Perovskite solar cells (PSCs) have achieved remarkable power conversion efficiencies (PCEs) of 25.7% on single-junction PSCs and 29.8% on perovskite-silicon tandem solar cells. Recently, scalability has also been well addressed by manipulating the perovskite crystal growth, investigation of device engineer as well as optimization of up-scaling techniques. However, the operational stability of the device is still not good enough to compete with other well-established PVs.
It is reported that degradation of the device always starts from the interfaces. Therefore, we are dedicated in designing and investigating different passivation materials as well as solvent engineering at the interface between the perovskite and hole transporting layer, in order to improve the device performance and most importantly, their operational stability. As a result, our target devices treated by various interfacial passivation materials delivered PCEs approaching 24% with excellent long-term stabilities, especially under maximum power point tracking of over 1500 h with retaining more than 96% of their initial PCEs.[1-4]
The projects have received funding from the European Union's Horizon 2020 research and innovation program under grant agreement No 764047 and from the Swiss National Science Foundation for financial support with Project No. 200020_185041.
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.
