Taiwan's research and development of solar organic light-emitting diodes attracts worldwide attention

According to the Central News Agency, Zhou Zhuohui, a professor of materials at Tsinghua University in Taiwan, said that he successfully developed the first solar-emitting organic light-emitting diode (OLED) in human history.

Zhou Zhuohui said that the research team's innovative methods and the production of solar-like components were approved for publication in the internationally renowned Journal of Applied Physics Newsletter; this invention will rewrite the history of human lighting for 200 years. Like the natural light color and color temperature of the sun.

Zhou Zhuohui said that this invention is the first time that humans have discovered a simple OLED with a structural structure that emits a light color that is very close to sunlight. Through a simple voltage change, a color temperature change of 2300 to 8200K (absolute temperature) can be obtained, covering 3000K at sunrise and 2500K at sunset also cover 5500K at noon on a sunny day, 6500K at noon on a cloudy day, and even 8000K on a blue sky in northern Europe.

He said that this discovery will rewrite the history of human lighting. It will be of great help to winter or long-term sun-free areas, such as Northern Europe, especially to recognize that local people suffer from severe depression and even suicide because they do not receive sunlight for a long time. I can feel the importance of this invention. According to the observations of internationally renowned journals, this invention will attract attention in the fields of physics, engineering, lighting, photography, and psychology.

He pointed out that OLED is a flat light, unlike traditional light bulbs or modern LEDs, which are just point light sources, and fluorescent lamps are only line light sources. In addition, OLEDs are also beautiful cold light, unlike bulbs that generate heat, burn, and waste cold air power; It can be made on plastic sheets, so that the illumination source can be posted like a wallpaper, and the natural light source will make OLED the best choice for the ultimate high quality lighting target in the future.

Zhou Zhuohui pointed out that the huge output value and prospects of OLEDs deserve to be worked hard and pay attention.
