Flexible all-perovskite tandem solar cell with 23.8% efficiency, improved voltage
A Chinese-Swiss research group claims to have overcome two major challenges for the development of flexible all-perovskite tandem solar cells – voltage losses and the deposition process for the cell’s functional layers. They built a device with a high open-circuit voltage of 2.1 V.
GoodWe unveils high-voltage hybrid inverter for C&I applications
GoodWe’s new hybrid inverters have efficiency ratings of 98.0% and European efficiency ratings of 97.5 %. They are available in five versions, with power outputs ranging from 15 kW to 30 kW.
TOPCon solar cell achieves 24.2% efficiency via new plasma-assisted atomic layer deposition tech
A team of international researchers has simplified the deposition of thin film layers in the commercial production of TOPCon solar cells. Via a tube-type industrial plasma-assisted atomic layer deposition (PEALD) technique, they were able to achieve a power conversion efficiency of 22.8% in a 60-cell, 613 W TOPCon module.

IEA-PVPS expects polysilicon prices to stabilize by end of 2023
The International Energy Agency Photovoltaic Power Systems Programme (IEA-PVPS) recently published a report on trends in PV applications for the 2021-22 period. Prices for polysilicon, wafers, cells and modules rose, while production capacity expanded in China and beyond.
The Hydrogen Stream: UK consortium plans 10 MW offshore wind-hydrogen facility
A group of UK companies has started working on a 10 MW wind-to-hydrogen project, American Airlines has announced a new investment in hydrogen distribution, and ACWA Power has teamed up with South Korea’s Kepco to develop green hydrogen/ ammonia projects in the Middle East.
‘Footstep tech’ for solar module cleaning
Scientists in South Korea have used a triboelectric generator and an electrodynamic dust shield to develop a panel-cleaning system that can be activated by footsteps. They said the system can remove more than 70% of accumulated dust with the pressure of just 12 footsteps.
