Indoor photovoltaics (IPVs) is expected to be widely applicable to operate low-power Internet of Things (IoT) electronics used in indoor environment, which makes IPVs attractive as an emerging sustainable energy harvester. Among various photovoltaic materials, perovskites exhibit promising indoor power conversion efficiency (iPCE) because of their compelling optoelectronic advantages over the other materials.
In this study, we developed a simple and effective interface treatment of perovskite solar cells (PSCs) for improving iPCE under low-intensity LED light. We passivated traps at the surface of electron transport SnO layer by layering RbI. This treatment significantly reduced charge recombination at the SnO/perovskite interface, which enabled considerable enhancement of iPCE of PSCs from 32.12 to 35.13 % under 1000 lux LED. More specifically, through systemic characterizations we systemically revealed that reduced interface recombination improved open circuit voltage and charge extraction property at indoor light illumination condition. These findings suggest that simple interface treatment using RbI can be a useful strategy for the iPCE optimization of indoor 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.
