Solar chillers could be accomplished by using one of the following refrigeration systems: vapor compression, adsorption refrigeration , and thermoelectric refrigeration systems.
Solar-driven thermoelectric technologies have two types: the solar-driven thermoelectric refrigeration and the solar-driven thermoelectric power generation .
Since the heat transfer coefficient during evaporation is considerably higher than that of sensible heat transfer alone, the COP of the thermoelectric refrigeration system is expected to improve.
A portable beverage container 10.8x7.9x7 in (27x20x18 cm) inside space volume was retrofitted into a thermoelectric refrigeration system.
Increase of COP in the thermoelectric refrigeration by the optimization of heat dissipation.

It turns out that the optimal compositions for thermoelectric refrigeration are normally [Bi.sub.0.5][Sb.sub.1.5][Te.sub.3] and [Bi.sub.2][Te.sub.2.7][Se.sub.0.3] for the p-type and n-type, respectively.
Lead telluride (PbTe) is typically used for thermoelectric refrigeration or cooling at higher temperatures, around 500-800 K, than [Bi.sub.2][Te.sub.3] (28), (29), (33-36).
