Aesthetic Micropatterned Photovoltaic Glass for Net-Zero Buildings

Abstract

Integrating photovoltaic (PV) materials into building components represents a significant advancement toward achieving net-zero energy buildings (NZEBs). However, their widespread adoption is hindered by limited color and opacity options. In this study, we present a comprehensive experimental investigation into the color and transparency characteristics of PV modules, with a focus on their aesthetic appeal and photoconversion efficiency, utilizing advanced micropatterning techniques. Aperiodic micropatterned (AMPV) glass exhibits a lower haze of 3.7% compared to periodic types, which have a haze of 10.7%, while maintaining higher transparency at an AVT of 58.7%. Furthermore, a selectively micropatterned colored PV (SMPCPV) module achieves a power conversion efficiency (PCE) of 11.36%, surpassing both conventional single-color and multi-color designs. These advancements hold promise for the development of building-integrated PV modules that harmonize form and function for sustainable next-generation buildings
