Proceedings of International Conference on Perovskite Thin Film Photovoltaics and Perovskite Photonics and Optoelectronics (NIPHO25)
Publication date: 24th April 2025
To fabricate and eventually scale highly efficient perovskite-silicon tandem solar cells it is crucial to deposit perovskite thin-films of high quality reliably onto industrial silicon solar cells. To do this we employ several evaporation techniques such as co-evaporation, sequential evaporation, and the hybrid route which combines evaporation with wet-chemical deposition techniques. Each of these has its own challenges and opportunities. In this talk I will share the insights we have gained into the growth mechanisms, crystallization behavior, and the influencing factors that govern the evaporation of different perovskites.
We implemented these perovskite films into tandem solar cells reaching efficiencies above 31% on 1 cm² cells. I will discuss the modeling and optimization steps that were taken to improve the whole tandem stack and achieve these results. These high laboratory efficiencies now motivate our efforts to take these devices from laboratory to large-scale production. For this purpose, we are also developing and optimizing large area deposition methods for the contact and passivation layers of the solar cell. We are also pursuing device architectures that go beyond dual junction tandems to realize triple junction solar cells utilizing silicon and perovskite layers, which offer an even higher efficiency potential. I will present the progress we have made in that endeavor.
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.
