Shipping may be prohibitive elsewhere, but those in the US may be interested in these 3 volt, 40 ma solar cells for $3.75US from All Electronics:

Considering the current draw on many PICAXE projects, one cell could keep 2 AA NiCD/NiMH cells charged with just a few hours of sunlight.
Oh yes, cheaper in quantity - if you're interested in 100 at $3.25 each ;-)
