- •
12 % efficiency was obtained for 11 µm thick, liquid-phase crystalized Si on glass.
- •
Using KOH texturing and anti-reflection foil, a JSC of 28.9 mA/cm2 was achieved.
- •
Current density losses were characterized using LBIC, optics, EQE and simulations.
- •
Main loss factors were direct reflection, the absorber contact and recombination.
- •
Max. light trapping potential was almost reached, using a backside pyramid texture.
