Abstract Perovskite solar cells (PSCs) have shown a significant increase in power conversion efficiency (PCE) under laboratory circumstances from 2006 to the present, rising 3.8% an astonishing 25%. This scientific breakthrough corresponds changing energy situation and industrial potential. The flexible perovskite cell (FPSC), which capitalizes on benefits of thin-film deposition operates at low temperatures, is key this transition. FPSC strategically important for large-scale deployment...
This study presents the fabrication, characterization, and optimization of planar-heterojunction Cs₃Bi₂I₉ perovskite solar cells, supported by SCAPS-1D simulations. Experimental results reveal that among fabricated devices (A1, A2, A3), sample A3 demonstrates highest efficiency, with a 0.72% improvement over its counterparts. superior performance is attributed to larger crystallite size, reduced strain, minimal dislocation density, enhanced carrier mobility. These properties collectively...

High-performance perovskite solar cells have attracted increased attention for photovoltaic applications and potentially replacing the predecessor generations. Nevertheless, stability issues lead content has always been among major concerns that barriers from commercialization. This review presents discussion towards inherent instability of development with their performance challenges. The degradation active layer would release toxic substance into environment. low-toxic, lead-free...
Significant progress has been made over the years to improve stability and efficiency of rapidly evolving tin-based perovskite solar cells (PSCs). One powerful approach enhance performance these PSCs is through compositional engineering techniques, specifically by incorporating a mixed cation system at A-site B-site structure tin perovskite. These approaches will pave way for unlocking full potential PSCs. Therefore, in this study, theoretical investigation A-cations (FA, MA, EA, Cs) with...
Abstract The obstacle to the industrialization of perovskite solar cells (PSC) technology lies in their stability. This work rationalizes PSC design with employment 2D-MoS 2 as hybrid hole transport layer (HTL). MoS was selected due its unique optoelectronic and mechanical properties that could enhance extraction thus boost performance stability devices. Five concentrations indicated nanosheets were directly deposited onto via facile spin coating method. electrochemical exfoliation liquid...
Flexible perovskite solar cells (FPSCs) offer significant versatility for portable and wearable technologies owing to their light weight, easy fabrication, low cost, bendable properties. However, the commercialization of FPSCs faces challenges, particularly in terms electron extraction efficiency charge recombination, which impact device stability. Traditional high-temperature annealing methods are impractical due high energy consumption environmental concerns. This study introduces a novel...

Dyes extracted from rengas (Gluta spp.) and mengkulang (Heritiera elata) wood were investigated as sensitizers in dye-sensitized solar cells (DSSCs). Three types of sensitizers, including individual sensitizer, mixture co-sensitizer, exhibited different patterns absorption properties under UV-Vis spectroscopy. The incident photon-to-current efficiency (IPCE) was analyzed via spectral response to examine the generation photocurrent. Because sensitized DSSCs obtained broader spectra, they...
High-performance electron transport layer (ETL) anode generally needs to form a uniform dense with suitable conduction band position and good properties. The TiO2 photoanode is primarily applied as the ETL because it low-cost, has diverse thin-film preparation methods chemical stability. However, pure not an ideal lacks several important criteria, such low conductivity mismatch compositional-tailored perovskite. Thus, inefficient photo-anode or for high-performance perovskite devices. In...
