Proceedings of International Conference on Hybrid and Organic Photovoltaics (HOPV18)
Publication date: 21st February 2018
Lead-based perovskite solar cells (PSCs) have exceeded power conversion efficiencies (PCEs) over 22%. In order to fabricate PSCs on flexible substrates, the substrate needs to endure several fabrication related conditions (high temperature, corrosion and flexibility). Coated steel substrate is a suitable candidate to overcome these challenges and desirable for building integrated photovoltaics.
Here we present the development of a PSC fabricated in the following sequence: coated steel substrate/gold bottom electrode/SnO2/PCBM/perovskite/spiro-OMeTAD/MoO3/gold/polystyrene. The dielectric/metal/dielectric top electrode stack was optimized using optical simulation and tested both on semitransparent and gold metal bottom electrode device architectures. By employing polystyrene as the top dielectric in the top electrode stack, the light incoupling can be greatly enhanced enabling PCEs up to 11.4% for PSCs on coated steel substrate. Our optical loss analysis highlighted that the generated photocurrent of these PSCs is mainly limited by the parasitic light absorption originating from the hole transport material and the transparent top electrode stack.
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.
