In May of this year, researchers at the Nanyang Technological University in Singapore NTU Singapore revealed that they invented a new form of solar cell that is 10,000 times thinner than a strand of hair. Because it so thin, this new breed of solar panel — made out of a material with a crystalline structure known as perovskite — manages to be transparent and convert solar power to electricity. Admittedly, prior rival perovskite solar cells are more efficient, as are many commercially available...
