Understanding the Challenge

The pursuit of harnessing sunlight for energy production has long been hindered by the destructive effects of solar radiation on materials. Over time, exposure to sunlight causes the gradual degradation of solar systems, ultimately impacting their performance. However, nature has already provided a solution in the form of plants, which continuously break down and reassemble their light-capturing molecules. This inherent regenerative process keeps the structures that capture sunlight in a perpetually new state.

Biomimicry Meets Solar Technology

Inspired by nature's regenerative prowess, a team of researchers at MIT, led by Associate Professor Michael Strano, has achieved a significant breakthrough. They have developed a set of self-assembling molecules that can transform sunlight into electricity while possessing the remarkable ability to be repeatedly disassembled and reassembled simply by adding or removing a specific solution. Their findings, published in Nature Chemistry, offer a glimpse into the future of solar technology.

Imitating Nature: The Science Behind It

To mimic nature's regenerative process, the MIT team engineered synthetic molecules known as phospholipids. These molecules take the form of disks and serve as the structural foundation for other light-responsive molecules known as reaction centers. When exposed to light, these reaction centers release electrons. The entire system involves seven distinct compounds, including carbon nanotubes, phospholipids, and the proteins making up the reaction centers. These components spontaneously assemble into a light-harvesting structure that generates an electric current.

A Remarkable Self-Assembling System

What sets this innovation apart is the complexity of its self-assembling system. When a surfactant, similar in principle to the chemicals used in oil dispersion, is introduced to the solution, all seven components disband, forming a solution. However, upon removing the surfactant by pushing the solution through a membrane, the compounds spontaneously reassemble into a fully functional and rejuvenated photocell. The ability to break apart and reassemble is a remarkable feat, inspired by millions of years of evolution.
