This Small Business Innovation Research (SBIR) Phase II project will develop novel space-stable and scalable packaging technologies for ultrathin silicon solar cells.
The PCE of the hybrid BC silicon solar cell with an area of 158.75 × 158.75 mm 2 was tested with a mask aperture area of 209.8 cm 2. Finally, the PCE of the 1 cm 2 ST-PSCs was added to the PCE of the hybrid BC silicon solar cell under light filtering to obtain the PCE of the 4T tandem solar cell.
H.W. performed the measurement and analysis of residual strain. K.L. and X.Y. prepared the large-area perovskite filter sample. J.Z., J.H., and Q.Z. completed the preparation and certification of hybrid-BC silicon solar cells. All authors discussed the results and contributed to the revisions of the manuscript.
The hybrid BC silicon solar cell was obtained from Gold Stone (Fujian) Energy Company Limited and fabricated through the following process. First, the N-type monocrystalline silicon wafer (a) was double-sided polished in 20% KOH solution to remove the damage layer, and then cleaned using the RCA standard process.
The hybrid-BC silicon solar cell working under the transmitted light was tested and reached a third-party certified PCE of 12.71% (Supplementary Figs. 32 and 33). Therefore, we achieved four-terminal perovskite/silicon tandem solar cells with a record-certified efficiency of 33.10% (Fig. 4g and Table 1).
One of Hungary's largest battery energy storage facilities has been completed in Szolnok. Built by Forest-Vill on behalf of MAVIR, the system officially began operations on June 26. 5 billion investment aims to support the grid integration of solar power plants. Greenvolt Power has officially inaugurated Hungary's largest Battery Energy Storage System (BESS) currently in operation, marking a major milestone in the company's expansion across Central and Eastern Europe and reinforcing its commitment to advancing large-scale energy storage solutions. It also targets reducing Hungary's dependency on fossil fuel imports, notably natural gas from Russia, while accelerating the energy transition in line with the REPowerEU Plan and the Green Deal. The Hungarian government has earmarked HUF 62 billion ($169 million) for grid-scale energy storage projects in a bid to facilitate further deployment of renewable energy sources. Hungarian authorities launched the tender for grid-scale batteries on January 15 and received offers until February 5.

Polycrystalline silicon, or multicrystalline silicon, also called polysilicon, poly-Si, or mc-Si, is a high purity, polycrystalline form of silicon, used as a raw material by the solar photovoltaic and electronics industry. Polysilicon is produced from metallurgical grade silicon by a chemical purification process, called the Siemens process. This process involves distillation of volatile silicon compounds, and th. Comparison to monocrystalline siliconIn single-crystal silicon, also known as, the crystalline framework is homogeneous, which. At the component level, polysilicon has long been used as the conducting gate material in and processing technologies. For these technologies, it is deposited using low-pressure chemical-vapour dep. Polysilicon deposition, or the process of depositing a layer of polycrystalline silicon on a semiconductor wafer, is achieved by the of (SiH4) at high temperatures of 580 to 650 °C. This process.

Latin American power utility Celsia SA said on Monday that Colombia's first solar energy storage, using a lithium iron phosphate (LFP) battery, will start operations at a 9.
AES Andes has announced it will discontinue its INNA green hydrogen project to focus on renewable energy and energy storage development in Chile. has canceled its 800 MW Paposo Pumping Central project in Chile after difficulty with the environmental review process, the Chilean utility announced. Colbún submitted its environmental impact assessment (EIA) last June, but the Antofagasta Environmental Assessment Service (SEA). Chile utility Colbun has faced a setback with its 800MW pumped hydro energy storage (PHES) project after its environmental impact assessment (EIA) process was terminated early, having been deemed to have provided too little information. The firm proposed the Paposo Pumped Power Station earlier this. During a keynote speech at the 4th Latin America Energy Storage Summit, Ana Lía Rojas, Executive Director of the Chilean Association of Renewable Energies and Energy Storage (ACERA), revealed that as of August 2025, the curtailed energy from solar and wind sources in Chile had reached 3.
