Perovskite solar cells based on an all printable mesoporous stack, made of overlapping titania, zirconia and carbon layers (C-PSC), represent a promising device architecture for both simple, low cost manufacture and outstanding stability. In this talk we will report on a breakthrough in the upscaling of this technology: a recent pilot scale trial of 20 screen printed A4 sized FTO-glass substrate perovskite modules, delivering power conversion efficiency (PCE) ranging from 3 to 7% at 1 sun on an unprecedented 198 cm2 active area.
The current fabrication process for a C-PSC is a highly manual and time consuming batch process designed on single monolithic devices. This work will introduce a number of engineering solutions to unlocking pilot scale manufacture; (i) overcoming long manufacturing times, reducing the total time from 3 hours to 30 seconds. (ii) replacing manual drop infiltration of the perovskite with a novel robotic method that enables large area, instantaneous and homogeneous deposition of perovskite droplets over the active area and finally (iii) enabling series connection and an increase in geometric fill factor of the modules using both mechanical and laser scribed interconnection processes.
The paper will also discuss the overall experience both good and bad of planning and delivering a pilot scale fabrication run of multiple perovskite modules.
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.
