“…Interestingly, the interconnected area of the specimen increases with increasing P3HT concentration, which seems to be consistent with the morphological characteristics of spinodal decomposition rather than the nucleation growth mechanism [27]. FigureS6a(Supporting Information) shows the Fourier transform infrared (FTIR) spectra of P3HT/PVK film, the characteristic peaks at the 748 and 807 cm −1 are associated with the bending vibration of hexyl substituent methylene groups -(CH 2 ) 5 and the aromatic C-H out of plane vibration of thiophene ring of P3HT, respectively [28]. Two weaker peaks at 1394 and 1571 cm −1 are corresponding to the aromatic C = C stretching vibrations…”

“…[ 28 ] Two weaker peaks at 1394 and 1571 cm −1 are corresponding to the aromatic C = C stretching vibrations from the 2,3,5‐thiophene ring. [ 28 ] The FTIR results demonstrate that P3HT has been incorporated into perovskite. Analysis of C K‐edge cluster maps (Figure 2e,f) and corresponding X‐ray absorption spectroscopy (XAS) spectra (Figure 2g,h) reveals three distinct clusters representing different carbon components.…”

The best research‐cell efficiency of perovskite solar cells (PSCs) is comparable with that of mature silicon solar cells (SSCs); However, the industrial development of PSCs lags far behind SSCs. PSC is a multiphase and multicomponent system, whose consequent interfacial energy loss and carrier loss seriously affect the performance and stability of devices. Here, by using spinodal decomposition, a spontaneous solid phase segregation process, in situ introduces a poly(3‐hexylthiophene)/perovskite (P3HT/PVK) heterointerface with interpenetrating structure in PSCs. The P3HT/PVK heterointerface tunes the energy alignment, thereby reducing the energy loss at the interface; The P3HT/PVK interpenetrating structure bridges a transport channel, thus decreasing the carrier loss at the interface. The simultaneous mitigation of energy and carrier losses by P3HT/PVK heterointerface enables n‐i‐p geometry device a power conversion efficiency of 24.53% (certified 23.94%) and excellent stability. These findings demonstrate an ingenious strategy to optimize the performance of PSCs by heterointerface via Spinodal decomposition.

“…Optical measurements show a 15 nm blue shift in absorption in P3HT: CdS as compared to pristine P3HT, indicating that charge transfer between P3HT and CdS occurs (Khan & Almohammedi, 2017). On the other hand, the incorporation of CdS into P3HT favours the crystallinity of P3HT chains in the P3HT: CdS nanocomposites, since the peaks ascribed to the crystalline phase are more intense (García-Carvajal et al, 2019). The value of the energy bandgap is calculated using the Tauc relation method, and the initiate wavelength (λinitiate) is calculated according to the Eq.…”

Polymers are flexible materials that can be easily processed and are formed into a thin film by several methods such as spin-coating, dip-coating, film-casting, and printing. The spin coating method has been extensively utilized in fabricating solution-prepared organic/inorganic electronic devices, this technique is positively efficient in generating thin film apart from being a flexible method to execute. In this study, poly(3-hexylthiophene) (P3HT) material is selected as polymer and cadmium sulphide (CdS) as nanoparticles to produce a hybrid nanocomposite thin film through the process spin-coating method. The P3HT and cadmium ion solution were used to fabricate a thin film onto a quartz glass substrate at a spin speed of 500 rpm for 10 seconds. This spin-coated thin film was heated at different temperatures such as 40°C, 80°C, 120°C, and 160°C for optical properties using a UV-Vis spectrophotometer. The UV-Vis absorption spectra of P3HT: CdS indicated absorption peaks in the UV region, which were ascribed to the band gap of the P3HT: CdS thin film. Our results showed that the optical properties of the P3HT: CdS be contingent on the annealing temperature. The film at room temperature yielded a band gap value of 1.98 eV, at 40°C it resulted in 1.99 eV. The band gap value was increased when annealed at 80°C with 2.02 eV. Annealing temperatures were then raised to 120°C and 160°C, leading to band gap values of 3.11 eV and 2.80 eV respectively.
