Researchers have developed semi-transparent organic solar cells that achieved a power conversion efficiency of 12.04%. These modules, designed for both light transmission and energy generation, are currently undergoing customer trials.
Why it matters
This technology offers a path for integrating power generation into materials that require transparency, potentially transforming how we utilize surfaces for energy. The development marks a step toward accessible, flexible energy harvesting solutions for future building applications.
In prototype testing, semi-transparent organic solar cells achieved a maximum efficiency of 12.04% for individual cells and 10.2% for fully printed modules. These results were validated through a collaborative project involving specialized research and manufacturing partners.
The players
Brilliant Matters
A Canadian company specializing in the development of organic photovoltaic materials.
HeiQ
A Swiss materials innovation firm focused on high-performance textile and functional surface technologies.
Forschungszentrum Jülich
A major German research center that operates the Solar Factory for renewable energy innovation.
The details
The modules utilize the BM10 organic photovoltaic platform paired with Xpectra silver nanowire electrodes to conduct electricity. By using roll-to-roll manufacturing, the materials are integrated into flexible substrates that maintain transparency. This stack allows the cells to function effectively while letting light pass through the device structure.
Timeline
October 8, 2026: The development of the solar cell technology was announced.
2028: Commercial availability of the technology is projected.
Health Landscape
This development aligns with the EU-funded Emerge project goals to transition toward more sustainable and integrated energy materials. It marks a shift from rigid silicon-based panels toward flexible, organic-based alternatives suitable for modern urban infrastructure.
While this technology is currently in the testing phase, it points toward future household applications that could reduce reliance on traditional power grids. Readers should monitor developments in sustainable home technologies to understand how these advances may impact energy costs and access.
The takeaway
Advancements in organic solar cells are bridging the gap between functional design and renewable energy generation. Keep an eye on the projected 2028 commercial rollout to see how these flexible materials might integrate into future building standards.
