Harnessing the power of the sun has been on the top of many scientists’ lists for quite some time.  It’s just hanging out up there, making everything warm, so it’s a seemingly endless supply of wireless energy.  The problem is, we haven’t been able to make them cheap, powerful, or light enough to make them economically feasible.  A team of researchers believes they solved one of those problems as they’ve revealed a solar cell so light that it can rest on a soap bubble without popping it.
