The only problem that occured so far is that I couldnt turn the kindle on after a while in full sunlight. After a couple of minutes to cool down it starts as usual.

The eink display and the battery each have temperature sensors. In the case of the eink, it adapts the eink waveform to the temperature, and it may have been too high for the firmware to draw to it. But more likely, the firmware decided that the battery was outside safe operating limits, and prevented operation until it cooled down.
It may help to have a fan blowing on the kindle while it is solar charging, but that would consume more electricity than using a USB charger.
Perhaps a thin insulating layer (like a mylar emergency blanket from a first-aid kit) may help keep heat from the solar cell from radiating into the kindle PCB. You could wrap the backside of the solar cell like they do with electronics installed in satellites.
