how do i make my own solar cell? Answered


there is one long way, transistor using metal cap can be used as solar cell. spatially germanium based, cut top and emitor , when exposed to sun potential develop . connecting in series as req. can be used as solar cell.

No way, for practical power.

Have a look at this question that was asked and answered earlier today, or Google "diy solar cell" for more info.  There is not much on making your own cell because the ways to do a diy cell are very limited.
