Innovation Summary:
This invention introduces a photovoltaic material enhanced with photonic crystal structures to increase light absorption. The surface features inverse conical structures with Gaussian-shaped sidewalls that trap and redirect light into the active layer. This design significantly improves the efficiency of solar cells, particularly under diffuse lighting conditions. The material is suitable for integration into next-generation solar panels and other photovoltaic systems.
Challenges / Opportunities:
Improving solar cell efficiency without increasing cost or complexity remains a major challenge in renewable energy. Traditional flat-panel designs lose energy due to reflection and limited light trapping. This invention addresses those issues with a novel surface structure that enhances absorption. It opens opportunities for more efficient, compact, and cost-effective solar technologies.
Key Benefits / Advantages:
✔ Enhanced absorption increases light capture across a range of angles
✔ Photonic crystal design improves efficiency without added bulk
✔ Scalable fabrication compatible with existing manufacturing processes
✔ Broad applicability across photovoltaic technologies
Applications:
• Solar panels and modules
• Building-integrated photovoltaics
• Portable solar devices
• Renewable energy systems
