Decoupling of optoelectronic properties from morphological changes in sodium treated kesterite thin film solar cells [PDF]

, 2018
Sodium is typically used during the synthesis of kesterite thin films to enhance the performance of solar cells. As sodium tends to affect grain growth and morphology, it is difficult to analyse solely the electronic effects of sodium as dopant.

Defect Properties of Na and K in Cu2ZnSnS4 from Hybrid Functional Calculation

, 2017
In-growth or post-deposition treatment of $Cu_{2}ZnSnS_{4}$ (CZTS) absorber layer had led to improved photovoltaic efficiency, however, the underlying physical mechanism of such improvements are less studied. In this study, the thermodynamics of Na and K

Effect of the Order-Disorder Transition on the Seebeck Coefficient of Nanostructured Thermoelectric Cu₂ZnSnS₄

Nanomaterials, 2019
Bulk samples of kesterite (Cu2ZnSnS4, CZTS) were produced by cold-pressing and sintering of CZTS powders obtained via reactive ball-milling. An increase in the Seebeck coefficient of more than 100 μV/K, almost doubling the expected value, is noticed

Emerging Roles of Inorganic and Copper Chalcogenide‐Based Hole Transport Materials in Perovskite Solar Cells

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
In a decade ~7 times, enhanced efficiency was achieved for perovskite solar cells (PSCs) 3.5%–27%. The charge extraction by the selective contacts controls the efficiency. By its performance, the hole transport materials (HTMs) for PSC have attracted worldwide researchers.

A Review of CZTS Thin‐Film Solar Cells Using Tandem and Multijunction Structures

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Copper zinc tin sulfide (CZTS) is an earth‐abundant, nontoxic, and cost‐effective absorber material that has gained significant attention as a sustainable alternative to CIGS and CdTe in thin‐film photovoltaics (PVs). With a direct bandgap of 1.4–1.5 eV and a high absorption coefficient exceeding 104 cm−1, CZTS is well suited for both single‐junction ...

Composition variations in Cu2ZnSnSe4 thin films analyzed by X-ray diffraction, energy dispersive X-ray spectroscopy, particle induced X-ray emission, photoluminescence, and Raman spectroscopy [PDF]

, 2014
Compositional and structural studies of Cu2ZnSnSe4 (CZTSe) thin films were carried out by X-ray diffraction, energy dispersive X-ray spectroscopy (EDS), particle induced X-ray emission (PIXE), photoluminescence, and Raman spectroscopy. CZTSe thin films

Band Alignment Engineering of Cu‐Based Hole Transport Layers for High‐Efficiency CZTS Thin‐Film Solar Cells: A SCAPS‐1D Simulation Analysis

International Journal of Photoenergy, Volume 2026, Issue 1, 2026.
The practical efficiency of Cu2ZnSnS4 (CZTS) thin‐film solar cells remains constrained by unfavorable band alignment, high defect densities, and inefficient charge extraction at interfaces. This study numerically investigates and optimizes CZTS‐based solar cells by evaluating four Cu‐based hole transport layers (HTLs)—Cu2O, CuO, CuI, and CuSCN—to ...

Physical routes for the synthesis of kesterite

Journal of Physics: Energy, 2019
Abstract This paper provides an overview of the physical vapor technologies used to synthesize Cu2ZnSn(S,Se)4 thin films as absorber layers for photovoltaic applications. Through the years, CZT(S,Se) thin films have been fabricated using sequential stacking or co-sputtering of precursors as well as using sequential or co-evaporation of ...
