Paragraph starter
Research by Huang et al. (2015) demonstrated that replicating the complex surface structures of natural leaves onto polymer materials significantly enhanced light harvesting in photovoltaic systems, achieving up to a 17% gain in efficiency. This bio-inspired approach, utilizing a double transfer process, resulted in polymers with high optical transparency and haze, attributed to nano- and micro-morphologies that guided lightwaves and reduced reflection, suggesting a strategic direction for designing advanced light-harvesting covers.
