what is the chemical things that i can use for this system to increase the power produced from mW to W or KW. because what i think is to build bunch of these system in series to increase the power production but this way will not increase that much the power its may give me 1W that is enough just to charge my phone not enough for population used so what i think now is to add some chemical things to increase the power and its will be more effective and will produce much power.
