A research team at the Stuttgart University has achieved an efficiency record for laser-processed solar cells based on crystalline silicon. The researchers claim that the manufacturing process is fit for industrial volume production.
The
postgraduate research group led by Jürgen Köhler managed to produce
crystalline silicon solar cells with an efficiency of 19 per cent.
Hitherto, this technology was limited to 16 per cent.
In the normal solar cell manufacturing, the pn junction
is achieved in a high-temperature process in a diffusion furnace. The
Stuttgart research group however used a pulsed laser beam instead in
order to achieve the doping.
