A review of the significance and challenges of building integrated photovoltaics

Abstract

The rise of innovative technologies in the built environment has witnessed a significant leap thanks to breakthroughs in research and development, applied science, and technology, as well as the global thinking towards a sustainable future. Beyond the international call and political mechanisms behind the current energy awakening is the challenge to clearly communicate the need for these innovative technologies. Building-integrated photovoltaics (BIPV) is a classic example of technological innovation, advanced by environmental demands, which has significant benefits. However, both existing literature and ongoing research show a gap between its technological growth and its global market diffusion. But what are the reasons? What economic, social, technical, educational or design-related barriers stifle the acceptance of innovative technologies like BIPV? This chapter presents a thought-provoking response by taking a holistic look at this issue to highlight not only the importance and the benefits but also the challenges associated with this technology. It justifies the ‘BIPV intervention’ from an energy and building dimension with relation to its strategic benefits, including the potential for improved energy generation. In the final section, focus is given to developments and challenges relating to the technical and non-technical aspects of the technology. As designers, educators, developers and decision-makers play a significant role in the adoption of innovative technologies, this chapter concludes with an outline of current needs and further research opportunities. These final thoughts are needed to chart a pathway for increased global acceptance and a sustainable built environment.
