“…Consequently, the transport of each element of CZTS within the coating is limited at low temperatures; thus, using sintering aids was necessary to promote mass transport. For CZTS (or CIGS) light-absorbing layers, Se or S vapor is often used as the sintering aid, which is known to induce the liquid phase-assisted transport of CZTS elements within the layer [ 25 , 26 ].…”

Despite the improved conversion efficiency of Cu2(ZnSn)Se4 (CZTSe) solar cells, their roll-to-roll fabrication nonetheless leads to low performance. The selenization time and temperature are typically considered major parameters for a powder-based CZTSe film; meanwhile, the importance of the densification during the roll-to-roll process is often overlooked. The densification process is related to the porosity of the light-absorbing layer, where high porosity lowers cell performance. In this study, we fabricated a dense CZTSe absorber layer as a method of controlling the compression of a powder precursor (Cu1.7(Zn1.2Sn1.0)S4.0 (CZTS)) during the roll-press process. The increased particle packing density of the CZTS layer was crucial in sintering the powder layer into a dense film and preventing severe selenization of the Mo back electrode. The pressed absorber layer of the CZTSe solar cell exhibited a more uniform chemical composition determined using dynamic secondary ion mass spectrometry (SIMS). Under the AM 1.5G illumination condition, the power conversion efficiency of the pressed solar cell was 6.82%, while the unpressed one was 4.90%.

“…A complexing agent holds significance in the electrodeposition process as it works to reduce the variation in reduction potentials among different metal ions and enhance the solubility of metal ions. Moreover, it aids in decreasing the grain size in the deposits, ultimately improving the homogeneity and surface roughness of the precursor film [22a,32] . To investigate the effects of complexing agents in the electrodeposition process, Mkawi et al .…”

“…The morphology of the CZTS thin film after annealing process is significantly improved in the CZTS thin film with trisodium citrate complexing agent (Figure 9b). Moreover, many other complexing agents including glutamic acid, glycine, potassium thiocyanate, sodium sulfate, and sodium thiocyanate have been explored in addition to sodium citrate, tartaric acid, and EDTA or in combination with them [22a,32,34] . Therefore, the proper addition of complexing agents in an electrolyte solution can effectively control the morphology by forming a homogenous and compact film.…”

The fabrication of kesterite Cu2ZnSn(S,Se)4 (CZTSSe) thin‐film solar cells using the electrochemical deposition (ED), which is valued for its industrial feasibility, offers a cost‐effective and environmentally friendly approach to the carbon‐free and clean energy production. However, the reported power conversion efficiency of approximately 10 % for electrodeposited CZTSSe thin‐film solar cells is lower compared to the alternative methods like sputtering and spin‐coating, which is mainly attributed to the phase inhomogeneity and the rough morphology generated during the ED process. Ensuring the microscopic and macroscopic uniformity of the electrodeposited films is crucial for the improvement of the film quality and the device performances. In this review, strategies to address these challenges including the intrinsic film control such as the deposition mode, pH, concentration of metal ions, and complexing agents, as well as the extrinsic approaches such as doping, substitution of metal elements, and the introduction of interfacial layers. In addition, the prospects for the electrochemically deposited CZTSSe solar cells were presented, focusing on the promising applications in tandem, flexible, and solar water‐splitting devices. Finally, this review will provide technical insights into the ED process for preparing CZTSSe solar cells, outlining a perspective for the future development of highly efficient CZTSSe thin film solar cells.

“…However, vacuum methods require an expensive and complex operation to fabricate solar cells, which has always been an impediment for commercialization. 11 On the other hand, solution-based approaches like nanocrystals (NCs) ink, 12,13 electro-deposition 14 and hydrazine-based ink 15 have been widely used to produce low-cost and large area TFSCs. The highest power conversion efficiency (12.6%) of CZTSSe TFSCs have been reported using a hydrazine-based approach 16 which is very harmful to researchers and the environment.…”
