We present a second-generation hole transporting materials capable of forming a self-assembled hole-selective monolayer (SA-HSM).
Perovskite p-i-n architecture solar cells with the second generation SA-HTMs demonstrated very promising power conversion efficiency close to 21% and average fill factor of over 80%. Due to the excellent bonding to the substrate surface, these layers are relatively tolerant against perovskite processing and can ensure a conformal coverage of textured surfaces. Application of the developed materials in tandem perovskite/silicon solar cells resulted in record 29.15 % efficiency devices.
Forming SA-HSM on the transparent electrode circumvents the disadvantages of spin-coating while offering the benefits of uniformly formed layers with minimized thickness, very low material consumption (1 g of the material is enough to cover up to 1000 m2 of the surface) and helps to avoid doping procedures. The materials are commercially available from Tokyo Chemical Industry Co., LTD or Dyenamo AB.
These materials were developed for the application in perovskite solar cells, however ease of structural modifications and use of versatile anchoring group opens the path for application in other areas as well, for example quantum dots and quantum dot-based devices.
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.
