Perovskite solar cells (PSCs) have rapidly emerged as a potential competitive photovoltaic technology reaching high power conversion efficiencies (PCEs)to a certified value of 23.7% within ten years. At this stage, the key issue is to improve long-term stability [1]. A promising direction toward improving perovskite phase stability is compositional engineering[2]. Thus, using lower amount of volatile methylammonium (MA) and more formamidinium (FA) can increase thermal stability. Lower Br/I ratios inhibits the disproportionate blue-shift of the bandgap [3]. In this work,by using the optimized perovskite composition and carbon cloth as a back contact, high PCE of 15% has been demonstrated where devices retain 60% of the initial PCE after 180 hours under 85 ºC and 40% relative humidity (RH) without any encapsulation and light soaking. The gold counterparts suffered from rapid degradation and retained 45% of the initial PCE at the same condition. In addition, the long term device stability of carbon based devices with different hole transporter material (HTM) revealed that poly[bis(4‐phenyl)(2,4,6‐trimethylphenyl)amine] (PTAA) is thermally more stable HTM than the copper thiocyanate (CuSCN) inorganic HTM (60% to 51%).
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.
