This pigment is used extensively in plastics and other applications for its UV resistant properties where it acts as a UV absorber, efficiently transforming destructive UV light energy into heat..................................Another site says "It is also a major component of sun block to deter the absorption of ultraviolet (UV) rays from the sun, the concentration of which determines the product’s Sun Protection Factor, or SPF.... One site says UV absorber, the other site says deters the absorbtion. I don't know what to think, but I ordered it and I'll try it... I didn't see titanium oxide on the one I ordered from England

1. If you block only the UV from the panels, you may not reduce the amount of current produced much, at least not relative to the heat generated in the panel.
2. In a sunscreen, a UV absorber deters the absorption of that same UV by your skin, where it would be harmful. It would be even nicer if it just reflected the UV instead, but you take what you can get.
