we present the influences of the solvent, concentration, and spin rates of 3,9-bis(2-methylene-(3-(1,1-dicyanomethylene)-indanone))-5,5,11,11-tetrakis(4-hexylphenyl)-dithieno[2,3-d:2',3'-d']-s-indaceno[1,2-b:5,6-b']dithiophene) (ITIC) material on the performances of perovskite solar cells (PSCs). The device parameters such as open-circuit voltage (Voc), short circuit current (Jsc), fill factor (FF), and power conversion efficiency (PCE) were measured with Keithley 2400 source meter unit under 100 mW/cm (AM 1.5 G). The data in this article describe the optimization of ITIC-based PSCs and are directly related to our research article "Non-fullerene-based small molecules as an efficient n-type electron transporting layers in inverted organic-inorganic halide perovskite solar cells" (Noh et al., Submitted for publication) [1].

ABSchalcogenide perovskites (CPs) are emerging as promising alternatives to lead halide perovskites due to their unique properties. However, their bandgap exceeds the Shockley-Queisser limit. By substituting S with Se, the bandgap is significantly reduced, shifting it from the visible into the near-infrared region.

KOBu-promoted [3 + 2] cycloaddition of dimethyl sulfoxide (DMSO) with fullerenes has been developed for facile and efficient one-pot synthesis of 1,2,3,4-cyclic sulfoxide-fused [60]/[70]fullerene dihydrides, which offers a versatile platform for the site-selective preparation of various fullerene multiadducts with a wide range of functional groups. The utility of these tetra-functionalized fullerenes is demonstrated by the successful application as electron-transport materials in perovskite solar cells.

Thermal co-evaporation of halide perovskites is a solution-free, conformal, scalable, and controllable deposition technique with great potential for commercial applications, particularly in multi-junction solar cells. Monolithic triple-junction perovskite solar cells have garnered significant attention because they can achieve very high efficiencies. Nevertheless, challenges arise in fabricating these devices, as they require multiple layers and precise current matching across complex absorber stacks.

The growing demand for efficient, stable, and environmentally friendly photovoltaic technologies has motivated the exploration of nontoxic perovskite materials such as KGeCl. However, the performance of KGeCl-based perovskite solar cells (PSCs) depends heavily on the compatibility of charge transport layers (CTLs) and optimization of device parameters. In this study, six PSC configurations were simulated using SCAPS-1D software, incorporating CTLs such as Alq, CSTO, VO, PB, and SbS.

A strong n-type perovskite layer is crucial in achieving high open-circuit voltage (V) and power conversion efficiency (PCE) in the p-i-n solar cells, as the weak n-type perovskites result in a loss of V, and the p-type perovskites contain numerous electron traps that cause the severe carrier recombination. Here, three types of perylene diimide (PDI) based small molecule dopants with different dimensions, including 1D-PDI, 2D-PDI, and 3D-PDI are designed, to produce heavier n-type perovskites. The PDI-based molecules with Selenium atoms have a strong electron-donating ability, effectively enlarging the quasi-Fermi level splitting within the perovskites.
