Hybrid inorganic-organic perovskite solar cells have been the spotlight in solar cells in the past few years. The long-term device stability and high power conversion efficiency are of crucial importantance for commercialization. In this report, we fabricate thiocyanate-based perovskite solar cells with chemical vapor deposition (CVD) method. Scanning electron microscopic image shows that SCN-based perovskite films via CVD have uniform morphology and large grain size at least 200 nm. These results reveal that the chemical vapor deposition can grow high-quality pseudohalide pervoskite films. For measuring the crystal structure of CH3NH3Pb(SCN)2I, the X-ray diffraction is employed to observe the characteristic peaks for both SCN-based and pure CH3NH3PbI3 pervoskite. The distinct peak of (110) at 14.16o for pure CH3NH3PbI3 is slightly shifted to 14.49o for CH3NH3Pb(SCN)2I. We suggest that the thiocyanate incorporates into perovskite crystal and distorts the lattice. The UV-vis spectra shows that the absorption onset of CH3NH3Pb(SCN)2I is identical with pure CH3NH3PbI3 at 780 nm. Moreover, we observe that the signal of photoluminescence(PL) for CH3NH3Pb(SCN)2I is at 770 nm. The higher radiative recombination energy level may produce higher open-circuit voltage(Voc)which is beneficial for high performance solar cells. Using Chemical vapor deposition method, we prepare SCN-based perovskite solar cells which produce a power conversion efficiency of 12.72%. These results demonstrate the pseudohalide perovskite solar cells are the promising material for improving stability and replacing pure CH3NH3PbI3 system.
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.
