Dye-sensitised solar cells have recently attracted increasing interest as devices for ambient light harvesting, with reported efficiencies now reaching 37% under indoor light [1]. A remaining challenge however is the comparatively poor stability of devices containing a liquid electrolyte. One approach to overcome this involves drying of the Cu-complex based electrolyte to give a solid-state, so-called “zombie”, cell [2]. Although these can reach good efficiencies, the drying process is currently slow and poorly reproducible, thus impractical for real-world use.
We have fabricated solid-state DSSCs by simply drying out the common liquid I-/I3- electrolyte [3], and have demonstrated power-conversion efficiency for the solid-state cells over 5%, similar to that of the parent liquid cell before drying. In indoor light conditions (1000 Lux), power-conversion efficiencies were around 20%. We observed negligible degradation of efficiency after 12 months dark storage without encapsulation. Furthermore, we have developed a rapid process for cell fabrication, enabling larger area devices made on an open bench [4]. We believe these findings establish a unique new approach to making very simple, stable, solid-state DSSCs of potential practical application, with efficiency that might be optimisable up to around 10%.
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.
