Special Issue Information

Dear Colleagues,

Perovskites are materials that adopt the same crystal structure as calcium titanate (CaTiO3), namely, ABX3. There are hundreds of different materials that adopt this structure and with multiple properties, but in this Special Issue, the papers that study preparation and characterization of the perovskite materials with properties essential for photovoltaic application are appreciated.

Perovskite solar cells (PSCs) is the term used for photovoltaic cells with hybrid organic–inorganic perovskite as absorbing material, so papers studying the formation, structure, and morphology of perovskite layers and the optimization of bandgap, efficiency, toxicity, long-term stability, hysteresis in current–voltage characteristics, and other properties of PSCs are broadly welcomed. The topics relevant to the issue also include the investigation of other materials having perovskite structures, including inorganic perovskites, for building into photovoltaic devices as any other layer of the solar cell.

The papers that study innovative perovskite materials for use in photovoltaic applications as well as examination of their structural, optical, electrical, and other properties important for photovoltaic application are also of interest. This Special Issue welcomes manuscripts that include correlation of the functional properties of perovskite materials with chemical composition, micro- and nanostructure, morphology, and preparation methods.

Theoretical studies aiming to predict preferred properties for the photovoltaic application of perovskite materials are also in the scope of this Special Issue.

It is my pleasure to invite you to submit a manuscript to this Special Issue. Full papers, communications, and reviews are all welcome.

With the aim of decreasing the number of experiments to obtain a perovskite solar cell (PSC) with maximum theoretical efficiency, in this paper, PSC performance was studied using the program solar cell capacitance simulator (SCAPS-1D). The PSC with the architecture ITO/TiO2/perovskite/spiro-MeOTAD/Au was investigated, while the selected perovskite was mixed cation Rb0.05Cs0.1FA0.85PbI3. The analysis was based on an experimentally prepared solar cell with a power conversion efficiency of ~7%. The PSC performance, verified by short-circuit current density (Jsc), open-circuit voltage (Voc), fill factor (FF) and power conversion efficiency (PCE), was studied by optimization of the simulation parameters responsible for improvement of the cell operation. The optimized parameters were absorber layer thickness, doping, defect concentration and the influence of the resistivity (the net effect of ohmic loss, Rs and the leakage current loss represented by the resistivity, Rshunt). The results of SCAPS-1D simulations estimated the theoretical power conversion efficiency of 15% for our material. We have showed that the main contribution to improvement of solar cell efficiency comes with lowering ohmic resistivity of the cell as well as doping and defect concentration, because their concentration is proportional to recombination rate.

In this paper, we studied the influence of polyvinylpyrrolidone (PVP) as a stabilization additive on optical and electrical properties of perovskite formamidinium lead iodide (FAPI) polycrystalline thin films on ZnO nanorods (ZNR). FAPI (as an active layer) was deposited from a single solution on ZNR (low temperature processed electron transport layer) using a one-step method with the inclusion of an anti-solvent. The role of PVP in the formation of the active layer was investigated by scanning electron microscopy and contact angle measurements to observe the effect on morphology, while X-ray diffraction was used as a method to study the stability of the film in an ambient environment. The effect of the PVP additive on the optical and electrical properties of the perovskite thin films was studied via photoluminescence, UV-Vis measurements, and electrical impedance spectroscopy. We have demonstrated that PVP inclusion in solution-processed perovskite FAPI thin films prevents the degradation of the film in an ambient atmosphere after aging for 2 months. The inclusion of the PVP also improves the infiltration of FAPI perovskite into ZnO nanostructures, increases electrical conductivity and radiative recombination of the photo-generated charge carriers. These results show promising information for promoting PVP stabilized FAPI perovskites for the new generation of photovoltaic devices. Full article
