Abstract Understanding carrier loss mechanisms at microscopic regions is imperative for the development of high-performance polycrystalline inorganic thin-film solar cells. Despite progress achieved kesterite, a promising environmentally benign and earth-abundant photovoltaic material, their impact on device performance remain largely unknown. Herein, we unveil these in state-of-the-art Cu 2 ZnSnSe 4 (CZTSe) cells using framework that integrates multiple macroscopic characterizations with...
Abstract Kesterite is an earth‐abundant energy material with high predicted power conversion efficiency, making it a sustainable and promising option for photovoltaics. However, large open circuit voltage V oc deficit due to non‐radiative recombination at intrinsic defects remains major hurdle, limiting device performance. Incorporating Ge into the kesterite structure emerges as effective approach enhancing performance by manipulating morphology. Herein, how different amounts of affect...
Abstract The performance of kesterite Cu 2 ZnSn(S,Se) 4 (CZTSSe) solar cell is known to be severely limited by the nonradiative recombination near heterojunction interface and within bulk CZTSSe absorber resulting from abundant centers carrier collection efficiency. Herein, simultaneously reduced incorporating small amounts Ge Cd into absorber. Incorporation effectively increases p‐type doping, thus successfully improving conductance reducing in via enhanced quasi‐Fermi level splitting,...
Thin-film solar cells are expected to play a significant role in the space industry, building integrated photovoltaic (BIPV), indoor applications, and tandem cells, where bifaciality semitransparency highly desired. Sb2 (S,Se)3 has emerged as promising new (PV) material for its high absorption coefficient, tunable bandgap, nontoxic earth-abundant constituents. However, high-efficiency exclusively employ monofacial architectures, leaving considerable gap toward large-scale application...

The persistent double layer structure whereby two layers with different properties form at the front and rear of absorbers is a critical challenge in field kesterite thin-film solar cells, which imposes additional nonradiative recombination quasi-neutral region potential limitation to transport hole carriers. Herein, an effective model for growing monolayer CZTSe thin-films based on metal precursors large grains spanning whole film developed. Voids fine grain are avoided successfully by...
Small grain size and near-horizontal boundaries are known to be detrimental the carrier collection efficiency device performance of pure-sulfide Cu2 ZnSnS4 (CZTS) solar cells. However, forming large grains spanning absorber layer while maintaining high electronic quality is challenging particularly for pure sulfide CZTS. Herein, a liquid-phase-assisted growth (LGG) model that enables formation across CZTS without compromising demonstrated. By introducing Ge-alloyed nanoparticle at bottom...
This work designed a nanostructured hybrid catalytic layer on commercial Si absorber to empower the artificial leaf for solar-driven ammonia and value-added chemicals production.
Understanding the elemental composition and point defect properties is crucial for improving device performance in Chalcogenide thin film solar cells. The correlation between characteristics of CuSbS2 sulfurized from metallic precursors was systematically investigated. Interestingly, it found that polycrystalline maintains an overall Cu-rich with a Cu/Sb ratio greater than 1, regardless initial precursor compositions. Besides, no obvious difference integrated devices observed, due to similar...
Abstract High‐performance photovoltaic (PV) devices require optimal carrier‐transport properties and minimized carrier recombination. However, these two factors are found entangled in Cu 2 ZnSnS 4 (CZTS) solar cells due to the unintentionally introduced Na interstitial defects. The interstitials behave as shallow donors which can charge‐passivate acceptor‐like interfacial defects but reduce hole density electron mobility—suppressing recombination whilst hampering transport bulk of CZTS....
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 cells using a newly introduced moisture‐assisted post‐deposition annealing treatment reported. This...
The formation mechanisms of voids and pin-holes in CuSbS 2 thin film synthesized by sulfurizing a co-sputtered Cu–Sb metallic precursor were systematically investigated via quasi situ method.
Abstract Carrier loss mechanisms at microscopic regions is imperative for high-performance polycrystalline inorganic thin-film solar cells.
