Abstract Perovskite solar cells (PSCs) are of significant interest for researchers as the next‐generation energy harvesters. However, PSCs suffer from traps that densely distributed at interfaces, which deteriorate device's performance. To address this issue, a new small molecule (DTAQTPPO) capable trap passivation on perovskite layer surface while possessing ambipolar charge extraction properties is designed, endow DTAQTPPO with dual functionality both interface defect passivator and efficient hole/electron extractor in n‐i‐p p‐i‐n architectures.

Abstract Despite well‐matching indoor illumination spectra, the performance of wide bandgap perovskite solar cells (WB‐PSCs) for photovoltaics (i‐PV) is hindered by photo‐induced halide phase segregation and trap‐assisted non‐radiative recombination.

As result, 1.75 eV WB‐PSCs achieve an Power Conversion Efficiency (iPCE) 37.6% under 1000 lux illumination. Under standard sunlight conditions, devices reach (PCE) 20.1% fill factor 78.5%, among best parameters this bandgap. Importantly, passivated exhibit excellent shelf stability, retaining 92% their initial after 3200 h. ambient air conditions at 55 °C, unencapsulated maintained 76% PCE 300 h continuous light soaking. The findings represent significant breakthrough development stable i‐PV applications, with minimized nonradiative losses enhanced performance.

Abstract The copper content in sulfide significantly influences the material properties, potentially affecting interfacial non‐radiative recombination perovskite solar cells. Here, a simple ball‐milling strategy is used to obtain Cu‐poor (cupric sulfide, CuS) and Cu‐rich (cuprous Cu 2 S) nanoparticles (in which CuS S are dominant phases respectively, containing mixture of CuO/Cu(OH) species) from commercial cupric‐ cuprous‐sulfide powders respectively. resulting exhibit well‐crystallized hexagonal structure, suppressing formation harmful byproducts. Additionally, uniformly cover perovskite, effectively addressing residual PbI at grain boundaries constructing hole‐transport channel interface between spiro‐OMeTAD [2,2′,7,7′‐tetrakis (N, N‐di‐p‐methoxyphenylamine)‐9,9′‐spirobifluorene]. In contrast, non‐crystalline structure with excessive Their aggregation non‐uniform morphology on surface likely result charge‐controlled interactions big bond polarity cupric sulfide. Moreover, presence byproducts increases hydrophilic sites, weakening defect passivation compromising device performance.
