Tongwei achieves 31.4% efficiency for perovskite-silicon tandem solar cell
Chinese researchers, led by a research team from PV Technology Centre of Tongwei Co., Ltd, used a sequential annealing process in the fabrication of tandem solar cells, featuring a wide bandgap perovskite top cell on a fully-textured commercial crystalline silicon heterojunction bottom cell. The resulting device had a certified power conversion efficiency of 31.4%, outperforming a 29.43%-efficient control cell.
Macquarie-backed Blueleaf progresses 3 GW solar and storage plan for Malaysia
Macquarie-owned renewables platform Blueleaf Energy will explore the potential development of 3 GW of solar PV and battery energy storage projects in Malaysia after striking a deal with a local advisory firm.
Seasonally optimised PV panel tilt can boost yield by up to 9%: study
In the Indian state of Rajasthan, a new study investigates the seasonal optimisation of PV module tilt angles to optimise the energy efficiency, revealing that dynamic tilt adjustments can significantly boost annual solar yield across diverse climatic zones.
JinkoSolar presents 475 W TOPCon dual-glass solar panel with 23.77% efficiency
The Chinese manufacturer said its new IEC 61215-certified rooftop PV module relies on a 30 mm aluminum frame and dual-glass construction that reportedly help it withstand extreme snow loads and wind pressure.
MaxVolt launches smart inverter with inbuilt lithium battery
The Indian battery manufacturer has launched a wall-mountable, high-efficiency inverter with inbuilt lithium battery for residential and commercial solar applications.
Indonesia announces 100 GW solar, storage minigrid plan
The new initiative features plans for 1 MW solar minigrids tied with 4 MWh of accompanying battery energy storage, to be deployed across 80,000 villages, alongside 20 GW of centralised solar power plants.
Aiko offers 500 W all-back contact solar modules for C&I applications
The Chinese manufacturer has upgraded its Infinite ABC solar module series with four new product versions. It claims the new modules are the world’s first 500 W panels measuring less than 2 m2.
Philippines completes first MW-scale floating solar array
The Philippines has completed its first megawatt-scale floating solar array, a 4.99 MW installation on the Malubog reservoir, with plans to expand to 50 MW to power a copper mine. In Mindanao, work has begun on a 99 MW solar plant backed by about $120 million in green financing from HSBC.
Vertical bifacial photovoltaic balustrade for building edges
Conceived by scientists in Hong Kong, the solar balustrade integrates bifacial PV panels and is considered an ideal solution for “cool roofs.” Roof albedo and module orientation are critical drivers of system performance.
Solar module fault diagnosis uses convolutional neural network
Researchers in China have created a dataset of various PV faults and normalised it to accommodate different array sizes and typologies. After testing the new approach in combination with the 1D-CNN machine learning technique under different conditions, they found an accuracy of more than 99%.
