Techno-economic analysis to determine the potential of perovskite-based PV blinds for buildings

Abstract

This paper analyses a novel perovskite-based Photovoltaic (PV) blind system for buildings. Some buildings are unable to install traditional solar systems because they cannot install PV panels on the roof or facade. Traditional PV materials have a long value chain, also the resulting solar panels are bulky and heavy and not suitable for blind applications. Recently, Perovskite crystals, a new semiconductor material, have shown potential for reducing the manufacturing cost while providing high energy conversion efficiency. However, a significant issue with PV blind systems is that they typically receive less solar radiation than traditional rooftop PV systems, resulting in less electricity generation, particularly when the PV blinds are used indoors behind the windows. In addition, unlike conventional rooftop PV panels, PV blind systems affect the total energy consumption in the building by changing the heating and cooling demands as well as interior lighting. Utilizing these new PV blind systems effectively necessitates a holistic analysis of solar potential, performance, and cost-effectiveness. In this study, whole-building energy simulation, techno-economical modeling, and parametric analysis will be used to compare perovskites PV blinds and conventional rooftop PV arrays.
