Advanced Optoelectronic Modeling and Optimization of HTL-Free FASnI/C60 Perovskite Solar Cell Architecture for Superior Performance.

In this study, a novel perovskite solar cell (PSC) architecture is presented that utilizes an HTL-free configuration with formamide tin iodide (FASnI) as the active layer and fullerene (C60) as the electron transport layer (ETL), which represents a pioneering approach within the field. The elimination of hole transport layers (HTLs) reduces complexity and cost in PSC heterojunction structures, resulting in a simplified and more cost-effective PSC structure. In this context, an HTL-free tin HC(NH)SnI-based PSC was simulated using the solar cell capacitance simulator (SCAPS) within a one-dimensional framework.

Improving Photovoltaic Performance of Hybrid Organic-Inorganic MAGeI Perovskite Solar Cells via Numerical Optimization of Carrier Transport Materials (HTLs/ETLs).

In this study, a hybrid organic-inorganic perovskite solar cell (PSC) based on methylammonium germanium triiodide (MAGeI), which is composed of methylammonium (CH3NH3+) cations and germanium triiodide (GeI3-) anions, has been numerically studied using SCAPS-1d codes. An extensive investigation of various electron transport layers (ETLs) and hole transport layers (HTLs) was conducted to identify the most optimal device configuration. The FTO/ZnOS/MAGeI/PEDOT-WO structure performed the highest efficiency of all combinations tested, with an impressive optimized efficiency of 15.

Simple rapid stabilization method through citric acid modification for magnetite nanoparticles.

A highly stable and magnetized citric acid (CA)-functionalized iron oxide aqueous colloidal solution (FeO@CA) was synthesized by using a simple and rapid method of one-step co-participation via a chemical reaction between Fe and Fe in a NaOH solution at 65 °C, followed by CA addition to functionalize the FeO surface in 25 min. The NPs were synthesized at lower temperatures and shortened time compared with conventional methods. Surface functionalization is highly suggested because bare FeO nanoparticles (FeO NPs) are frequently deficient due to their low stability and hydrophilicity.

Encapsulation efficacy of natural and synthetic photosensitizers by silica nanoparticles for photodynamic applications.

This study analysed the physical effects of Cichorium Pumilum (CP), as a natural photosensitizer (PS), and Protoporphyrin IX (PpIX), as a synthetic PS, encapsulated with silica nanoparticles (SiNPs) in photodynamic therapy. The optimum concentrations of CP and PpIX, needed to destroy Red Blood Cells (RBC), were determined and the efficacy of encapsulated CP and PpIX were compared with naked CP and PpIX was verified. The results confirmed the applicability of CP and PpIX encapsulated in SiNPs on RBCs, and established a relationship between the encapsulated CP and PpIX concentration and the time required to rupture 50% of the RBCs (t50).
