AI now can now predict solar cell efficiency from wafer quality
Korea University researchers have developed a machine-learning framework that predicts solar cell efficiency from wafer quality, enabling early wafer screening and optimized production paths. Using over 100,000 industrial data points, the approach combines predictive modeling, process optimization, and explainable AI to support photovoltaic manufacturing.
Global utility-scale battery capacity rises 12-fold in 2020-24 period
The global capacity of utility-scale batteries increased more than 12-fold between 2020 and 2024 to 124 GW, while average battery costs fell 58% over the period, according to the Electricity 2026 report from the International Energy Agency (IEA).
Bert Thin Films launches copper paste for backside solar cell metallization
The U.S. startup has introduced a screen-printable copper paste for backside solar cell metallization that can be fired in air and co-fired with standard silver frontside pastes using conventional manufacturing processes. Tested on TOPCon cells, the paste contributed to achieve a 25% efficiency and passed 2,000-hour damp heat testing.
De-risking redox flow batteries for grid-scale storage
Following their review of redox flow battery research, Norway-based scientists told pv magazine that despite its high upfront capital costs and lower energy density relative to metal-ion, the technology can offer safety, reliability, and scalability advantages for standalone, large-scale applications.
ACME Solar signs 190 MW hybrid PPA with SECI in India
ACME Solar Holdings has signed 25-year 190 MW wind-solar hybrid power purchase agreement (PPA) with Solar Energy Corp. of India (SECI) requiring 50% annual capacity utilization factor and 80% daily peak supply obligation.
Pay-as-you-go solar often underutilized in Sub-Saharan Africa
A study of 1,000 sub-Saharan African households using off-grid PAYG solar systems found that 77% reduce their electricity use after the first year, leading to underused, often oversized systems. This persistent decline is driven by behavioural changes as well as economic constraints and highlights the need for solar designs and pricing that better match actual household energy needs.
Luxembourg launches new tender for C&I solar
Luxembourg’s Ministry of the Economy has launched a €3 million ($3.54 million) tender to support commercial and industrial (C&I) solar projects between 30 kW and 200 kW, with applications open until April 17.
Burundi switches on solar at five health facilities
A United Nations Development Programme (UNDP)-led initiative has installed hybrid solar-plus-storage systems at five health facilities in Burundi. A second phase of the scheme, due for completion this year, will power an additional nine district hospitals.
Mexico could become data center hub, but clean power lags behind
Mexico is attracting US data centers seeking faster power connections, but these facilities will initially rely on firm gas generation from the Comisión Federal de Electricidad (CFE), with renewables as a potential future option, Mexican energy expert Santiago Barcón told pv magazine.
Centrotherm launches new high-volume TOPCon PECVD tool
The Germany-based PV thermal process equipment and technology provider has launched c.Plasma Q Max to process up to 10,000 wafers per hour in high-volume TOPCon solar cell manufacturing lines.
