Накратко на български

Фотоволтаичните клетки от галий-арсенид върху силикон се изследват за захранване на безжични сензори чрез околната светлина в сгради. Това помага за намаляване на разходите за смяна на батерии и подобрява автономността на устройствата в умните сгради.

Photon-recycling for high-efficiency energy harvesting in GaAs photovoltaic devices on silicon

Billions of wireless sensors are expected to be installed over the coming decade, with almost half to be located inside buildings. Due to the limited lifetime of batteries, this vision will not be realised without energy harvesting solutions providing power autonomy to sensors, a topic specifically prioritised in the 2016-2017 Work programme of Horizon 2020. Currently, the use of batteries to power these devices places significant constraints on their power consumption, where the range and frequency of data transmission are curtailed to achieve sufficient battery life, and the range of applications is also limited to the ones that allow battery replacement. Additional operation and maintenance costs are also incurred by providing replacement batteries. Indoor photovoltaics has the potential to solve these hardware issues, providing greater reliability and operational lifetimes in wireless sensor networks. Persistently powering individual nodes by harvesting ambient light using small ∼cm2 photovoltaic cells is becoming possible for more and more wireless technologies and devices. In this project, we characterize the performance of various indoor photovoltaic cells under ambient light sources. Given the interest in commercializing different photovoltaic cells in this growing market, we have also built techno-economic models to compare different technologies and tackled the outstanding research questions that must be answered by the indoor photovoltaic community to enable self-powered, indoor-located IoT nodes. If successful, this project will enable the deployment of wireless sensors at scale to generate the Big Data required to optimize operations and increase efficiency across many industries primarily located indoors such as energy-efficient and smart buildings, logistics and inventory sensing and tracking, health monitoring, or robotic systems. In order to widely deploy wireless sensors for indoor applications, we are investigating the manufacture of devices that are low-cost, self-powered, easily deployable at scale and could remain operational for many years.

Цел на проекта

The Internet of Things promises billions of connected sensors and devices measuring and reporting information about the world around us. Due to the limited lifetime of batteries, this vision will not be realised without energy harvesting solutions providing power autonomy to sensors, a topic specifically prioritised in the 2016-2017 Work programme of Horizon 2020 (page 100). This project aims to develop and demonstrate high-efficiency and low-cost GaAs photovoltaic energy harvesters as power sources for wireless sensors, and equip the fellow with the entrepreneurial competencies required to commercialise the results. Prof. Tonio Buonassisi’s photovoltaic research lab at MIT (PVLab) is a global leader in optoelectronic modelling and testing of novel photovoltaic devices, and will train the candidate to determine the technical and economical viability of this new technology. The growth of these novel devices will be carried out with Mr. Brian Corbett in the III-V materials and devices group at the the Tyndall National Institute, Ireland. During the outgoing phase, as well as training in technical competencies, one-day a week will be dedicated to attending MIT’s Translational Fellows Programme, a specialist course for entrepreneurially-minded postdocs, teaching venture creation in-line with the candidate’s career goal to be an EU leader in science-based entrepreneurship in the clean energy sector. On return to the EU, a secondment at IQE plc., a III-V foundry, will allow the economic aspects of producing these devices in industry to be explored.
