Solar thermal utilization——An overview

Solar energy is an ideal renewable energy source and its thermal utilization is one of its most important applications.We review the status of solar thermal utilization,including:(1) developed technologies which are already widely used all over the world,such as solar assisted water heaters,solar cookers,solar heated buildings and so on;(2) advanced technologies which are still in the development or laboratory stage and could have more innovative applications,including thermal power generation,refrigeration,hydrogen production,desalination,and chimneys;(3) major problems which need to be resolved for advanced utilization of solar thermal energy.
