Lead Halide Perovskites: Synthesis, Properties & Applications in Hybrid Optoelectronic Devices
No full textThe introduction of photovoltaic cells and light emitting diodes has defined this era of technology. Together they provide affordable renewable energy and high efficiency lighting. Despite all these benefits, current solid state materials are rapidly approaching theoretical device limits and will soon be unable to meet rising demands. In 2009, through a fusion of wet chemistry and nanotechnology, lead halide perovskite dots were identified. These novel materials exist as nanocrystalline semiconductors with bright, tunable absorption and emission wavelengths. As a result, perovskites are an intriguing candidate to work in tandem with solid state materials, promising to elevate device performance and efficiency. While an attractive prospect, such a combination is not without the significant challenges of material compatibility and stability, which must both be overcome to create a successful device. This thesis presents an overcoming of these obstacles by undertaking a detailed investigation of perovskite nanocrystals. Expertise in perovskite nanomaterials is developed to further their nanochemistry and optical properties with dramatic increases in photochemical lifetime obtained using polymeric encapsulation methods. The most promising candidate is then improved and brought to application in a device, resulting in a 100 % increase of Power Conversion Efficiency at UV wavelengths in a photovoltaic cell
Reuse in context: <i>SHIRT</i> [workshop]
No full textIndividuals’ decisions regarding their possessions have wide implications in terms of resource efficiency and environmental impacts. With reference to a specific example – a used item of clothing – this workshop seeks, through structured discussion, to gain insight as to how and why individuals make decisions regarding when personal possessions reach the end of their useful life and the fate of such items thereafter

No full textReuse in practice: the UK’s car and clothing sectors
No full textOngoing efforts to seek better resource efficiency have highlighted the role of reuse as a contributor to achieving circular economy objectives. In order to improve resource efficiency, the motives, means and opportunities for reuse need to be understood such that best practice can be identified and measures implemented to foster more effective and more extensive reuse. This study compares and contrasts reuse in the car and car components sector with the clothing sector as a means to identify commonalities and differences, and seek facets of effective practice. The car sector is found to align more with financial motives than the clothing sector, the latter providing more marked and apparent social benefits. Three key aspects appear common to both sectors. First, whole lifecycle – cradle to cradle – approaches to enhancing reuse are emerging and have considerable merit from a circular economy perspective. Secondly, the internet has become a key tool for the facilitation of reuse and is likely to grow further in this regard. Thirdly, decisions regarding the end-of-use of consumer products are critical and need to be better understood. Fourthly, for any reuse initiative to deliver positive outcomes, consumers must be fully engaged. We conclude that whilst some sector-specific adjustments may have to be implemented in future initiatives to promote and enhance reuse activities, the overarching principles and optimum methods of reuse facilitation may well be common for contrasting sectors
