Using first-principles density functional calculations, we investigate the structure and properties of previously unstudied grain boundaries (GBs) in solar absorber material copper-zinc-tin-sulfide (CZTS). We identify four stable low-Σ value symmetric tilt GBs with low formation energies: Σ3 (111) Σ5 (201), each two different GB terminations. Compared to CdTe CuInSe, quaternary semiconductor CZ...

The solar cell CZTS / CZTSe was studied using SCAPS-1D * computer simulator. It noted that increasing the thickness of absorber layer p-CZTSe from 250nm to 5μm leads increase IV curve. thus values Voc, Jsc, FF

In this paper, we simulated a double junction cell based on top CdS/Cu2ZnSnS4 cell, stacked bottom CdS/Cu2ZnSnSe4 cell. We started by studying the perfomance of solar copper zinc tin selenide Cu2ZnSnSe4 (CZTSe) absorber. Then, evaluated photovoltaic parameters tandem at optimized thickness sulfide Cu2ZnSnS4 (CZTS) absorber where and cells deliver same photocurrent density. achieved A maximum ef...

Fabrication of environmentally safe C2ZnSnS4 (CZTS) photovoltaic thin films pure kesterite state is crucial. We have preparedCZTS by sol-gel dip-coating process from chloride-based chemicals. After vacuum-annealed at 550°C, the optical andstructural characters were further examined UV–vis spectroscopy, X-ray diffraction (XRD), scanning electronmicroscopy (SEM), and energy dispersive spectroscop...

Detection of X- and gamma-rays is essential to a wide range applications from medical imaging high energy physics, astronomy, homeland security. Cadmium zinc telluride (CZT) the most widely used material for room-temperature detector has been fulfilling requirements growing detection demands over last three decades. However, CZT still suffers presence density performance-limiting defects, such ...

Kesterite Cu 2 ZnSnS 4 (CZTS), with direct and tunable bandgap, high absorption coefficient, low-cost processing, earth-abundance, non-toxicity, has become a promising absorber material for emerging thin film solar cells. The growth, phase formation, stoichiometry, as well the electrical optical properties of sputtered grown CZTS films, are greatly influenced by annealing temperature pressure. ...

Abstract Sulfide kesterite Cu 2 ZnSnS 4 (CZTS) solar cells, containing earth‐abundant and environmentally benign constituents, are regarded as promising candidates for thin‐film photovoltaic technologies. CZTS device performance, however, is currently limited by severe nonradiative recombination caused abundant deep‐level defects. Herein, an effective defect engineering approach high bandgap ce...
