“…3,4 Perovskite is an appealing material for future generations. Methylammonium lead triiodide (CH 3 NH 3 PbI 3 , MAPI) is one of the most anticipated materials due to its superior properties such as tunable band gap, 5 low cost, high absorption coefficient, 6 low binding energy (20 to 32 meV), 7 solution processability, 8 long carrier diffusion length, 9 and strong electronic mobility. 10 Solution processability provides diversity in the choice of deposition techniques.…”

“…Owing to its durability, low toxicity, appropriate band gap, and good solar energy conversion efficiency, I-III-VI ternary metal sulfide semiconductors have received a lot of research attention thus far (Li et al, 2018;Zhang et al, 2021). Copper indium sulfide (CuInS 2 ) is a promising I-III-VI 2 ternary chalcopyrite material with a wide range of advantages for photocatalytic and photovoltaic applications (Yang et al, 2021b;Spera et al, 2022;Wang et al, 2022). Its conduction band is made up of In 5s orbitals, and its valence band is made up of S 3p orbitals, resulting in a small band-gap (1.53 eV for the bulk CuInS 2 ) (Chumha et al, 2020;Guo et al, 2021).…”

Despite significant scientific efforts in the field of water treatment, pollution of drinking water by toxic metal ions and synthetic organic compounds is becoming an increasing problem. The photocatalytic capabilities of CuInS2 nanoparticles were examined in this study for both the degradation of chloramphenicol (CAP) and the reduction of Cr(VI). CuInS2 nanoparticles were produced using a straightforward solvothermal approach and subsequently characterized by many analysis techniques. Simultaneous photocatalytic Cr(VI) reduction and CAP oxidation by the CuInS2 nanoparticles under visible-light demonstrated that lower pH and sufficient dissolved oxygen favored both Cr(VI) reduction and CAP oxidation. On the basis of active species quenching experiments, the possible photocatalytic mechanisms for Cr(VI) conversion with synchronous CAP degradation were proposed. Additionally, the CuInS2 retains a high rate of mixed pollutant removal after five runs. This work shows that organic contaminants and heavy metal ions can be treated concurrently by the visible-light-induced photocatalysis of CuInS2.

Intensity‐modulated photocurrent and photovoltage spectroscopy (IMPS/IMVS) are powerful tools in optoelectronics such as photoelectrochemistry and photovoltaics, as they demonstrate distinct charge dynamic processes at different frequencies. Unlike the material characterization techniques, IMPS/IMVS offer an approach for investigating the dynamic behavior of charge carriers and ions from the device perspective. This review examines IMPS/IMVS from both theories and experiments to understand the intricate charge dynamics in solar cells with various materials and structures. To accommodate different types of cells, four primary theoretical models including the rate constant model, drift‐diffusion model, equivalent circuit model, and distribution of relaxation times, are evaluated in detail. In the future, the incorporation of IMPS/IMVS with other time‐domain and frequency‐domain methods, along with imaging techniques, can significantly facilitate the characterization of charge dynamics with enhanced convenience, spatial dimensions, and accuracy.
