| Abstract | ||
| solar concentrator photovoltaic (cpv) is a potential solution to provide renewable energy at higher efficiency and less cost. the elevated temperature of the solar cells due to the accumulated heat leads to a decrease in the electricity generation efficiency of the solar cell. the current study aims to enhance the multijunction (mj) solar cell electrical conversion efficiency using a passive cooling technique. three configurations of mj solar cell modules as follows, a mj solar cell module without any heat sink, a mj solar cell module with flat plate fin and a mj solar cell module with straight fins attached to a flat plate base were simulated using acfd software. the effects of the ambient temperature have been studied under the constant solar concentration of 50 suns and wind speed of 1 m/s.the results showed that using a heat sink decreases the maximum solar cell temperature by 43.9% and 50.68% and consequently increases the solar cell efficiency by 4.08% and 4.68% in case of flat plate fin and straight fins attached to a flat plate base respectively compared to the solar cell without any heat sink. | ||
