Rochester Hills, Michigan Patent of the Year – 2024/2025
Utica Leaseco LLC has been awarded the 2024/2025 Patent of the Year for innovation in renewable energy technology. Their invention, detailed in U.S. Patent No. 11942566, titled ‘Thin-film semiconductor optoelectronic device with textured front and/or back surface prepared from etching’, introduces a new way to boost the performance of thin-film solar cells and similar devices.
The patent focuses on creating precise surface textures through etching to increase light absorption in optoelectronic devices. These microscopic textures trap light more effectively, allowing the device to convert more sunlight into energy. This breakthrough directly improves the efficiency of solar panels, displays, and sensors.
Unlike traditional flat surfaces, the textured layers created by this method are carefully controlled to reduce reflection and maximize internal light capture. This means more energy output without increasing the size or cost of the device. The technology is also compatible with flexible and lightweight materials, making it ideal for portable solar applications and next-generation electronics.
Utica Leaseco’s invention opens the door for more powerful and affordable green technologies. By enhancing how thin-film semiconductors harvest and use light, it supports cleaner energy solutions across industries. This patent reflects a meaningful step toward improving energy efficiency in everyday devices while reducing reliance on fossil fuels.
