Flexible perovskite solar cells (f-PSCs) have great potential prospects in flexible energy and mobile energy systems. Rigid PSCs have made important progress, and the power conversion efficiency (PCE) has exceeded 25%, but the PCE of f-PSCs is still much lower than rigid ones. Based on the device structure of PEN/ITO/SnO2/FAMAPbBrxI3-x/Spiro- OMeTAD/Ag, the PCEs up to 19.51% were achieved through the precise control on electron transport layer SnO2[1]. Furthermore, CF3PEAI molecule was introduced to construct 2D perovskite modified layer between 3D perovskite and hole transport layer[2]. It could passivate 3D perovskite film defects, adjust energy level structure between perovskite and hole transport layer and improve 3D perovskite charge transport performance, leading to the PCEs up to 21.1% (verified PCE was 20.5%). The f-PSCs exhibited excellent stability and bending resistance. Meanwhile, based on ink formula regulation and interface optimization, efficient f-PSCs were fabricated by roll-to-roll printing process, showing potential application prospects [3].

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.
