Mechanosynthesis of Layered Double Perovskites with Aromatic Spacer Cations for Lead‐Free Thin‐Film Opto(electro)ionics

2026

Abstract

In the quest for stable, eco‐friendly, lead‐free halide perovskites, layered double perovskite semiconductors are promising derivatives that remain underexploited. We demonstrate the use of mechanosynthesis to access these materials for silver(I) and bismuth(III) analogues incorporating benzylammonium and 1,4‐phenylenedimethylammonium bromide cations in Ruddlesden–Popper and Dion–Jacobson phases, respectively. Their thin films were fabricated and analysed by a combination of techniques, demonstrating the potential use in thin‐film opto(electro)ionics.

Thin-film solar cell

Thin-film solar cells are made by depositing one or more thin layers (thin films or TFs) of photovoltaic material onto a substrate, such as glass, plastic or metal. Thin-film solar cells are typically a few nanometers (nm) to a few microns (μm) thick–much thinner than the wafers used in conventional crystalline silicon (c-Si) based solar cells, which can be up to 200 μm thick. Thin-film solar cells are commercially used in several technologies, including cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous thin-film silicon (a-Si, TF-Si).

Perovskite solar cell

A perovskite solar cell (PSC) is a type of solar cell that includes a perovskite-structured compound, most commonly a hybrid organic–inorganic lead or tin halide-based material as the light-harvesting active layer. Perovskite materials, such as methylammonium lead halides and all-inorganic cesium lead halide, are cheap to produce and simple to manufacture. Solar-cell efficiencies of laboratory-scale devices using these materials have increased from 3.8% in 2009 to 25.

Timeline of solar cells

In the 19th century, it was observed that the sunlight striking certain materials generates detectable electric current – the photoelectric effect. This discovery laid the foundation for solar cells. Solar cells have gone on to be used in many applications. They have historically been used in situations where electrical power from the grid was unavailable. As the invention was brought out it made solar cells as a prominent utilization for power generation for satellites.
