Because of their ideal band gap for all-perovskite tandem solar cells and high efficiency single junction solar cells, mixed lead-tin perovskites have recently received a lot of attention [1]. Currently, the hole transport layer (HTL) most commonly used for lead-tin perovskite solar cells is poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS). However, this hygroscopic material has been shown to cause long term stability issues in devices, so many research groups have started using self-assembled monolayers (SAMs) of small organic molecules, like [2-(9H-carbazol-9-yl)ethyl]phosphonic acid (2PACz), as an HTL instead. [2] This study aims to find mechanistic insights into the differences in performance and stability caused by these different transport layers. To do this, we investigate the evolution of the performance of mixed lead-tin perovskite solar cells over time during continuous illumination, using either PEDOT:PSS or 2PACz as an HTL. We find clear differences between the stability of PEDOT:PSS-containing and 2PACz-containing devices, for measurements both in inert atmosphere and in ambient air. We also study the photoluminescence and photoluminescence lifetime of these devices, to probe their optoelectronic properties. We aim to link the observed differences in performance and stability between these two different HTLs to optoelectronic properties of the devices as derived from photoluminescence and photoluminescence lifetime data.
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.
