1. 1. Characterization of combinatorial Cu2ZnSnS4 thin films

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Joakim Adolfsson; [2018]
   Keywords : Photovoltaics; Kesterite; Material science; Raman; Photoluminescence;

   Abstract : The kesterite Cu2ZnSnS4 (CZTS) is considered as a possible absorber layer in future photovoltaic (PV) applications. The abundance of its constituent elements along with the material being non-toxic and having a direct band gap of around 1.5 eV make it an attractive material for solar cell applications. So far, cells with an efficiency of 12. READ MORE

3. 2. Evaluation of Cu2ZnSnS4 Absorber Films Sputtered from a Single, Quaternary Target

   University essay from Institutionen för kemi - Ångström

   Author : Liv Carlhamn Rasmussen; [2013]
   Keywords : Cu2ZnSnS4; CZTS; kesterite; sputtering; compound; quaternary;

   Abstract : Cu2ZnSnS4 (CZTS) is a promising absorber material for thin-film solar cells since it contains no rare or toxic elements, has a high absorption coefficient and a near ideal bandgap energy. It does, however, present some challenges due to the limited single-phase region of the desired kesterite phase and its instability towards decomposition. READ MORE

4. 3. Experimental study of Cu2ZnSnS4 thin films for solar cells

   University essay from Fasta tillståndets elektronik

   Author : Hendrik Flammersberger; [2010]
   Keywords : ;

   Abstract : Cu2ZnSnS4 (CZTS) is a semiconductor with a direct band gap of about 1,5 eV and anabsorption coefficient of 10^4 cm^-1, and is for this reason a potential thin film solarcell material. Demonstrated efficiencies of up to 6,8% as well as use of cheap andabundant elements make CZTS a promising alternative to current solar cells. READ MORE
