A new technique for convection suppression in solar collectors is proposed. In this method the air in the gap between the absorber and the cover is stratified by the use of a heavy vapor. The amount of vapor required to achieve convection suppression is derived. The heavy vapor which diffuses from the absorber to the cover is recirculated using the principle of heat pipe. This technique is demonstrated by a simple experiment.
