Abstract
This paper suggests a novel way to manufacture power-efficient building-integrated photovoltaic (BIPV) modules that are aesthetically acceptable for use in zero-energy buildings (ZEBs). An optical pattern is formed using additive manufacturing (AM) to maximize the number of sunrays that reach the solar cells and to hide cells beneath the pattern. The optical pattern was optimized by simulation, then selected PV modules were fabricated to ensure that they met the optimal optical pattern conditions. Increase in pattern angle and lens space yielded increase in the output power of the PV module, but reduced the aesthetic functionality. This color BIPV technology is expected to help expand the BIPV market and reduce carbon for “net zero” objectives.
Highlights
This paper presents a novel method to manufacture a colored PV module by using additive manufacturing (AM) so that the solar cells are not visible, and the efficiency reduction is minimized
Asymmetric Factor (As) PV module with optical patterns optimized for building-integrated photovoltaic (BIPV) applications was manufactured
Optical patterns with different pattern angles Θ and lens spaces S were implemented on glass, by using additive manufacturing using UV resins
