ABSTRACT: Organo-metal trihalide perovskites have revolutionized the field of thin film solar cells due to their meteoric rise of power conversion efficiency (PCE) of a record value over 22%.1 The advantage of perovskite material is low-cost precursors, and capable of being processed a variety of scalable methods.2-3 Despite impressive photovoltaic performances of perovskite solar cells, most reported devices are not stable under operation. Here we report stable perovskite solar cells by engineering an ultra-stable 2D/3D HOOC(CH2)2NH3)2PbI4/CH3NH3PbI3 perovskite junction. The 2D/3D perovskite films are produced in a single step from the solution containing a mixture of 3% HOOC(CH2)2NH3I, methylammonium iodide and PbI2. The composite mixture self-assembles into gradually organized multidimensional structure that yields up to 14.6% employing mesoporous TiO2 and spiro-MeOTAD as electron and hole specific contacts, respectively. The XRD and photoluminescence analysis demonstrate the unique role of the 2D perovskite, anchored at the interface with the oxide nanoparticle network, in templating and stabilizing the 3D CH3NH3PbI3 phase. The resulting 2D/3D metal halide perovskite solar cells in a hole-conductor free architecture exhibit a record stability under AM 1.5 sunlight. Also, we address hysteresis by using molecularly engineered novel hole transporting materials.4

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.
