modules, allowing up to four modules per unit with separate maximum power point tracking.
New deep learning tech uses electroluminescence images to identify defective PV cells
The novel method uses the YOLOv8 framework, integrating an attention mechanism and a transformer model. It was tested on a dataset of 4,500 electroluminescence images against several other models and its results were up to 17.2% more accurate.
China connects first large-scale flywheel storage project to grid
The 30 MW plant is the first utility-scale, grid-connected flywheel energy storage project in China and the largest one in the world.
Lightweight ventilated BIPV system for low-load rooftop applications
Scientists in China have designed a ventilated building-integrated photovoltaic system that relies on flexible solar modules with a weight of 6 kg/m2. The system also uses an airflow channel under the PV panels to reduce their operating temperature and increase their power yield.
