  6. 25. Silicon surface passivation via ultra-thin SiO2, TiO2, and Al2O3 layers

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Anton Ek; [2019]
    Keywords : surface passivation; ALD; silicon; solar cell; SiO2; Al2O3; TiO2; stacks; characterization; optimization; RSM; temperature;

    Abstract : Energy traps at the silicon surface originating from discontinuities in the lattice is detrimental to the performance of solar cells. Acting as recombination centers, they offer a location where the charge carriers may easily return to their original energy band after excitation. READ MORE
