Review of studies about direct absorption solarcollectors

Renewable energy such as solar energy can provide our energy requirements. One of the best sourcesof renewable energy is solar energy with minimal environmental impact. From last decades, solarenergy has attracted the attention of scientists to great deal. Solar radiation is converted to usefulenergy using solar collectors. One of the collectors presented recently is direct absorption solarcollector. Direct absorption solar collectors have higher efficiency than to conventional flat plate solarcollectors using nanofluids as the working fluid. In this paper, we reviewed the studies done aboutdirect absorption solar collectors
