And, if this is perfected, drones we become able to stay airborne for long periods of time. The likely result will be a disaster for privacy (with government drones aloft in continuous surveillance).

Team creates functional ultrathin solar cells

A team of researchers with Johannes Kepler University Linz in Austria has developed an ultrathin solar cell for use in lightweight and flexible applications. In their paper published in the journal Nature Materials, the group describes how they created their solar cells and then tested them with miniature aircraft.

For engineers working with solar cells, two major goals are increasing the amount of electricity that can be harvested from a single cell, and making cells thinner and lighter while still producing the same amount or even more electricity as thicker cells. In this new effort, the research team has found a way to produce a solar cell that is just three micrometers thick, yet is still 12 percent efficient.

To create thinner cells, scientists have turned to new materials, one of which is organolead halide perovskites. They are direct band semiconductors and thus absorb light more efficiently than…
