dc.description.abstract | The introduction of the alkaline-earth element Magnesium (Mg) into Cu 2 ZnSn(S,Se) 4 (CTZSSe) is explored in view of potential photovoltaic applications. Cu 2 Zn 1-x Mg x Sn(S,Se) 4 absorber layers with variable Mg content x = 0...1 are deposited using the solution approach with dimethyl sulfoxide solvent followed by annealing in selenium atmosphere. For heavy Mg alloying with x = 0.55...1 the phase separation into Cu 2 SnSe 3 , MgSe 2 , MgSe and SnSe 2 occurs in agreement with literature predictions. A lower Mg content of x = 0.04 results in the kesterite phase as confirmed by XRD and Raman spectroscopy. A photoluminescence maximum is red-shifted by 0.02 eV as compared to the band-gap and a carrier concentration N CV of 1 × 10 16 cm -3 is measured for a Mg-containing kesterite solar cell device. Raman spectroscopy indicates that structural defects can be reduced in Mg-containing absorbers as compared to the Mg-free reference samples, however the best device efficiency of 7.2% for a Mg-containing cell measured in this study is lower than those frequently reported for the conventional Na doping | en_US |
