Abstract Exhibiting outstanding optoelectronic properties, antimony selenide (Sb 2 Se 3 ) has attracted considerable interest and been developed as a light absorber layer for thin‐film solar cells over the decade. However, current state‐of‐the‐art Sb devices suffer from unsatisfactory “cliff‐like” band alignment severe interface recombination loss, which deteriorates device performance. In this study, heterojunction of an cell is improved by introducing effective aluminum (Al 3+ cation into...
Cadmium sulfide (CdS) buffer layer is commonly used in Kesterite Cu2 ZnSn(S,Se)4 (CZTSSe) thin film solar cells. However, the toxicity of (Cd) and perilous waste, which generated during deposition process (chemical bath deposition), narrow bandgap (≈2.4 eV) CdS restrict its large-scale future application. Herein, atomic (ALD) method proposed to deposit zinc-tin-oxide (ZTO) as a Ag-doped CZTSSe It found that ZTO improves band alignment at Ag-CZTSSe/ZTO heterojunction interface. The smaller...
Quasi-two-dimensional (2D) perovskites are highly promising light-harvesting materials for commercialization of perovskite solar cells (PSCs) owing to the excellent stability. However, coexistence multiple n-value species in 2D often causes increased complexities crystallization that can negatively affect eventual photovoltaic performance. Herein, we present a binary solution based strategy via introducing nontoxic and widely accessible CH3COOH (HAc) as co-solvent preparing high-quality...

Abstract Non‐fullerene acceptors are currently a hot research area in the development of organic solar cells (OSCs). At present, the‐state‐of‐the‐art power conversion efficiency (PCE) non‐fullerene (NF‐OSCs) with single and multiple‐junction has surpassed 18% 19%, respectively. The cathode interlayer (CIL) plays significant role improvement PCE stability OSCs. Recently, large number CIL materials have been employed This review summarizes recent progress systematically describes their impact...
Sb2Se3, one of the most desirable absorption materials for next-generation thin-film solar cells, has an excellent photovoltaic characteristic. The [hk1]-oriented (quasi-vertically oriented) Sb2Se3 thin film is more beneficial promoting efficient carrier transport than [hk0]-oriented film. Controlling orientation remains main obstacle to further improvement in efficiency Sb2Se3-based cells. In this work, controlled [hk0] or [hk1] precursor readily adjusted by tuning substrate temperature and...

Abstract While 2D Ruddlesden‐Popper (RP) perovskites exhibit attractive opto‐electronic properties and stability for use in perovskite solar cells (PSCs), their complicated film‐forming processes often induce a non‐negligible level of defects that significantly undermine the power conversion efficiency (PCE) PSCs. Here, two organic ammonium salts with same chain length, namely monoammonium (butylammonium iodide, BAI) diammonium (1,4‐butanediamine dihydroiodide, BDAI 2 ) surface defect...
