You need to put the panels in series, and then get a real solar charge controller. Basic buck and boost converters don''t know how to deal with the fluctuating voltage that comes from a solar panel. It might work with a buck converter and a very small load in full sunlight, but will fail when the load increased or a cloud goes overhead.
2. Use Rigid Solar Panels for Charging. You can use any type of solar panel for charging phones, but efficiency will vary. Rigid solar panels can charge devices twice as fast as thin film (flexible) solar panels. Thin film is cheaper and flexible, but the trade off is less efficient energy conversion.
