Special Issue Information

Dear Colleagues,

Perovskite photovoltaics have revolutionized the solar energy landscape, achieving certified power conversion efficiencies exceeding 27% for single-junction devices and exceeding 34% in perovskite-silicon tandems—figures approaching theoretical limits. This unprecedented progress underscores their immense potential for terawatt-scale sustainable energy generation. This Special Issue, titled "Advances in Perovskite Solar Cells: Design, Performance and Applications," will capture the vibrant momentum and pivotal juncture of this rapidly evolving field.

We invite high-quality contributions elucidating transformative breakthroughs across the perovskite PV spectrum. Topics of interest include novel material design and compositional engineering; innovative deposition techniques enhancing reproducibility and scalability; fundamental insights into crystallization kinetics, defect physics, charge carrier dynamics, and degradation mechanisms; advanced characterization methodologies; interface and contact engineering strategies; device architecture innovations (including flexible, tandem, and multi-junction configurations); strategies for enhancing intrinsic and operational stability under real-world stressors; computational modelling guiding material and device design; progress in lead-reduced and lead-free alternatives; and pathways towards commercialization and sustainability.

This Special Issue will provide a comprehensive platform for disseminating cutting-edge research, fostering critical discourse on persistent challenges, and charting the trajectory for next generation high-performance, stable, and manufacturable perovskite solar technologies. We welcome original research articles, reviews, and perspectives that push the boundaries of knowledge and application.

The performance of inverted CH3NH3GeI3 (MAGeI3) perovskite solar cells incorporating both a hole transport layer (HTL) and an electron transport layer (ETL) was investigated using the Solar Cell Capacitance Simulator (SCAPS). Three candidate HTLs, including PEDOT:PSS, MoS2, and WS2, along with five ETLs including PCBM, TiO2, IGZO, ZnO, and SnO2, have been systematically evaluated. The analysis shows that WS2 and SnO2 provided the most favorable hole and electron transport, respectively. To improve device efficiency, the absorber layer thickness, defect density in MAGeI3, doping levels of WS2 and SnO2, as well as the interface defect densities and the work function of indium tin oxide (ITO), have been systematically studied. The optimal absorber layer thickness is determined to be approximately 900 nm. The optimal doping density of both WS2 and SnO2 is 1 × 1019 cm−3. The MAGeI3 layer should maintain a defect density as low as 1 × 1015 cm−3, and the defect densities at MAGeI3 interfaces should remain at 1 × 1015 cm−2. Additionally, an ITO work function of at least 5.2 eV is necessary to prevent the formation of a Schottky barrier at the ITO/WS2 interface. The simulated power conversion efficiency (PCE) can reach 22.9% under these optimized conditions. Our simulation results offer a viable route to develop high-efficiency MAGeI3 perovskite solar cells.
