Ymchwil

Fy maes ymchwil yw PV tenau wedi'i argraffu â ffilm gydag arbenigedd mewn datblygu technolegau newydd ar gyfer cynhyrchu ffotofoltäig newydd gan gynnwys prosesau dyddodi a halltu a'u nodweddu gan ddefnyddio dulliau electrocemeg, ffotogemeg neu optoelectroneg.

Ar hyn o bryd mae dadeni mewn ffotofoltäig printiedig ffilm denau ac yn nodweddiadol mae'r datblygiadau hyn yn byw yn amgylchedd y labordy ar hyn o bryd. Fy nod ymchwil yw cymryd y setiau deunydd hyn a datblygu'r linell weithgynhyrchu ar gyfer gwneuthuro ar raddfa. Defnyddir dull tair darn i gyflawni'r diben hwn (i) penderfynu ar fecanweithiau colled sy'n gysylltiedig â graddfa - gostyngiadau mewn perfformiad wrth gynyddu o raddfa labordy i raddfa beilot. (ii) Mynd i'r afael â tagfeydd proses i leihau amser gwneuthuro (iii) Cyfieithu pensaernïol - sicrhau'r ystod ehangaf o swbstradau trwy adeiladu dyfeisiau ar wydr wedi'i brosesu â dalennau metel neu blastig.

Yn benodol, mae fy ngweithgaredd ymchwil yn cynnwys gorchuddio a halltu deunyddiau ffotograffig, cynhyrchu dyfeisiau PV ar raddfa labordy ac is-fodiwl ynghyd â nodweddu deunyddiau ffotograffig trwy ddulliau electrocemegol ac optoelectroneg. Mae'r ymchwil yn ymestyn ar draws nifer o wahanol dechnolegau: celloedd solar 'dye-sensitized' wedi'u seilio ar hylif, celloedd solar solid 'dye-sensitized', organolead halide perovskitesperovskites ac yn fwy diweddar kesterite CZTS (Cu2ZnSnS4).

Addysgu

  • EG-108 Engineering Sustainability

    .

  • EG-183 Materials Resources

    Materials resources are and always have been a controlling factor in economic and social human development. This course assumes no prior knowledge and explores the development of materials exploitation from the earliest times illustrating how the availability of resources and the ingenuity of humankind to exploit and extract new materials has allowed the evolution of our modern world. In historical terms, materials exploitation has always been related to economic growth or military needs. Increasingly, sources of energy and materials are sought which are both economically attractive and sustainable. As such, in each section of the course, aspects of sustainability and economics will be addressed, to show how and why certain materials choices are made for specific applications.

  • EG-279 Functional and Smart Materials

    This module covers the underlying scientific principles behind the physical properties of functional and smart materials. It provides the basis for electrical conductivity, semiconductivity, superconductivity as well as optical, magnetic and thermal properties. The ways in which these properties can be utilised in a wide range of devices is explored. Module Aims: to introduce the scientific principles behind the physical properties of functional and smart materials and to explore the manufacture of functional devices.

  • EGTM99 Functional Coatings

    Historically coatings have been relatively benign with developments focussing on increased lifetime or greater control of colour and adhesion. In recent years industry and society have demanded increased functionality for coatings and no more so than in the world of construction. Every year millions up millions of square meters of painted cladded material is produced in the UK. By functionalising just a small percentage of this output to generate, store and release energy it is possible to have a huge impact in the energy and climate challenges set by government. This module will furnish the students with information and knowledge on the various photovoltaic technologies under development, paying particular attention to technologies that utilise earth abundant, environmentally friendly materials. The course will require students to make a solar cell in the laboratory and perform measurements on its efficiency.
