Subject: [alt-beam] Silicon Cell report
I had five bucks lyin' around and really wanted to check out these solar
cells, hey if your only buyin a couple its cheaper to do it without shipping
charges. These cells are 2 x 4 cm and the width of a sheet of paper, they're
really really thin! the cells have a positive strip which runs along the
bottom edge of each side, front negative, back positive. the output is .45v
at .3A not mA. here is where the fun is, lets make the cell just enough to
operete a 1381J or L, but with still enough current to make it worthy of
being used in place of a sunceram (which still rock the house). which brings
me to my question, is amperage directly related to surface area, y=kx. I
would believe so, but don't want to try it out for myself. as for voltage,
the voltage of the cell, when split up, would multiply by the number of
segments where s is #segments and .45 is votage meaning VDC = .45s? see what
i'm sayin, i put it algebraiclly for all you left brain people whomever that
may be. anyways, back to the usage of the cell, these would make cool cells
for a pvore, but what needs to be done is have a mount for it, something flat
so the cell won't break. They come in one of those nifty little plastic
cases, which makes me think ROBOT IDEA! if all my above asumtions are
correct, break the cell into 6 segments, hook 'em in a series, mount them to
the inside of the clear plastic container, mount the circuitry on the inside,
put the large cap on the outsid and mount motors on the outside. sorry for
being lengthy but i thought i'd give you the whole story.
