Integrated microscale cooling for concentrator solar cells

摘要: The work presents a new solution proposal to the cooling of concentrator photovoltaic cells. In our concept microscale channels are integrated into back surface metallization, formed by electroplating copper around photoresist channel pattern. This approach has advantage that it no restrictions regarding solar cell material and technology. this we give description on process technology, perform mechanical simulations for feasibility approach, optimize geometry 20 × mm estimate performance structure at different operating conditions. We found, proposed would have calculated thermal resistance 0.26 K/W pressure drop 100 kPa. result in temperature raise less than 8 K case concentration level suns efficiency 25 %.
