Improving the effectiveness of a photovoltaic system by water impinging jet on the surface of photovoltaic cells

셀 표면의 충돌제트를 이용한 태양광발전 시스템 효율향상에 관한 연구

This study is focused on the improving effectiveness of a photovoltaic system. The characteristic of crystalline silicon solar cells, that 0.5% reduction in generating power is occurred by increasing temperature $1^{\circ}C$ of module. Typically, average solar generating power is higher spring and fall than summer. Degradation phenomena shall shorten the life of the module when the temperature of modules is $70^{\circ}C$. Decreasing temperature 40degree of the module and increasing the solar power 20% was presented using the water impinging jet method on the surface of photovoltaic cells. It is shown that Impinging jet have an effected on heat and deliver effective substance from the area in which the injection is effective.
