Perovskite Solar Cells have emerged only in the last decade and have experienced unprecedented interest and growth because of exceptional properties like high absorption coefficient, efficient charge carrier mobilities, solution processibility, low cost, and compatibility with roll-to-roll industrial processing. Amidst much anticipated potential and excitement around the fastest-ever-growing photovoltaic technology, challenges remain in understanding the fundamentals of charge carrier transport, material composition, and film growth dynamics. Moreover, degradation and instability remain one of the major issues impeding commercialization. Firstly, the work discusses some intriguing results that were yielded through the modifications made in the electron transfer layer (SnO2) of the solar cell devices with the chlorinated salts (Li, Na, and K) made in the classical structure of perovskite CH3NH3PbI3 [1]. Secondly, wide-bandgap compositions with CH3NH3PbBr3 and the mixed iodide-bromide system (CH3NH3PbIx Br1-x) as photoactive layers were studied to assess their viability in tandem solar cells. A substantial research component focuses on tracing these devices' degradation profiles. The performance and stability experiments attempt to utilize advanced and novel Spectroscopic procedures [2]. Finally, a few anomalous degradation pathways in the perovskite solar cells and observations made by integrating piezoceramic material in the photovoltaic architecture resembling the memory effect will be briefly introduced [3]. The insights developed will potentially assist in resolving some of the critical challenges in the field.

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.
