Inverted perovskite solar cells consisted of ITO (Indium tin oxide) / NiOX (Nickel oxide) / FA0.84Cs0.12Rb0.04PbI3 perovskite (FA+ = Formamidinium ion)/ Additive /C60 / BCP(Bathocuproine) / Ag have been investigated and are highly stable for continuous 1 SUN illumination [1]. The role of additive at the interface of perovskite/ Additive /C60 (Electron transport layer) on the photovoltaic performance has been discussed [2-4]. In case of pentafluorophenylhydrazine (5F-PHZ) as additive, 5F-PHZ construct 2-dimensional (2D) perovskite grains at the interface [1]. Almost of other additives should interact with the vacancies of A or X site of ABX3 perovskite where A= methyl ammonium ion or FA+, B = Pb2+, X= Cl—, Br—, and I—. To explain the role of the additives, we choose ionic additives A+X—, where A+ and X— interact with vacancies of A and X sites of perovskite, respectively. We assumed that the vacancies of X— should not so influence on the charge recombination because the vacancies of X— moves as ion migration in perovskite layer with lower activation energy of ~0.3eV [5]. Therefore, we fixed the size of X— anion which is larger than the size in tolerance factor and selected various size of A+ cation. We estimated not only current density (J) – voltage (V) curves of these devices with various ionic additives but also the internal quantum efficiency (IQE) of the perovskite solar cells by measuring the external quantum efficiency (EQE) and reflectance spectroscopy.

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.
