Intel corporation predict that by the end of 2020, up to 200 billion connected Internet of Things (IoT) devices came online and this is predicted to consume over 1000 TWh yr-1 by 2025. To put this in perspective, this is over 1300 x the energy output of EU’s largest solar plant, Núñez de Balboa. The increasing digital interconnectivity of our everyday lives means that this energy burden will only increase in the coming decades. In addition, many portable IoT devices incorporate primary batteries, which consume valuable materials. One solution to this growing demand is the coupling of IoT nodes with energy harvesting devices, such as photovoltaics cells which could provide power to IoT nodes and avoid the need to replace primary batteries.
Hybrid solar cells such as perovskites, OPVs and DSSCs, have all shown promising performance in ambient light, meaning that any of these technologies could be candidates to power future IoT devices. Despite the promise of these PV technologies, work needs to be done especially around standards for testing. There is currently no consensus on what constitutes “ambient light” both in terms of spectral and power output and it is difficult to compare results from one laboratory to the next. We can predict the path of the Sun for any given point on Earth, but predicting how much light power is available in any given ambient scenario is difficult and reliant on human factors such as available light sources (e.g. CFT, LED, natural, or combination) and position of the solar cell relative to the light source.
This presentation will explore these issues, showing the results of maximum power measurement in real and simulated scenarios and how in some cases, an IV curve measured at single lux value is not an accurate predicator of real-world performance. Module design will also be discussed in relation to series resistance at low light intensity and how this may be able to reduce module costs. Finally, the presentation will explore some ideas from the field of Human-Computer-Interaction (HCI) showing the result of collaborative work whereby hybrid solar cells not only provide power to IoT nodes, but also provide means of user interaction and control of the technologies themselves.
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.
