Predicting Solar Cell Performance from Terahertz and Microwave Spectroscopy

Hannes Hempel et al.

Summary: This article combines the expertise of fifteen laboratories to quantitatively model the current-voltage characteristics of photovoltaic materials, using (Cs,FA,MA)Pb(I,Br)(3) halide perovskite thin-film as a case study. The study examines the impact of measurement conditions, alternate interpretations, and experimental inter-laboratory variations. The results show that terahertz, microwave, and photoluminescence measurements can provide consistent information on the mobility and lifetime of charge carriers in the material, which is crucial for the efficiency of solar cells.

Self-doping behavior and cation disorder in MgSnN2

Dan Han et al.

Summary: This study investigates the phase stability, defect properties, and cation disorder of MgSnN2 and ZnSnN2 using first principles calculations. It is found that MgSnN2 can form in two different phases, while ZnSnN2 only crystallizes in one phase. MgSnN2 exhibits self-doped n-type conductivity, and the defect Sn-Mg is the primary source of free electrons. Cation disorder in MgSnN2 induces a reduction in the band gap due to violation of the octet rule.

Marin Rusu et al.

Summary: The study shows that KF-PDT and RbF-PDT have a significant impact on the electronic properties of CIGSe thin films and the CdS/CIGSe interface, with the CIGSe surface band gap depending on the type of postdeposition treatment and a thin layer with a graded band gap found at the CdS/CIGSe interface. K and Rb act as compensating acceptors in the CdS layer.
