Abstract
We present the first laser doped interdigitated back contacted solar cells with efficiency η = 22.0%. The cell area is 2 x 2 cm2, 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.
