Inverted perovskite solar cells (PSCs) have attracted great attention due to their low fabrication cost, high performance, and negligible hysteresis. To achieve their commercialization, many researchers on inverted PSCs have been tried to improve the power conversion efficiency over the past few years. It is extremely important to develop high-quality hole transport layer (HTL) for fabricating inverted PSCs with highly performance. This work describes a facile, one-step, solution process method for the preparation of zinc-doped nickel oxide (Zn-doped NiO) hole transport layer for efficient PSCs. Inverted PSCs with the configuration of FTO/Zn:NiO/Cs0.05FA0.81MA0.14Pb(I0.90Br0.10)3/PCBM/BCP/Ag were fabricated and evaluated. We detected that a Zn-doped NiO hole transport layer can directly effect growth dynamics of perovskite on HTL layer (from SEM images). Also, photoluminescence results, we found that Zn-doped NiO hole transport layer improved the hole extraction efficiency due to reduced defect states. As a result of all these improvements, we report Zn-doping strategy for NiO improves photovoltaic performance of inverted PSCs.
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.
