In desperate motive of a more efficient structure for their tiny solar cells , engineers grow to the humankind ’s foremost expert on nanotechnology : Mother Nature . The corneas of flies are the thoroughgoing nanostructures for the next multiplication of solar cell .
This finical theatre of engineering is known as biomimetics , which is passably much exactly what it sounds like : build structures that mimic their biologic similitude . A lot of biomimetic inquiry focuses on insects , but it is n’t always possible to transform an efficient biological bodily structure into an easy replicable artificial structure .
As Penn State professor and extend researcher Akhlesh Lakhtakia explains :
“ Bioreplication begin about 2001 or 2002 . All the technique currently available are not conducive to mass replications . In many cause you could make as many replication as you need , but you want an insect for each reverberation . This is not good for industrial determination . ”
Oftentimes , the perfect biomimetic social system will have just the right mix of big and small features . The corneas of the blowfly species proved idealistic :
“ We needed an object tumid enough to manipulate that still had nanoscale features . These eyes are staring for making solar cells because they would collect more sunshine from a with child arena rather than just light that falls straight off on a matted Earth’s surface . ”
Blowfly eyes are hemispherical , chemical compound social organization , with each hemisphere covered with individual hexagonal eye . As a whole , these optic are macroscale structure , but their someone sport stride into nanoscale district . That ’s the perfect compounding to both duplicate the structure using a mold and then increase the size of it of the stilted duplicate without sacrifice any of the helpful single detail .
That last bit is perfectly crucial if these blowfly cornea are going to pave the way to a useful technology . An early paper by Lakhtakia and his colleaguescame up with a designfor new crystalline lens using fly eyes that would improve solar cell function . They have been able to put together arrays of nine blowfly optic to create replicable templates , although their next template will feature an array of 30 cornea . Once they have enough templates , they can tile them together and originate creating much larger open , which can then be used to build these fly front - designed solar cells .
