This type of solar cell absorbs light not completely, because if it did virtually no sunlight to enter our home and have to live with the lights on all day. Thanks to technology , the new cell that absorbs near-infrared sunlight and has an ERA of 4%, which may seem low, but speaking to large scale and with the improvements to be implemented, will undoubtedly be an invention great for be used in medium and large buildings.
