A small refridgerating device powered by a photovoltaic cell. It
wouldn't have to be a great refridgerator that would keep a
drink icy-cold or keep perishables safe to eat, but just enough
of a fridge to keep a bottle of water not so hot that it's
unpleasant to drink. Won't work when it's not
sunny outside,
but then it wouldn't need to work.

A refrigerator is a heat pump. You need to move the heat from one place to another. Where would the heat go? Would you really want to pump it into your car on a hot day? |

Solar powered peltier device attached to side of beverage holder. Been done, but I can't find the link at the moment. |

The amount of heat pumped out of a small 'fridge (maybe 2,000 cm^3) is going to be insignificant when pumped into the interior of a car that would be at least 1,000,000,000 cm^3. |

It would be like the amount of heat your home 'fridge pumps into your home. |

That's an awfully big car--about 500 times the size of mine. |

Converting solar energy into electrical energy to power a phase change device, is the long way around. You need a phase change that can be powered by a thermal process, solar concentrator (or in the absence of sunlight, yes it does occur) another thermal process. The "icy-ball" of yore achieves these objectives. |
