Abstract The fabrication of kesterite Cu 2 ZnSn(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 carbon‐free clean energy production. However, reported power conversion efficiency approximately 10 % electrodeposited CZTSSe lower compared alternative methods like sputtering spin‐coating, mainly attributed phase inhomogeneity rough morphology generated during ED process. Ensuring microscopic macroscopic uniformity films crucial improvement film quality device performances. In this review, strategies address these challenges including intrinsic control such as mode, pH, concentration metal ions, complexing agents, well extrinsic approaches doping, substitution elements, introduction interfacial layers. addition, prospects electrochemically deposited were presented, focusing on promising applications in tandem, flexible, water‐splitting devices. Finally, review will provide technical insights into process preparing cells, outlining perspective future development highly efficient thin cells.

Advanced Science, Год журнала: 2023, Номер 11(6)

Опубликована: Дек. 6, 2023

Abstract Ion doping is an effective strategy for achieving high‐performance flexible Cu 2 ZnSn(S,Se) 4 (CZTSSe) solar cells by defect regulations. Here, a Li&Na co‐doped applied to synergistically regulate defects in CZTSSe bulks. The quality absorbers with the uniformly distributed Li and Na elements are obtained using solution method, where acetates (LiAc NaAc) as additives. concentration of harmful Zn anti‐site decreased 8.13% after incorporation, that benign increased 36.91% incorporation. Synergistic co‐doping enhances carrier reduces interfacial one order magnitude. As result, cell achieves power conversion efficiency ( PCE ) 10.53% certified 10.12%. Because high homogeneous property, device fabricated large area (2.38 cm obtains 9.41% . investigation provides new perspective efficient cells.

Interfacial Bridge Bonding Enables High‐Efficiency Sb₂(S,Se)₃ Solar Cells with Record Fill Factor Exceeding 73%

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 27, 2025

Abstract For solar cells, interfacial chemical coordination, carrier transport, and energy alignment play critical roles in transport determine the final conversion efficiency. As an emerging technology, high‐efficiency Sb 2 (S,Se) 3 cells typically utilize cadmium sulfide (CdS) as electron layer. However, poor electrical contact between F‐doped SnO (FTO) substrate CdS presents a significant challenge to improving device performance. Here, ultrathin layer is introduced, fabricated via bath deposition, FTO address coordination problem. The non‐invasive depth analysis based on synchrotron radiation X‐ray photoelectron spectroscopy shows that this engineering approach facilitates formation of S‐Sn bonding at FTO/CdS interface, which cannot be achieved conventional inert surface. Additionally, existence reduces sulfur vacancy defect (V S ) films, enhancing both conductivity crystallinity. Therefore, cell demonstrates significantly enhanced separation Ultimately, achieve record fill factor exceeding 73%, with championefficiency 10.58%. This study effective strategy enhance charge properties for high‐performance cells.
