Eight Solar
Cell Lithium Ion Battery Charger -
A single lithium
ion battery cell needs 4.2v from a current source to insure it is
fully charged. A solar panel with just enough individual cells
wired in series to produce the needed voltage would be more efficient
than one with more cells for a given surface area. If you divide
4.2 by eight you come up with a figure of 0.525 volts....[Circuit

Eight Solar
Cell Lithium Ion Battery Charger Version 2 -
Jim Wilber looked at
my design for a battery charger and sent me some suggested changes.
He suggested using the LTC4412 ideal diode IC to switch off the
current path from the solar cell to the battery in darkness. He also
noted that the 2.5v regulator from Seiko I had selected was no longer
in production and suggested using the shunt reference. I think his
suggestions made a lot of sense. In my design, in dark conditions,
the first MOSFET Q1 would not turn off until well after the point
where the solar panel no longer produces current, allowing some
leakage current to flow from the battery into the solar panel......[Designed
