Using nanotechnology, Professor Stephen Chou increased the effectiveness of solar cells by 175% back in 2012. Now, Professor Chou has improved the LED. Besides making them last longer and more efficient, the professor has made LEDs five times clearer. The implication for smartphone users is tremendous. Currently, only 2% to 4% of the light generated by an LED is actually emitted by the diode. This makes the light dim and also helps give an LED short life since it is generating heat inside itself.Scientists have been able to raise the percentage of light generated by LEDs to 38%. In doing ...
