Comprehensive investigation of material properties and operational parameters for enhancing performance and stability of FASnI-based perovskite solar cells.

Recent advancements in the efficiency of lead-based halide perovskite solar cells (PSCs), exceeding 25%, have raised concerns about their toxicity and suitability for mass commercialization. As a result, tin-based PSCs have emerged as attractive alternatives. Among diverse types of tin-based PSCs, organic-inorganic metal halide materials, particularly FASnI stands out for high efficiency, remarkable stability, low-cost, and straightforward solution-based fabrication process.

Optical and electronic properties of MgPc-Ch-diisoQ blend organic thin film as an active layer for photovoltaic cells.

Organic photovoltaic cells are a promising technology for generating renewable energy from sunlight. These cells are made from organic materials, such as polymers or small molecules, and can be lightweight, flexible, and low-cost. Here, we have created a novel mixture of magnesium phthalocyanine (MgPc) and chlorophenyl ethyl diisoquinoline (Ch-diisoQ).

Thermally Stable Solution Processed Vanadium Oxide as a Hole Extraction Layer in Organic Solar Cells.

Low-temperature solution-processable vanadium oxide (V₂O) thin films have been employed as hole extraction layers (HELs) in polymer bulk heterojunction solar cells. V₂O films were fabricated in air by spin-coating vanadium(V) oxytriisopropoxide (s-V₂O) at room temperature without the need for further thermal annealing. The deposited vanadium(V) oxytriisopropoxide film undergoes hydrolysis in air, converting to V₂O with optical and electronic properties comparable to vacuum-deposited V₂O₅.
