In recent years, hybrid organic-inorganic perovskite solar cells (PSCs) have attracted significant attention as high efficiency, low temperature and low-cost fourth-generation photovoltaic. The power conversion efficiency (PCE) of PSC has been improved significantly, from 3.8% in 2009 to 25.5% in 2019 [1,2]. In this paper, numerical simulation of n-i-p configuration of Glass/FTO/ZnO/MAPbI3/Spiro-OMeTAD/Au perovskite solar cell using a one-dimensional Solar Cell Capacitance Simulator (SCAPS-1D) has been performed. ZnO is an alternative electron transporting layer to TiO2, due to their similar physical properties and excellent carrier transport. The effect of different parameters of the absorber layer and operating temperature on the photovoltaic performance of PSC such as the efficiency, the open-circuit voltage and the short circuit current density is studied. For an optimum thickness of 500 nm and defect density less than 1013 cm-3, we obtained a PCE more than 21%.
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.
