Ultra-Porous Devices by Synergistic Aerosol and Atomic Layer Depositions. The project aspires to develop a scalable low-cost approach for the synthesis and integration of ultra-porous films in nanodevices. The project intends to deposit atomic layers onto aerogel-like nanoparticle networks, self-assembled by thermophoresis of flame-made aerosols.

The project aspires to develop a scalable low-cost approach for the synthesis and integration of ultra-porous films in nanodevices. The project intends to deposit atomic layers onto aerogel-like nanoparticle networks, self-assembled by thermophoresis of flame-made aerosols. This would increase the atomically-deposited layer mass by several hundred-fold per cycle and result in ultra-porous films with electrochemically active surface areas. It is intended that the project will demonstrate the fabrication of solid–gas, solid–liquid and solid–solid nanointerfaces, which will be applicable to key emerging technologies such as wearable medical diagnostics.Read moreRead less

This project aims to develop a high-efficiency indoor photovoltaic (PV) technology to provide reliable low-cost power in the multi-billion dollar “Internet of Things” (IoT) market. There are currently no devices that meet the requirements for maximum operating efficiency under indoor illumination. We propose to solve this problem by fabricating PV cells using colloidal perovskite quantum dots that offer class-leading stability and band gap tunability across the required range, enabled by quantum confinement. The outcome is the development of integrated self-powered IoT devices potentially impacting Advanced Manufacturing growth in Energy, Cyber Security, Food and Agribusiness, as all of these will ultimately rely on networked smart devices.Read moreRead less
III-V semiconductor nanowire solar cells without p-n junctions. This project proposes a new class of nanowire solar cells that do not rely on conventional electrical (p-n) junction for photo-generated charge carrier separation.

This project proposes a new class of nanowire solar cells that do not rely on conventional electrical (p-n) junction for photo-generated charge carrier separation. Instead the band structure of the semiconductors is engineered to form a misalignment which leads to the spatial separation of carriers. This approach is expected to fundamentally change the design of solar cells, eliminating the technologically challenging need for forming good electrical junctions, while retaining all advantages inherent to III-V semiconductor nanowire solar cells. More importantly, the device concept proposed is expected to have implications for a wider class of solar cells based on exotic/novel materials or nanostructures where achieving both n- and p-doping may be challenging.Read moreRead less

Hot carrier solar cells: new approaches and demonstration of devices. The hot carrier solar cell aims to capture a large fraction of energy from solar photons normally lost as heat. This will give much higher efficiencies, and allow fabrication of cheap high efficiency devices. This can be achieved by modifying the way electrons lose their energy as heat, by blocking the lattice vibrations which cause this loss.
