“…The development of earth-abundant chalcogenide materials has various applications such as spectroscopy, optoelectronics, and photovoltaics. − Instead of conventionally expensive and toxic Cd- and Pb-based chalcogenide compounds, recent studies on copper-based chalcogenides, such as Cu 2 X(X = Zn, Fe, Co, Ni, Mn)SnS 4 (i.e., CXTS), further draw extensive attention owing to their excellent optoelectronic properties, including p-type conductivity and direct band gaps of ∼1.2–1.5 eV. , Moreover, a high absorption coefficient in the visible range − makes them attractive as p-type photoabsorbing layers for optoelectronic devices. − Among various CXTS compounds, Cu 2 NiSnS 4 (CNTS) was found to exhibit an optical absorption coefficient of ∼10 6 cm –1 and a very low conduction band offset (−0.12 eV). ,,,− Furthermore, the optical properties of chalcogenide nanocrystals are significantly dependent on the chemical composition, crystal structure, particle size, and surface morphology, which could be controlled by synthesis methods. The proper amount of metal salt precursors together with chalcogen sources starts nucleation in a solution with a relatively low temperature, which makes their stabilization in nanocrystal (NC) form hugely amenable.…”

The incorporation of plasmonic metal nanostructures into semiconducting chalcogenides in the form of core−shell structures provides a promising approach to enhancing the performance of photodetectors. In this study, we combined Au nanoparticles with newly developed copper-based chalcogenides Cu 2 NiSnS 4 (Au/CNTS) to achieve an ultrahigh optoelectronic response in the visible regime. The high-quality Au/CNTS core− shell nanocrystals (NCs) were synthesized by developing a unique colloidal hot-injection method, which allowed for excellent control over sizes, shapes, and elemental compositions. The as-synthesized Au/CNTS hybrid core−shell NCs exhibited enhanced optical absorption, carrier extraction efficiency, and improved photosensing performance owing to the plasmonic-induced resonance energy transfer effect of the Au core. This effect led to a significant increase in the carrier density of the Au/CNTS NCs, resulting in a measured responsivity of 1.2 × 10 3 AW −1 , a specific detectivity of 6.2 × 10 11 Jones, and an external quantum efficiency of 3.8 × 10 5 % at an incident power density of 318.5 μW cm −2 . These results enlighten a new era in the development of plasmonic core−shell nanostructure-based visible photodetectors.

“…progress in CZTSSe photovoltaics, the current efficiency of CZTSSe solar cell is far below its theory limit [4,5]. The main factor limiting the performances of CZTSSe solar cells is the low open-circuit voltage (V OC ), which is caused by the serious carrier recombination via deep-level defects and/or interfacial defects [6][7][8][9][10][11][12][13].…”

In this paper, the open-circuit voltages (VOC) of Cu2ZnSn(S,Se)4 (CZTSSe) solar cells were improved by soaking the CZTSSe films in Cd/NH3 solutions before the deposition of buffer layers. The effects of the Cd/NH3 soaking on the properties of CZTSSe films and solar cells were investigated in depth. We found the Cd/NH3 soaking can promote the downward band bending of the CZTSSe layer at the surface region. Except that, the Cd/NH3 soaking can eliminate the deep level acceptor in CZTSSe and decrease the density of the defects at the absorber/buffer interface. These effects can significantly reduce the carrier recombination in the depletion region of CZTSSe solar cells. As the results, the VOC of CZTSSe solar cells were increased from ~460mV to ~480mV, the efficiency of the best CZTSSe solar cell was increased from 10.2% to 11.6% by the Cd/NH3 soaking process.

Renewable energy is crucial for sustainable future, and Cu2ZnSnS4 (CZTS) based solar cells shine as a beacon of hope. CZTS, composed of abundant, low‐cost, and non‐toxic elements, shares similarities with Cu(In,Ga)Se2 (CIGS). However, despite its promise and appealing properties for solar cells, CZTS‐based solar cells faces performance challenges owing to inherent issues with CZTS material, and conventional substrate structure complexities. This review critically examines these roadblocks, explores ongoing efforts and breakthroughs, providing insight into the evolving landscape of CZTS‐based solar cells research. Furthermore, as an optimistic turn in the field, the review first highlights the crucial need to transition to a superstrate structure for CZTS‐based single junction devices, and summarizes the substantial progress made in this direction. Subsequently, dive into the discussion about the fascinating realm of CZTS‐based tandem devices, providing an overview of the existing literature as well as outlining the possible potential strategies for enhancing the efficiency of such devices. Finally, the review provides a useful outlook that outlines the priorities for future research and suggesting where efforts should concentrate to shape the future of CZTS‐based solar cells.
