This proposal is an interdisciplinary research project that focuses on the study of integrating next generation nanoscale solar skin in order to reduce the solar heat gain and glare while producing electricity. Building envelope is one of the most important design parameters determining indoor physical environment related to thermal comfort, visual comfort and even occupancy working efficiency, thus affecting energy usages in buildings. As the desire for a fully glazed façade and higher transparency among designers is growing, the environmental impact, problems of heat losses, summer overheating and glare are issues of increasing concern. The task is to find a way to automatically resolve these issues without compromising aesthetics of the façade and occupant’s comfort while simultaneously generating power.
The proposed novel bio mimicry approach inspired by the principles of photosynthesis in plants will be used to maximize light harvesting in a silicon micro wire array in an integrated adaptive façade. The primary objective of this research is to carry out a feasibility study of an integrated nanosolar façade system by exploring its performance, and fabrication challenges.
The primary goals of the nanoskin façade design research are as follows:
- developing the nanoscale responsive skin material, and carry out a performance assessment in the area of energy demands and energy production potential.
- investigate the possibility of integrating the prototype in different forms and applications of building façades, and mobile applications because they offer novel approaches for solar-to-electric energy conversion leading to high-efficiency devices via simple manufacturing and transportation. The nanosolar skin thin film does not block the views and does not impact on the aesthetic aspects.
- Fabricate a 1:1 nanosolar skin prototype developed from performance-based design strategy
The investigators will develop an adaptive system prototype that integrates silicon wire photovoltaics that will respond to the solar light intensity on a façade. These types of nanowire devices have been produced previously, however, the new important element will be the use of thermoresponsive polymers to effect the silicon wire orientation making the film opaque.
