The increasing number of indoor appliances used daily has greatly accelerated the development of Internet of Things (IoT) technologies. However, this rapid expansion raises a major challenge: how to reliably power the increasing number of connected devices. Currently, most are battery-powered, which come with notable drawbacks, including frequent replacement, maintenance burdens, and environmental concerns related to their toxicity..
In this context, organic photovoltaics (OPVs) offer a promising alternative because of their energy-efficient production, lower environmental impact, and design flexibility. Notably, OPV devices have demonstrated high efficiency and excellent stability under indoor lighting conditions.
Consequently, indoor organic photovoltaics have emerged as a key candidate for powering low-consumption IoT devices across various fields such as electronics and sensing. It is therefore important to develop custom-designed photovoltaic devices to facilitate seamless integration into final products.
Inkjet printing has attracted considerable attention as a technology for large-scale fabrication of flexible and stretchable electronics due to its many advantages. It provides freedom in form and design on various substrates with good reliability, high time efficiency, low manufacturing cost, and reduced material usage compared to other deposition techniques.
These unique features have made inkjet printing an enabling technology for cost-effective production, drawing researchers’ interest in functional devices such as photovoltaic solar cells.
Nonetheless, several challenges remain, including ensuring ink stability to prevent nozzle clogging, controlling wetting properties, and matching ink viscosity and surface tension with printhead requirements.
In this work, we present fully inkjet-printed organic photovoltaic cells and modules with high efficiency, tailored for indoor applications, offering versatile shapes and designs, developed by Dracula Technologies.
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.
