In full summer sunlight, says Michael Strano of MIT's department of chemical engineering, "a leaf on a tree is recycling its proteins about every 45 minutes, even though you might think of it as a static photocell."More details at TG Daily.
Inspired by this, Strano created a set of self-assembling molecules that can turn sunlight into electricity; the molecules can be repeatedly broken down and then reassembled quickly, just by adding or removing an additional solution.
MIT develops self-healing solar cells

MIT researchers have created solar cells that repair themselves after damage from sunlight, similar to the way plants constantly break down their light-capturing molecules and reassemble them from scratch, to maintain optimal efficiency.
Conventional silicon-based photovoltaic cells have little degradation, but the new technology could come in handy for new types of solar cells that have very significant degradation.
