22.0% Efficient Laser Doped back Contact Solar Cells
2013
Energy Procedia
We present the first laser doped interdigitated back contacted solar cells with 22.0%. The cell area is 2 x 2 cm 2 , and contains the metallization of both busbars. The high flexibility and spatial resolution of our laser doping process enables local n-type and p-type doping with a precision below 30 μm and avoids any masking process.
