Summary: In this study, a ZnO-based buffer layer with a polymer-film-modified top interface was proposed to replace CdS in Sb2Se3 photovoltaic devices, addressing the issue of high open-circuit voltage. The addition of a branched polyethylenimine layer at the ZnO and transparent electrode interface enhanced the performance of Sb2Se3 solar cells, resulting in an important increase in open-circuit voltage from 243 mV to 344 mV and a maximum efficiency of 2.4%. This study aims to establish a relation between the use of conjugated polyelectrolyte thin films in chalcogenide photovoltaics and the resulting device improvements.

Summary: The study focused on the optical and structural properties of (CdS)1-x (ZnS)x thin films fabricated by thermal vacuum evaporation, with XRD analysis showing changes in peak intensity and position with increasing ZnS content. Theoretical models were used to estimate solar cell efficiency and short-circuit current density based on experimental data, calculations reflecting optical losses and recombination losses. The films exhibited direct band-to-band transitions, with an increase in optical energy gap and improvements in short-circuit current density and cell efficiency as ZnS content increased.

Summary: We propose a dual-polarization optimization method to improve the bulk sensitivity of silicon-on-insulator (SOI) waveguides by considering the substrate leakage losses. This method is applied to design micro-ring resonator bulk sensors with strip, slot, subwavelength grating, and subwavelength grating slot waveguides. The results show that the subwavelength grating slot waveguide has higher bulk sensitivities of 520 nm/RIU for the TE mode and 325 nm/RIU for the TM mode compared to strip, slot, and subwavelength grating waveguides. Furthermore, Monte Carlo analysis demonstrates that the subwavelength grating slot waveguide has the highest immunity to fabrication errors.

Summary: In this study, the hybrid evaporation-solution method (HESM) was used to develop stable, efficient, and scalable wide-bandgap perovskite solar cells (WBG-PSCs). Bandgaps between 1.55-1.67 eV were achieved by varying CsBr and MABr content. Champion efficiencies of 21.06% and 20.35% were obtained for perovskites with 1.64 and 1.67 eV bandgaps, respectively. Additionally, 18.51%-efficient semi-transparent WBG-PSCs were successfully implemented. This study demonstrates the importance of HESM in enabling scalable, high-performance, and stable WBG-PSCs for tandem configurations and emerging applications.

Summary: Silicon solar cells' efficiency is boosted by utilizing various strategies such as advanced texturing, multilayer anti-reflecting coating, and rear reflectors. Dielectrics deposited under vacuum environments are used to reduce metal absorption. This study shows that solution-based silica aerogel thin film is an ideal candidate for rear reflectors due to its low cost and near unity refractive index. The morphology of the spin-coated aerogel thin films can be controlled by altering solution concentration and spin-coating speed. Incorporating aerogel in silicon heterojunction solar cells also reduces indium consumption required for TCO by more than 50%.

Summary: The optical limiting behavior triggered by nonlinear absorption can be enhanced by incorporating MnO2 nanoparticles into polymer nanofibers. The behavior becomes more pronounced with increasing concentration of MnO2 nanofiller, but weakens at higher input intensity due to the filling of localized defect states by one photon absorption. The composite nanofibers with a higher concentration of MnO2 nanofiller exhibit stronger nonlinear absorption behavior and can be potentially used in optoelectronic applications operating in a wide spectral range.

The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements.
