abstract = {Bulky 2D alkylammonium cations in metal halide perovskites offer a route to improve both structural stability and optoelectronic performance. This study systematically explores the incorporation of alkylammonium iodides with different chain lengths─dodecylammonium (C12), hexadecylammonium (C16), and octadecylammonium (C18)─into perovskite films for solar cells. Using spectroscopic and nanoscale characterization techniques, we show that C12 provides the best results: enhanced [111] orientation, reduced nonradiative recombination, uniform cation distribution, and improved vertical conductivity. Nanoscale X-ray diffraction and AFM-based infrared spectroscopy revealed that intermediate chain lengths enable favorable lattice expansion and interfacial passivation without hindering crystal growth. Solar cells based on C12-modified films reached power conversion efficiencies over 20%, surpassing both pristine and longer-chain formulations. These findings demonstrate that tuning alkyl chain length is an effective molecular design strategy to guide perovskite crystallization and improve device performance and stability.},

abstract = {Abstract Photoelectrodes based on earth-abundant elements, FTO|BiVO4 and Nifoam|Cu2O/CuO/TiO2, were assembled in a parallel-configured flow photoelectrochemical (PEC) electrolyser and provided unassisted conversion of glycerol and CO2 into value-added chemicals under solar-simulated irradiation. The photoelectrodes PEC properties were firstly evaluated in aqueous NaHCO3 electrolyte, using platinum as auxiliary electrode, for determination of wavelength-resolved light harvesting, flat band potential, conduction and valence band edges, charge-separation and injection efficiencies. Comparison of Nifoam|Cu2O, Nifoam|Cu2O/CuO and Nifoam|Cu2O/CuO/TiO2 for PEC CO2 reduction revealed that Cu2O/CuO improved light harvesting and selectivity for ethanol production, while TiO2 protected the photocathode against photodegradation. Under illumination, the PEC flow electrolyser assembled with FTO|BiVO4 and Nifoam|Cu2O/CuO/TiO2 exhibited + 0.56 V of open-circuit photovoltage and a spontaneous short-circuit photocurrent (1.7 to 1 mA in 2 h), attributed to the suitable alignment of the band edges of these photoelectrodes. After 2 h PEC electrolysis, formate (229 µg cm−2 h−1) and glycolate (58.5 µg cm−2 h−1) were produced in the anodic compartment with faradaic efficiencies of 69% and 13%, respectively. The cathodic compartment generated 26 µg cm−2 h−1 of ethanol (FE = 32%). This flow PEC electrolyser demonstrates a proof-of-concept for a practical solar-to-chemicals production using industrial by-products as feedstocks.},

abstract = {Interfacial defects at the buried junction between the electron transport layer (ETL) and perovskite absorber critically hinder the performance of perovskite solar cells (PSCs). In this work, we report that a CdS quantum dot (QD) interlayer, deposited onto SnO2 via a scalable successive ionic layer adsorption and reaction (SILAR) method, provides a practical and scalable strategy to improve charge transport across this interface. The CdS QD layer not only suppresses oxygen vacancies but also reacts with hydroxyl groups on the SnO2 surface, thereby improving surface potential uniformity and enhancing the electron extraction rate. Impedance spectroscopy further confirms improved interface homogeneity and charge transport, which correlate with higher fill factor and short-circuit current density. As a result, CdS modification enables a ∼25 % efficiency enhancement on PSCs, highlighting the potential of QD-based interfacial engineering towards high-performance PSCs.},

abstract = {Perovskite solar cells (PSCs) have attracted significant attention over the past decade due to their high performance. However, challenges such as moisture sensitivity and the toxicity of certain constituents remain barriers to their commercialization. Tin, germanium, and other elements with optoelectronic properties similar to those of lead have emerged as promising substitutes for the B-site metal in PSCs. Theoretical studies have played a crucial role in elucidating how specific material and structural parameters influence photovoltaic behavior. Among the most prominent tools for simulating thin-film solar cells in recent years, open-source SCAPS-1D software stands out as a valuable resource. Therefore, this article presents a comprehensive review of 54 simulation studies, using SCAPS-1D, published between 2016 and 2025, focusing on lead-free PSCs. In total, 26 studies on Sn-based PSCs and 28 on perovskites with alternative B-site metals were analyzed to evaluate how simulations have contributed to understanding device performance with lead substitutes. This review also provides an overview of the current research landscape and highlights promising directions for advancing environmentally benign, lead-free PSCs through SCAPS modeling. The studies discussed in this review show a prevailing tendency to simulate PSCs in regular rather than inverted configuration. In many cases, the defect density assumed for the absorber layer is set at ideal values or even below 1013 cm−3, which potentially limits the accuracy of predictions. Among the strategies adopted to improve performance, composition engineering emerged as the most prominent.},

abstract = {Perovskite solar cells have attracted attention in recent years due to their low-cost fabrication and high-power conversion efficiency. For practical applications, however, long-term stability is still a problem. The perovskite layer degrades when exposed to moisture, oxygen, temperature and UV radiation. One strategy to overcome this limitation is the modification/passivation of the perovskite layer. The use of chelatogenic molecules is an effective method because their functional groups can coordinate with the metallic center (Pb2+) of the perovskite, thereby enhancing its structural stability. Herein, we demonstrate the effect of incorporating N,N′-bis(salicylidene)-o-phenylenediamin (salophen) molecules (a Schiff base) on methylammonium lead iodide perovskite (MAPbI3) thin films. Salophen was dissolved in ethyl acetate solvent at five different concentrations and spin-coated onto MAPbI3 during the antisolvent step under ambient conditions (room temperature; relative humidity over 50%). X-ray diffractograms reveal that the addition of salophen molecules on the top of the MAPbI3 films induces better crystallization of the perovskite α-phase, eliminating the residual amount of PbI2, which simultaneously creates a hydrophobic protective surface. Steady-state photophysical characterization shows that the salophen molecules did not significantly change the optical properties of the MAPbI3 films. Nonetheless, time-resolved photoluminescence decays clearly exhibit a charge-carrier extraction pathway through the salophen passivation of MAPbI3 defects while enhancing thin film organization, a behaviour proven with surface electron microscopy images. Device efficiencies reached values higher than 18%, along with gains in stability.},

abstract = {To accelerate commercialization of perovskite technology and its use in multiple application fields, several device processing strategies have been developed. These efforts primarily target scaling-up device fabrication for mass production and enhancing performance for different light sources (sun or indoor light). This work presents a novel 3D/2D perovskite heterostructure by depositing a mixed layer of phenethylammonium iodide (PEAI) and 1,8-diiodooctane (DIO) directly atop the 3D perovskite absorber without a further annealing step. The addition of DIO enables the formation of pure 2D PEA₂PbI₄ 4 (n = 1) at room temperature, leading to defect passivation of 3D perovskite surface, improvement in the crystallinity of 2D perovskite, and optimizing the dipole moment at perovskite/hole transport interface. Large-area PSC modules treated with PEAI:DIO achieve remarkable power conversion efficiencies of 17.7 % (32 cm²) and 15.6 % (121 cm²) under 1Sun irradiation. When exposed to indoor illumination with various LED intensities (200, 500 and 1000 lux) the PEAI:DIO engineered module demonstrated efficiency approaching 34 %, among the highest reported so far for large area modules employing perovskite with bandgap below 1.7 eV. Long-term stability tests following the ISOS-D-1 protocol reveal a threefold increase in T80 lifetime compared to untreated devices.},
