Summary: This study reports the multifunctional properties of lead-free BiFeO3-La (BFO-La) thin films, with a focus on the effects of lanthanum doping on structural and optical properties. Lanthanum doping was found to significantly affect defect concentrations, crystallinity, and optical absorption properties of the thin films. The Bi1-xLaxFeO3 (x = 0-20) compositions showed lower direct bandgap values and are considered potential candidate materials for high-performance photovoltaic devices.

Summary: The synthesis of SnS/Ag/SnS trilayer films by RF sputtering method for photovoltaic applications is reported in this study. The addition of Ag thin film improved the physical properties of the SnS film, resulting in higher short circuit current density and efficiency for the trilayer film solar cell compared to the SnS film solar cell. The higher photocurrent density was mainly attributed to enhanced separation efficiency of electron-hole pairs, reduced trapping of charge carriers, and decreased leakage current.

Summary: This study investigates the impact of an additional inorganic CuS layer on the charge transport properties between the ITO electrode and the organic material 2,7,12,17-tetra-tert-butyl-5,10,15,20-tetraaza-21H,23H-porphine (TTBTP). The findings show that the addition of the inorganic CuS layer reduces the built-in voltage and affects the values of Rs, Rsh, and n. The dark current density and applied voltage relationship confirms the theory of thermionic emission, while the power-law relation indicates a space charge limited current controlled by a distribution of trap levels. Furthermore, the additional inorganic layer enhances the photosensitivity, short-circuit current density, open-circuit voltage, and power conversion efficiency.

Summary: In this study, a highly-efficient quantum dot hierarchical film was developed to enhance the performance of photovoltaic devices. By integrating quantum dots with micro/nano hierarchical structures, the film achieved low reflectance for incident light and high reflectance for escape light, resulting in increased absorption of photovoltaics at wide incident angles. The hierarchical structure also restricted the outward release of converted quantum dot photoluminescence, ensuring higher availability of down-shifted photons to photovoltaics. Experimental results showed that applying this film on both sides of bifacial semi-transparent dye-sensitized solar cells improved the short-circuit current density by up to 25.97% under AM 1.5G illumination. This study provides a new perspective on advanced spectral converting layers and practical viability for various optoelectronic devices.
