Solar Panels Have Volts but No Amps: Reasons and Fixes
current
It helps to understand that a solar cell is just an ordinary silicon diode (but awfully wide). It has the same curve. As it generates current, the voltage rises. As the voltage rises, the diode starts to conduct (above 0.4V), and …

Charging a 5V battery with a low voltage solar cell (0.5V)
Your reference to 5V makes me think you want to charge a regular "power bank" with this solar cell. This will not work, you need to charge the cell itself using a energy harvesting IC like u/triffid_hunter said. That means you either have to buy a battery bank with cells that you can swap out and use protected 18650 cells and build your solar charger for these …
Solar Cell Voltage-Current Characterization
Short circuit current, Isc, flows with zero external resistance (V= 0) and is the maximum current delivered by the solar cell at any illumination level. Similarly, the open circuit voltage, Voc, is the potential that develops across the terminals of the solar cell when the external load resistance is very large (Figure 3).
5V 10W Solar Panel
Each cell has a nominal voltage of 0.5V so we call this a "5V" panel They output a nominal 5V at a 1,670mA peak via a 3.5mm x 1.1mm DC jack connector. The panel is constructed with ETFE (Ethylene Tetrafluoroethylene), making it extremely durable and resistant to environmental elements, a superior upgrade to PET or laminate solar panel construction.

One cell drops to 2.5v while the others are still above 3.0 why?
The cell on low voltage charges up and balaces well with the others at the top end of the charge cycle. Then once the BMS has cut off due to the one cell low voltage (2.5), there''s the problem of re-starting the BMS. There are so many opinions on this and no "reset" button or advice from manufacturers.

Open-circuit potential of an electrochemical cell
For the solar cell you''re right. If the cell output is +0.5 volts then you''d have to apply -0.5 volts to stop the current flow if the voltage is applied across the cell itself. Two +0.5 sources in parallel would only give +0.5 volts output however. You''d have to arrange the solar cell and an additional +0.5 volts in series to get +1.0 volts output.

How Are Solar Cells Connected In A Solar Panel?
Under 25 C with AM1.5 light, each individual silicon solar cell has a voltage at the maximum power point of roughly 0.5V. Most modules have 36 solar cells in line to account for the projected reduction in PV module voltage due to temperature and the fact that a battery may require voltages of 15V or higher to charge.
