Phosphor-contained solar cell and method thereof

[0032]In summary, the major object of this invention is to provide a solar cell having a photoelectric conversion layer and a phosphor layer, wherein the phosphor layer comprising the up conversion phosphor or the down conversion phosphor.

[0033]Generally speaking, the general formula of the up conversion phosphor is X2Mo2O9:X or X2Mo2O9:X,X, wherein the X represents anyone of rare earth metal, such as La, Gd, etc. Moreover, the up conversion phosphor is doped with one or two kind of rear earth metal.

[0034]The general formula of the down conversion phosphor is JQX(PO4)2:X3+ or JQX(PO4)2:X2+,X2+, wherein J represents lithium, sodium or potassium, Q represents anyone of alkaline earth metal such as Mg, Ca, Sr, Ba. The definition of X is the same as previous. Beside, the down conversion phosphor is doped with one or two kind of rear earth metal.

[0035]To fully understand the purpose, feature and function of this invention, this invention is described as below by utilizing the preferred embo
