“…Meanwhile, the reduction (quenching) of the peak in the samples Cu(0) and Cu(1) means the reduction of recombination . Since the E g of P3HT:PCBM is ∼1.80 eV, the peak at 690 nm indicates the transition from band to band P3HT:PCBM . The recombination in the range of 400–600 nm is related to the recombination in the energy ranges less than E g and is done through the transfer between the conduction band and the trap level or from the trap level to the valance band.…”

According to the PL spectra, the red shift by the addition of Cu concentration(s) may be due to the indirect recombination of electrons moving from the trap level formed by Cu atoms to holes in the valence band.…”

In this research work, un- and copper (Cu)-doped tin sulfide (SnS) nanoparticles (NPs) with various Cu concentrations were synthesized by the ultrasonic method and added to the active layer of polymer solar cells with the ITO/PEDOT:PSS/P3HT:PCBM/Ag–Al configuration. The structural, optical, and electrical properties related to the effect of these NPs on cell performance were investigated. X-ray diffraction of these NPs indicates the formation of orthorhombic polycrystalline SnS. The field emission scanning electron microscopy image showed that the un- and Cu-doped SnS NPs were spherical particles with a size less than 100 nm. Optical analysis of the cells shows that the optical energy band gap decreases due to the presence of NPs. The electrical properties of the samples, such as diode coefficient (n), reverse saturation current, turn-on potential (V t), and mobility (μ), were measured using the J–V curve at the dark condition. Electrical characterization of the samples showed that the performance of the cells was improved by adding SnS NPs to the active layer.

“…Studies have already been conducted to determine the levels of intrinsic/extrinsic defects in SnS films using PL measurements. [29][30][31][32][33][34] However, very few studies have been conducted on the p-n interface in an SnS film. 9) This knowledge is crucial for improving the device performance because carriers originate from the defects around the p-n interface.…”

The fundamental defects around the p–n interface were analyzed based on low temperature photoluminescence (LT-PL) measurements to determine the origin of the various defects around the n-CdS/p-SnS structure in tin sulfide (SnS) solar cells. Particularly, the effects of Cd, S, and Na atoms on PL at the interface of a CdS layer and various treated SnS layers were examined. The PL peaks at 1.08 eV and 1.23 eV in the CdS/SnS structure, which were observed using the Cd partial electrolyte-treated SnS film, were associated with the formation of Cd-related defects. Furthermore, the PL peak at 1.27 eV in the CdS/SnS structure, which was observed using the sulfurized SnS film and the excess Na diffused SnS film, was associated with the formation of S-related defects such as OS defects. These findings present considerable potential for improving the efficiency of SnS solar cells.
