High voltage to charge 3.2V battery cells
If I turn the voltage up on my charger to say 4 or 5V, the current goes up to 10A (which would take less time to charge up - of course I would monitor it until the cell reaches say 3.4-ish then drop my charger to 3.5V so as not to miss my upper target). All is fine until you blink and the cell is at 5 volts. takes forever to get 3.4 volts

Voltage drop under load
The voltage you see when a battery is under (heavy) load has no relation to the voltage vs state of charge curve. In the latter, the voltage refers to the "resting" voltage - no charging or discharging for a few hours. It is perfectly normal/acceptable for the battery voltage to sag by 0.5 to 0.7 V under heavy load.

You should use a buck-boost converter that outputs 5V directly, with no additional regulators needed. Or, if you want a simple solution, just put a few 5V2 Zener diodes in parallel to shunt the high voltage from the solar cell. Make sure you got enough of them to dissipate about 40% of the solar cell''s maximum output power.

noob question about buck-converter | DIY Solar Power Forum
If you translate that down to 5V you get about 3A, there are losses of course so less than 3A peak and your buck converter won''t try to keep the panel at what ever it''s optimal voltage so things will flit around a bit. the solar cell voltage will be higher than the peak power voltage, assuming there is enough light hitting it. At some point
6 FAQs about [Solar cell voltage is less than 5v]
How many volts does a solar panel produce?
Open circuit 20.88V voltage is the voltage that comes directly from the 36-cell solar panel. When we are asking how many volts do solar panels produce, we usually have this voltage in mind. For maximum power voltage (Vmp), you can read a good explanation of what it is on the PV Education website.
Are high voltage solar panels better than low voltage?
High voltage solar panels are more efficient than low voltage panels and require less space to deploy, which reduces the cost of materials and labor for mounting them on a roof or ground mount. High voltage panels require thinner copper wire to connect the array, the charge controller, and the battery bank.
How to calculate solar panel output voltage?
If you know the number of PV cells in a solar panel, you can, by using 0.58V per PV cell voltage, calculate the total solar panel output voltage for a 36-cell panel, for example. You only need to sum up all the voltages of the individual photovoltaic cells (since they are wired in series, instead of wires in parallel). Here is this calculation:
What determines solar panel output voltage?
The output voltage of a solar panel is determined by the number of solar cells wired together into a single panel. High voltage solar panels have more cells connected and are more efficient than low voltage panels. They also require less space to deploy, reducing the cost of materials and labor for mounting on a roof or ground mount.
What is a typical open circuit voltage of a solar panel?
To be more accurate, a typical open circuit voltage of a solar cell is 0.58 volts (at 77°F or 25°C). All the PV cells in all solar panels have the same 0.58V voltage. Because we connect them in series, the total output voltage is the sum of the voltages of individual PV cells. Within the solar panel, the PV cells are wired in series.
How many volts is a 36 cell solar panel?
36-Cell Solar Panel Output Voltage = 36 × 0.58V = 20.88V What is especially confusing, however, is that this 36-cell solar panel will usually have a nominal voltage rating of 12V. Despite the output voltage being 18.56 volts, we still consider this a 12-volt solar panel.
