These flexible CIGS solar cells are lighter, weigh 65% less than conventional solar panels and say they can generate 10% more energy, their semiconductor layers are thinner, and they don’t use a substrate. glass.

The next generation of solar cells appear to be much lighter, more flexible, and more customizable. CIGS (Copper Indium Gallium Selenide) thin film solar technology could offer a host of advantages, such as much lighter weight, easier installation and higher power output, especially for buildings and vehicles.


Sunflare CEO Len Gao said that “its panels can be attached to any surface with just a special double-sided tape” and are flexible enough to conform to the curves of any surface, which could allow more in the articles of daily use will integrate them. The company claims to have “cracked the code” for manufacturing high-quality CIGS cells with its patented Capture4 process, which would allow mass production of its sol2 solar cells at a competitive price.


Sunflare’s solar cells are based on a stainless steel substrate, in a process they claim to use only 50% of the energy used to make conventional silicon solar panels, they require much less water and less toxic chemicals. to make a thin film of semiconductor materials. The result is that solar panels weigh 65% less than conventional panels, don’t require a rack for installation, and because of their superior low-light efficiency, they say they can produce 10% energy. more.

For the construction industry, Sunflare could be ideal for covering the “skin” of buildings, for roofs without having to worry about being overweight.


For the small consumer, these thin film solar panels could be applied to any consumer product, like backpacks, bags, golf carts, trailers, RVs, “solar awnings”, electric cars … and much more. This new technology can be used almost anywhere. Curves are no longer a problem.

According to company calculations, the Sunflare system could cut installation costs in half.

But can you buy and install it today? It’s not clear. According to the company, it completed its first successful production in 2015 and is expected to begin full-scale manufacturing shortly, but as of yet, there are no details on availability and pricing on its official website.
