In the recent years the interest in perovskite solar cells rises immensely, due to the easy synthesis method, the matching band gap and the cheap precursors.[1],[2] But the major lays on the preparation of thin-film solar cell by spin coating technique. Only a few groups investigate perovskite nanoparticles.[3],[4]
Withal are nanoparticle an interesting material for a solution based “one step” solar cell production. Due to the from the device separated synthesis of perovskite nanoparticles, the resulting nanoparticles is i.e. easier to purificate. Further more, the perovskite nanoparticles are easy to synthesize and the properties are scalable. The perovskite nanoparticles could be adjusted by the choice of a fitting surfactant for a layer formation on the selective electrodes. We are investigating the optical and electrical properties of CH3NH3PbBr3 perovskite nanoparticles and their layer formation. Our interest lays on the layer formation of nanoplattlets in layers and on the layer formation of the nanoplatletts on titan dioxide nanoparticles. The composite nanoparticle system could be used for a simple bulk-heterojunction solar cell.

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.
