This is a 5V Polycrystalline Solar Cell with PET laminated finish, to ensure it has a waterproof cell face and therefore is suitable for many applications.
Solar power cells make great introductions to solar power projects, suitable for things such as outside lights.
Rear-mounted solder pads with 20cm leads for easy attachment.
It provides a maximum current of 130mA, at a power of 0.65W, and does NOT include a blocking diode. In projects where this solar cell is used to charge batteries a blocking diode must be added to the circuit in order to prevent the batteries from discharging back into the cell when it gets dark.

Are the 5V solar cells fairly powerful enough for a basic solar panel messenger bag project to perhaps slow charge up a mobile?
To get the most out of a solar cell it needs to be angled towards the sun, then on a cloud free summers day it is possible to get the power out of the solar cell that matches the specification. If the cell is not directed at the sun or it is cloudy then you will only get a fraction of the power out of the cell, maybe only 10% of the full rating. It is also worth noting that whilst the cell in this case is rated at 5V that is a nominal 5V, if it is sunny it may well be a volt or so higher and if it is cloudy it might only reach half the target 5V if you have something hooked up to it.
To charge a mobile from the USB connector you would need a stable 5V supply and are likely to need at least an amp. Whilst you can trickle charge some cells such as NiMh batteries the LiPo batteries in mobiles need to be charged in a different way using constant current and constant voltage phases. The phone deals with this but it doesn’t work if there isn’t enough current. As mad as it might sound the easiest way to get around this would be to trickle charge 4 AA NiMh which have 1.2V across them slowly and then once charged use that to rapid charge the phone. The alternative is a big and expensive solar cell with a 5V regulator circuit.
