With the sharp increase in global energy demand, nowadays, around 40 % of energy is consumed by industrial and residential buildings with most of the supplied energy being from nonrenewable sources that significantly contribute to global warming and environmental hazards. The net-zero energy building (NZEB) concept attempts to solve the issues where a building will produce, on-site, its required energy demand throughout the year from the renewable energy sources. This can be achieved by integrating photovoltaic (PV) building materials, called building-integrated photovoltaic (BIPV), throughout the building skin, which simultaneously act as construction materials and energy generators. However, architects are not currently encouraged to design a building using BIPV modules due to their limited colours, namely black or blue, which result in a dull appearance. Therefore, the development of aesthetically appealing BIPV products is necessary for architects and building owners to consider their deployment in modern green buildings.
My PhD project aims to develop aesthetically attractive BIPV products, namely semitransparent PV glass and high-definition coloured PV modules, which serve both purposes of building materials and on-site electricity generators. This project will develop semitransparent PV glass by applying the laser engraving technique on thin-film PV modules based on quasi-periodic micropatterning. Also, high-definition coloured PV module will be developed by direct micro-resolution printing on thin-film PV modules. These PV products will be characterized using haze meter, UV-vis-Spectrophotometer, stylus profilometer, and a sun simulator. This project will provide aesthetic BIPV modules using a very simple and cost-effective printing technique (UV flatbed and/or ceramic printers).
The outcomes of this PhD project will have a significant impact on building construction, outdoor advertisement, roads and highways, PV cars and solar greenhouses and open the way for the development of BIPV solutions that potentially contribute to reducing global warming (Carbon footprint) and environmental hazards.
