Revolutionary Solar Cell Transmits Light, Generates Power for Smartphones & Windows
A Japanese research team has developed a revolutionary solar cell that transmits 80% of visible light and generates power at 420 picowatts per square centimetre. This breakthrough, led by Professor Masashi Kondo at Tohoku University, could transform energy generation on everyday devices like smartphones and windows.
The cell's power generation layer is a mere 1nm thick, made from a metal compound dichalcogenide. This thin film allows it to transmit a significant amount of light, setting it apart from traditional solar cells that absorb most light.
The cell generates about 420 picowatts of power on an area of 1cm, making it suitable for installation on various surfaces such as smart phones, glasses, windows, and other applications. With an outdoor service life of up to 10 years and a conversion efficiency of about 15%, it's designed for longevity.
Sekisui Chemical, a hybrid enterprise in Japan, is backing the technology. They plan to commercialize it by 2025, with initial verification starting in Osaka City in 2024. The company aims to achieve practicality within five years.
This innovative solar cell, developed by Professor Kondo and Sekisui Chemical, promises to revolutionize energy generation on small devices. Its ability to transmit light while generating power could lead to widespread integration in everyday technology, potentially reducing our reliance on traditional power sources.
