  1. 1. A comparative study of ZnO i-layer deposited with ALD and PVD for CIGS solar cells

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Joel Johansson Byberg; [2019]
    Keywords : CIGS; ZnO; ZnMgO; solar cells; thin film; zinc oxide; window layer; ALD; PVD;
