What is the maximum temperature a concentrator solar cell can handle?
During assembly, the cells can be exposed to temperatures as high as 300 C for a few minutes. During operation, we suggest maintaining a temperature below 100C. Higher operating temperatures will reduce the cell efficiency and may jeopardize the lifetime of the cells in the field. Cell performance is a function of temperature. For every 10 C rise in cell temperature, the cell efficiency drops by about 0.5% absolute efficiency. That is, a 38% cell at 25 C will be a 37% cell at 45 C.
