Secrets of fluorescent microalgae could lead to super-efficient solar cells
Posted on 10 May 2019
Tiny light-emitting microalgae, found in the ocean, could hold the secret to the next generation of organic solar cells, according to new research carried out at the Universities of Birmingham and Utrecht.
Microalgae are probably the oldest surviving living organisms on the planet. They have evolved over billions of years to possess light harvesting systems that are up to 95 per cent efficient. This enables them to survive in the most extreme environments, and adapt to changes our world has seen over this time-span.
The team made use of some of the advanced methods of a technique called mass spectrometry, which enabled them to characterize individual components of the algae light-harvesting system. This approach enabled them to reveal details of distinct modules of the system that have never been seen before. This fine detail will help scientists understand why microalgae are so efficient at light harvesting.
The next step for the team will be to study in more detail how energy is transferred through these light-harvesting systems and pinpoint why the modules they have identified are so efficient. With most solar panels on the UK homes operating at 10-20 per cent efficiency, increasing this efficiency to 95 per cent will dramatically increase the use of solar power technology and in doing so help protect the environment, adds Dr Leney.
