Summary
Is degradation of photovoltaic modules predictable and preventable? This project aims to determine the fundamental properties of the hydrogen related defect causing degradation of commercial solar modules and develop models to predict its impact. The defect causes up to 16% power loss and is likely to affect all photovoltaics due to the universal behaviour of hydrogen in semiconductors. Through new techniques combining deuterium (heavy hydrogen) and machine learning, the key project outcomes are ....Is degradation of photovoltaic modules predictable and preventable? This project aims to determine the fundamental properties of the hydrogen related defect causing degradation of commercial solar modules and develop models to predict its impact. The defect causes up to 16% power loss and is likely to affect all photovoltaics due to the universal behaviour of hydrogen in semiconductors. Through new techniques combining deuterium (heavy hydrogen) and machine learning, the key project outcomes are new knowledge of hydrogen behaviour, mitigation of degradation and predictive models to test and forecast the future output of affected modules. This is critical for system design and reliability, manufacturer warranty terms, investor returns, consumer confidence, and ultimately mitigating the climate crisis.Read moreRead less

Summary
Hydrogen passivation mechanisms in silicon solar cells. This project aims to understand hydrogen passivation mechanisms in silicon solar cells. Most silicon solar cells use low-quality wafers with defects that can reduce performance by >10%. Commercial devices use hydrogen to passivate defects and improve performance. Despite decades of research, these passivation mechanisms are controversial and industrial methods are ineffective.

This project aims to understand hydrogen passivation mechanisms in silicon solar cells. Most silicon solar cells use low-quality wafers with defects that can reduce performance by >10%. Commercial devices use hydrogen to passivate defects and improve performance. Despite decades of research, these passivation mechanisms are controversial and industrial methods are ineffective. This project will investigate hydrogen charge-state control and transient hydrogenation processes, and correlate reaction rates and material properties. This should improve the understanding of hydrogen passivation mechanisms and lead to more effective hydrogenation processes that potentially reduce greenhouse gas emissions and the cost of sustainable electricity.Read moreRead less

Advanced Recombination-based Loss Analysis Methods for Solar Cells. Photovoltaic (PV) solar cells are too expensive to become a viable solution for the challenges facing humanity. Increasing solar cell efficiency can reduce the cost of PV-generated power. Improved efficiency requires the ability to identify and quantify loss mechanisms, many of which are recombination related.

Photovoltaic (PV) solar cells are too expensive to become a viable solution for the challenges facing humanity. Increasing solar cell efficiency can reduce the cost of PV-generated power. Improved efficiency requires the ability to identify and quantify loss mechanisms, many of which are recombination related. Thus, innovative analysis methods need to be developed to facilitate improved understanding and identification of various loss mechanisms. The project aims to investigate recombination processes that deteriorate solar cells performance, using a novel measurement system in combination with advanced simulation tools. The project aims to assist with development of advanced processes to improve device performance.Read moreRead less

The project aims to develop new solar cells made of low cost abundant elements. The cells are cadmium-free copper zinc tin sulphide (CZTS) cells formed by rear contact passivation and damage-free evaporated front layers. CZTS has the same efficiency potential as current commercial copper indium gallium selenide (CIGS) cells, but consists of low cost, abundant elements. Concepts and methods will be developed for passivation of CZTS solar cells via both back and front contact engineering. The cadmium- free buffer layer will be investigated and the application of CZTS will be expanded. This work may be applied to CIGS improvement and could give CZTS materials a significant role in the rapidly growing photovoltaic industry.Read moreRead less

Summary
Nervous tissue stimulation using Multi-Junction Silicon Photodiodes. Currently, in order to stimulate different areas in nervous tissue, brain-machine-interfaces (BMIs) usually rely on multi electrode arrays where each electrode is connected to a wire, that connects to other electronics, all of which has to be safely encapsulated, thus increasing the size of the devices and complicating the surgical procedure for implanted devices.

This project aims to develop a silicon multi-junction photodiode that can provide a photovoltage high enough to efficiently excite nervous tissue. A BMI based on this approach could be much smaller and could be powered optically via thin fibres, thus in the long run enabling smaller and safer implants for restoring function in disabled people.Read moreRead less
