Solar cell receiving all wave band of solar spectrum

Disclosed is a solar cell receiving all wave band of solar spectrum, which utilizes cobalt doping tin dioxide as the material of a negative semiconductor layer so that it's capable of using a spraying technique and a hot-pressing process to manufacture the solar cell and solving the high cost problem caused by the manufacturing process of the prior art being obliged to proceed in a vacuum environment or a furnace tube environment; furthermore, the negative cobalt doping layer of the present invention going with a positive semiconductor layer of cuprous oxide can also achieve the capability of receiving all solar spectrum. Besides, the negative cobalt doping layer of the present invention can adapt to a low temperature process of manufacturing a solar cell so that plastic material can be an option for the substrate of a solar cell, which consequently solves the manufacturing problem of the prior art caused by the high temperature process being obliged to use a high temperature tolerable substrate such as glass
