Webimpurities are compared, there is limited indication of interaction between impurities. For example, copper improves the efficiency of Ti- and V-doped cells, although the effect is small. Apparently, Cu diffuses to and combines with the second transition metal to reduce its electrical activity. Precipitated impurities have little or no effect ... WebApr 7, 2024 · Impurities can be easily removed if they are either much more soluble or much less soluble in the solvent than the compound of interest. Figure 3.9 shows the procedural sequence used to remove a " soluble impurity " from an impure soled, meaning an impurity that is embedded in the crystalline matrix, but would be completely soluble in the ...
