Proceedings of International Conference on Perovskite Thin Film Photovoltaics and Perovskite Photonics and Optoelectronics (NIPHO26)
Publication date: 22nd April 2026
Perovskite–silicon tandems have reached an exciting inflection point, moving from record-e:iciency 1 cm2 laboratory cells to truly manufacturable devices on full-size industrial G12 wafers, opening a compelling pathway beyond the long-standing limits of single-junction silicon photovoltaics. In this talk, I will share our latest progress in bridging the gap between lab breakthroughs and industrial-scale production, focusing on the practical challenges that emerge during upscaling and the solutions we found to overcome them.
Key topics include wide-bandgap perovskite compositional engineering to unlock higher voltage and improved stability, achieving high-quality perovskite growth on textured silicon surfaces, and developing scalable deposition routes that span both solution-processing and vacuum deposition. I will also discuss how we address reliability under thermal and operational stress, an essential requirement for real-world deployment.
Building on these advances, we achieved a certified 32.2% power conversion efficiency on a G12 silicon wafer, the largest wafer format widely adopted in the PV industry today. We further demonstrated module-scale translation by fabricating a 1.52 m2 module based on the 32.2% G12H wafer, delivering a Pmpp output of 414 W, setting a new performance benchmark for perovskite-based modules. Encouragingly, these modules have also shown strong operational stability, maintaining performance over several months of field testing.
Overall, this presentation highlights our roadmap and confidence in translating perovskite–silicon tandems from outstanding lab results into high-yield, large-area manufacturing readiness, accelerating their path toward commercial adoption.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
