Special Issue Information

Dear Colleagues,

In the past few decades, extensive efforts have been employed to synthesize new materials to develop clean energy technologies that satisfy the growing energetic demand and reduce the economic and environmental impacts due to the use of fossil fuels. Since solar radiation on Earth surface represents one of the most affordable and available energy sources, it suggests the idea of improving solar-driven systems for renewable energy production and storage. The aim of this Special Issue is to address new insights into solar energy conversion and, in particular, solar cell applications, thanks to the advanced studies led in the material science field, which covers all the subjects related to physics phenomena comprehension (light absorption, transport phenomena, optical properties, materials coupling, potential barriers overcome, etc.),  Chemistry application (synthesis of new materials, composite, catalysts, etc.) and device fabrication (bulk materials, coatings, thin films, and/or surface treatments).

Particular interest is devoted to solar cells, starting from their electrode material composition study (single crystal or polycrystalline, amorphous materials, employing homo and/or heterojunctions, Schottky barriers, polimer/liquid junctions, etc.), their component analysis, individual cells and/or complete photovoltaic modules (solar panels), including their economic aspects and scale-up possibilities.

Apart from solar cells, also photothermal (solar absorber, heat storage materials, radiative cooling systems, etc.), photochemical and photoelectrochemical devices (photoelectrodes, photocatalysis, etc.) are highly welcomed, due to the great impact that their applications can imply in reaching the goal of renewable materials exploitation and application.

To reach this goal, a synergistic work has to be done by coupling experimental and theoretical approaches. Cutting-edge experimental techniques, such as electron microscopies and spectroscopies, morphological analysis, in combination with theoretical modelling (quantum mechanical and finite-element calculations) are needed.

This short introduction to this Special Issue only scratches the surface of all the concepts developed to date, which represent the paper arguments we are calling for.

Wide bandgap (Eg) perovskite solar cells (PSCs) are emerging as the preferred choice for top cells in a tandem architecture with crystalline silicon solar cells. Among the wide bandgap perovskites, a mixed cation mixed halide composition containing CsyFA1-yPbI3−xBrx is a popular choice because the presence of bromine widens the bandgap and addition of cesium stabilizes the crystal structure. These perovskite layers are commonly fabricated using one-step spin coating technique; however, sequential spin coating followed by dip coating has been successful in offering better control over the crystallization process for low bandgap absorber layers. In this paper, the fabrication of a Cs0.2FA0.8PbI3−xBrx perovskite absorber layer using the sequential deposition route is reported. The concentration of bromine was varied in the range 0 ≤ x ≤ 1 and optical, structural, and morphological properties of the films were studied. As the concentration was increased, the perovskite showed better crystallinity and the presence of large grains with high surface roughness, indicating the formation of the CsPbBr3 phase. Optically, the perovskite films exhibited higher absorbance in the ultraviolet (UV) range between 300 and 500 nm, hence up to x = 0.3 they can be profitably employed as a wide bandgap photon absorber layer in solar cell applications.
