This attention is driven by their visual attractiveness and the opportunities they offer for integrating PV technology into diverse applications. However, limited color options and low efficiency restrict the widespread application of PV modules. This research introduces a targeted micropatterning strategy aimed at improving the efficiency and visual appeal of colored photovoltaic (PV) modules. This approach entails the selective elimination of black pixels from a multicolored pattern. By doing so, the surface area of the PV module is augmented, fostering enhanced light absorption and subsequently boosting output power. This study compares the performance of a selective micropatterned-based colored PV (SMPCPV) module with a reference black PV module, multicolored PV (MCPV), and a non-selective micropatterned-based colored PV (MPCPV) module. The characterization was performed in the outdoor environment where the result shows that the photoconversion efficiency (PCE) of the SMPCPV module is 11.36%. The selective micropatterning technique improved the PCE by around 18% compared to the 9.6% of the MPCPV module reported in a previous study and very close to the reference PV module (14.5%). The enhanced efficiency and aesthetically appealing SMPCPV module achieved in this investigation are pivotal in advancing future net-zero energy buildings and fostering a more sustainable environment.
