High Performance with Maximum Efficiencies

At Concentrix Solar´s FLATCON^® power plants, special III-V based triple-junction solar cells (GaInP/GaInAs/Ge) are used. Here three different types of solar cells are stacked on top of one another. Each cell type is sensitized to convert a certain spectral region of the solar radiation: short wave, medium wave and the infrared range.

The energy yield of these high efficiency cells is enormous. Efficiencies of 38% have been achieved. This is almost double the efficiency of conventional solar cells.

For a long time, triple-junction solar cells were used only for space applications. In comparison to conventional solar cells, such cells are expensive to manufacture. By focusing the sunlight using FLATCON^® modules, it was possible for Concentrix Solar to minimize the amount of semiconductor material needed down to a small fraction.
