Enhancing Solar Panel Efficiency through Wide-Angle Anti-Reflection Technologies
Maximizing solar panel performance requires optimal installation angles, yet challenges arise when sunlight hits the panels at angles greater than 55 degrees for around 30% of the time, leading to significant reflections. This work explores the application of nanotextured anti-reflection technologies to mitigate losses especially at wide angles. We present a new generation of moth-eye nanotexturing that creates a gentle gradient in the index of refraction for transmitted light, no matter the wavelength and angle of incidence. Across diverse geographic and climate conditions, this novel approach to anti-reflection can enhance annual solar panel power output by 5-6% for optimally tilted panels and up to 12% for building-side mounted vertical panels such as those used in urban integration. Our work demonstrates how wide-angle anti-reflection technology can advance solar energy efficiencies on a global scale.
