Scientists from South Korea’s UNIST have created transparent solar cells that can charge smartphones and power devices using sunlight. The team, led by Professor Kwanyong Seo, introduced a unique design called “All-Back Contact.” This design keeps the front of the solar cells clear, without any wires or cords, making them more efficient and visually appealing.
The researchers tested these solar cells using a 16 cm² module and found that they were able to charge a smartphone entirely from sunlight. This breakthrough shows the potential of using solar power for everyday devices, helping reduce the reliance on traditional electricity sources.
These transparent solar cells have a wide range of possible applications, including in buildings, cars, and small devices. By making the cells transparent, they could be installed on windows or other surfaces without blocking light or changing the appearance of the structure.
The team at UNIST is now working on further improving the technology to make it suitable for commercial use. They believe that this eco-friendly invention could be used in many different industries and help contribute to a greener future by providing clean energy through sunlight. The development of these solar cells marks an exciting step toward using renewable energy more efficiently in our daily lives.
