FuturaSun Announces New Breakthrough in Perovskite-Silicon Solar Technology
The solar industry is buzzing with a significant announcement that could reshape the future of renewable energy. On December 19, 2025, Italian solar manufacturer FuturaSun, in partnership with Eni’s corporate venture builder Eniverse, officially launched SunXT. This new joint venture is set to accelerate the development and industrialization of a groundbreaking technology: perovskite-silicon tandem photovoltaic panels.
For homeowners and tenants in Germany, where maximizing energy production from limited roof or balcony space is a key priority, this development signals a promising leap forward in solar efficiency and power generation.
The SunXT Venture: Integrating Perovskite-Silicon Solar Technology Expertise
SunXT represents a strategic collaboration designed to bring next-generation solar technology from the laboratory to the market. The venture, owned 56.1% by FuturaSun and 43.9% by Eniverse, builds upon the foundation of Solertix, a deep-tech startup from FuturaSun that specialized in tandem photovoltaics. This new entity combines Solertix’s patents and expertise with Eni’s advanced research into perovskite materials.
Laura D’Angelo, Venture Strategy Director at Eniverse, highlighted the importance of this technology in Eni’s decarbonization strategy. FuturaSun echoed this sentiment, emphasizing its commitment to commercializing research that began over a decade ago, with the goal of boosting panel performance and reducing the overall cost of solar energy. This move is part of a wider global push, with various organizations investing heavily in impressive Perovskite solar panel R&D to unlock new levels of performance.
The Technology: Enhanced Power with Perovskite-Silicon Solar Technology
At the heart of the SunXT venture is the tandem solar cell. Unlike conventional panels that use only silicon, tandem cells stack a perovskite layer on top of a traditional silicon layer. This allows the panel to capture a wider spectrum of sunlight and convert it into electricity more efficiently.
SunXT’s innovative approach features a four-terminal bifacial design. This architecture pairs a perovskite module with a traditional silicon module, enabling it to capture sunlight from both the front and back sides. This not only maximizes light absorption but also enhances efficiency and versatility, making the technology highly competitive against standard silicon panels. Pushing the boundaries of efficiency and stability is the primary goal of Perovskite Solar Cells: A Breakthrough for Efficiency & Stability.
The use of different solar panel raw materials in tandem cells is key to their enhanced performance, moving beyond the theoretical limits of silicon-only technology.
The Path to Market
The journey from concept to commercial product is a carefully planned process. SunXT has outlined a two-phase approach:
1. Pilot Production: The initial stage will focus on establishing a pilot production line to refine the solar panel manufacturing process and ensure consistent quality and performance.
2. Industrial Scale-Up: Following a successful pilot phase, the venture will scale up to industrial-level production, aiming to supply panels for residential, commercial, and large-scale utility projects.
While no commercial products are available yet, this structured plan demonstrates a clear commitment to making this advanced technology accessible.
What This Means for Germany’s “Energiewende” and Perovskite-Silicon Solar Technology
For those participating in Germany’s energy transition, or Energiewende, this announcement is particularly relevant. Higher-efficiency panels mean generating more power from the same surface area—a critical advantage for urban homes with limited roof space or for tenants using “balcony power plants” (Balkonkraftwerke). By producing more electricity, households can further reduce their reliance on the grid, lower their energy bills, and make a greater contribution to Germany’s renewable energy targets.
This European-led innovation also speaks to a broader trend of strengthening the continent’s solar manufacturing capabilities, ensuring a more resilient and independent energy future. Understanding the basics of solar panel manufacturing helps appreciate the significance of bringing such advanced production back to Europe.
The SunXT venture by FuturaSun and Eniverse is more than just a corporate announcement; it’s a significant step toward the next generation of solar power. By combining perovskite and silicon, this technology promises to deliver the efficiency gains needed to accelerate the global transition to clean energy.
