Photoelectrode that can harvest 85 percent of visible light

Posted by in categories: nanotechnology, solar power, sustainability

Scientists have developed a photoelectrode that can harvest 85 percent of visible light in a 30 nanometers-thin semiconductor layer between gold layers, converting light energy 11 times more efficiently than previous methods.

In the pursuit of realizing a sustainable society, there is an ever-increasing demand to develop revolutionary solar cells or artificial photosynthesis systems that utilize energy from the sun while using as few materials as possible.

The research team, led by Professor Hiroaki Misawa of the Research Institute for Electronic Science at Hokkaido University, has been aiming to develop a photoelectrode that can harvest visible light across a wide spectral range by using loaded on a semiconductor. But merely applying a layer of gold nanoparticles did not lead to a sufficient amount of , because they took in light with only a narrow spectral range.
