Researchers led by Fraunhofer ISE have demonstrated zinc-doped tin oxide (ZTO) as a promising indium-free alternative to indium tin oxide (ITO) for recombination layers in fully textured perovskite-silicon tandem solar cells. ZTO offers comparable device efficiencies of 27-28% under current-matching conditions, providing a scalable, indium-free pathway for high-performance tandem photovoltaics without efficiency loss. The study compared ZTO, aluminum-doped zinc oxide (AZO), and ITO transparent conductive oxides, with ZTO showing superior compatibility with hybrid-processed perovskite top cells on TOPCon-based perovskite-silicon tandem solar cells. The research emphasizes the importance of processing parameters such as sputter parameters and annealing in tuning the structural and electrical properties of the transparent conductive oxides.

Inside the financing of Egypt’s largest solar‐plus‐storage project
Norwegian developer Scatec ASA has commissioned the first phase of the 1.1 GW Obelisk solar and battery energy storage system project in Egypt, financed with multilateral development bank debt and equity from a Norwegian climate fund and a French energy company. The project, fully contracted with a power purchase agreement (PPA) to eliminate merchant exposure, includes 561 MW of solar and a 100 MW/200 MWh battery storage system in the first phase, with an additional 564 MW of solar to be added in the second phase. With the aim of accelerating the transition to renewable energy in emerging markets, the project is backed by a sovereign guarantee, highlighting a significant step towards climate solutions in the energy sector.

The U.S. Is Manufacturing a Ton of Grid Batteries
The United States has made significant progress in producing its own energy storage systems, with batteries accounting for 28 percent of new power plant capacity this year. President Joe Biden's Inflation Reduction Act has incentivized domestic battery production, leading to self-sufficiency in grid battery enclosures and cells. By the end of 2025, the US is projected to have the capacity to produce 145 gigawatt-hours of finished grid storage systems annually. The industry now faces the challenge of potentially exporting surplus batteries to maintain manufacturing potential. LG Energy Solution Vertech is leading the rapid growth in grid-battery manufacturing, with plans to increase cell production capacity to 50 gigawatt-hours across North America this year. The Department of Energy is investing $500 million in funding to strengthen battery supply chains domestically, emphasizing the importance of a resilient and responsive supply chain for delivering power quickly. U.S. manufacturing can improve delivery certainty and shorten project timelines, with industrial reshoring seen as a way to protect against geopolitical uncertainties and disruptions caused by the White House. A local supply chain helps protect against U.S.-led disruptions in the global trade.

Largest US renewable project begins generating electricity
The largest renewable energy project in the US, SunZia Wind, has begun generating electricity with 916 turbines in New Mexico. The 3.5-gigawatt wind development will deliver power to California over a 550-mile transmission line, crucial for meeting the state's clean energy goals. Despite facing delays and opposition, the project is seen as a significant step towards reducing carbon emissions and meeting energy demands. SunZia's integration into the grid is helping to retire polluting natural gas plants in environmental justice communities and increase renewable energy generation, surpassing other major wind projects in the US in terms of size and operational progress.

Fossil fuels face higher taxes than electricity under EU bill
The European Commission is set to unveil a bill that will tax electricity at a lower rate than fossil fuels as part of a strategy to shift towards more renewable and nuclear energy sources. This initiative comes in response to the energy crisis following Russia's invasion of Ukraine and aims to make energy more affordable and reliable. The EU executive is preparing measures to mitigate the economic impact of the Iran war, which has disrupted oil and gas supplies from the Gulf region. The goal is to reduce dependence on fossil fuels and increase electricity generation from renewables and nuclear power.

Huge wind component of massive hybrid renewables project joins queue for federal green tick
A 2 gigawatt hybrid wind, solar, and battery storage project in Western Australia's Mid West region, the Tathra wind farm, is undergoing federal environmental assessment after securing state approvals. Developer SynergyRED aims to combine up to 1,000 MW of wind, 500 MW of solar, and 500 MW of battery energy storage to maintain affordable and reliable electricity supply. Efforts are being made to minimize impacts on fauna habitat in the mainly agricultural project area. Additionally, Synergy is expanding its battery capacity with the Collie battery, increasing total big battery capacity to over 800 MW and nearly 3,200 MWh, marking a significant step towards clean energy solutions.

Maryland regulators weigh investor-owned utilities’ flexible load proposals
Maryland utilities are working to aggregate up to 440 MW of flexible load resources, such as residential thermostats, distributed batteries, and electric vehicles, to support state-mandated virtual power plants and load management programs. The Distributed Renewable Integration and Vehicle Electrification Act requires utilities to develop vehicle-to-grid charging and VPP plans. Utilities like BGE, Pepco, Delmarva, and Potomac Edison are implementing time-of-use tariff proposals and pilot programs to increase customer participation in grid flexibility initiatives. The Maryland Public Service Commission has accepted modified time-of-use tariffs but rejected pilot proposals, ordering utilities to refile them for further clarity. The goal is to integrate customer-owned devices into utility operations while providing incentives and maintaining customer control, ensuring the success of demand-side management programs and distributed energy resource integration efforts in reducing peak load in a locationally relevant manner.
