For 3.5V(at)350mA you will need 7 cells of ca. 35mm x 55mm .. and this is assuming that you are working close to midday fully exposed to the Sun ..
These 7 cells you can call a solar panel ..

Sizes against mA you can find here:

Usually we buy panels, ... yes.. the whole panel will be exposed to sun.

I wanted to know if any other cell is preferred over lithium cell in the cellular phone? And if not, what are the advantages of lithium over other cell. Please help.
