aNewDomain.net — Got CIGS? No, I’m not trying to bum a smoke, but I’m guessing you and I both will be getting some CIGS soon. Solar panels based on copper indium gallium selenide (CIGS) tech are lighter, more flexible and efficient than traditional silicon-based solar panels. And they’re hitting the market now. Here’s how CIGS solar panel tech works. Check out my EnerPlex video, below the fold.
Traditional solar cells comprise slices of crystalline silicon wafers mounted upon glass substrates. That’s why your typical solar panel is so bulky, heavy and fragile. They’re efficient, true, but only when aimed directly at the sun. But CIGS-based solar panels work on glass and plastic substrates. So CIGS panels are more flexible and less fragile.
Better still, unlike your typical crystalline silicon-based solar cells, CIGS devices are able to produce electricity even when there’s no direct sun. At CES 2014, I checked out the light, flexible CIGS solar panels from Ascent Solar Technologies. Its EnerPlex line of solar cells are hitting the market now in a variety of form factors. Here’s a closer look at how CIGS solar panels work and why you should care.
The CIGS-based panels in Ascent’s EnerPlex line show up in products from cell phone cases to huge 19-volt panels.
Take the four-panel Kickr IV. It produces five volts of electricity at up to six watts. That’s about the same capacity as you’d get from most USB wall outlet chargers. The whole thing folds up into a square pack three quarters of an inch thick. That’s about the size of a CD case. Total weight is just more than a half pound. Here’s my hands-on demo of the tech, below.
If the cigs mention at the top of this piece gave you a nicotine jones, be sure to check out my colleague Sandy Berger’s piece on electronic cigarettes.
