Solar power and panels have been around for a long time, but it is only in recent years that the technology has been available to make thinner and more powerful solar panels that are cost effective too. One start up, has managed to raise $93 (£59) million in venture capital in order to perfect their thin solar panel design that they believe will produce high quality results at around half the current cost.
According to the Twin Creeks Technology website, this is what is so special about thinner solar panels;
A state-of-the-art silicon wafer today might measure 200 microns, or 200 millionths of a meter, thick. While incredibly thin, 90 percent of the material like silicon primarily serves to give the wafer structure. Only a thin surface layer of the wafer ultimately gets used for active functions like transmitting signals. Twin Creeks saves manufacturers money by drastically reducing the amount of silicon and other materials needed to produce wafers.
