Most powerful micro-scale solar cell yet developed



WASHINGTON:
Scientists have developed a micro-scale biological solar cell that generates more power than any existing cell of its kind.

A microfluidic lab-on-a-chip system that generates its own power is essential for stand-alone, independent, self- sustainable point-of-care diagnostic devices to work in limited-resource and remote regions, said Professor Seokheun Choi, from Binghamton University in the US.

Miniaturised biological solar cells (micro-BSCs) can be the most suitable power source for those applications because the technique resembles the earth's natural ecosystem.

"Micro-BSCs can continuously generate electricity from microbial photosynthetic and respiratory activities over day- night cycles, offering a clean and renewable power source with self-sustaining potential," said Choi.

"However, the promise of this technology has not been translated into practical applications because of its relatively low power and current short lifetimes," he said.


Researchers created a microscale microfluidic biological solar cell that can attain high electrical power and long-term operational capability, which will provide a practical and sustainable power supply for lab-on-a-chip applications.

The bio-solar cell generated the highest power density for the longest time among any existing micro-scale bio-solar cells, according to a study published in the journal Lab on a Chip.

"The device will release biological photo-energy conversion technology from its restriction to conceptual research and advance its translational potential toward practical and sustainable power applications for point-of-care diagnostics to work independently and self-sustainably in limited-resource and remote regions," said Choi.
