Stabilized hole-selective layer for high-performance inverted p-i-n perovskite solar cells

Science, Год журнала: 2023, Номер 382(6668), С. 284 - 289

Опубликована: Окт. 19, 2023

P-i-n geometry perovskite solar cells (PSCs) offer simplified fabrication, greater amenability to charge extraction layers, and low-temperature processing over n-i-p counterparts. Self-assembled monolayers (SAMs) can enhance the performance of p-i-n PSCs but ultrathin SAMs be thermally unstable. We report a robust hole-selective layer comprised nickel oxide (NiOx) nanoparticle film with surface-anchored (4-(3,11-dimethoxy-7H-dibenzo[c,g]carbazol-7-yl)butyl)phosphonic acid (MeO-4PADBC) SAM that improve stabilize NiOx/perovskite interface. The energetic alignment favorable contact binding between NiOx/MeO-4PADBC reduced voltage deficit various compositions led strong interface toughening effects under thermal stress. resulting 1.53-electron-volt devices achieved 25.6% certified power conversion efficiency maintained >90% their initial after continuously operating at 65 degrees Celsius for 1200 hours 1-sun illumination.

Engineering ligand reactivity enables high-temperature operation of stable perovskite solar cells

Science, Год журнала: 2023, Номер 381(6654), С. 209 - 215

Опубликована: Июль 13, 2023

Perovskite solar cells (PSCs) consisting of interfacial two- and three-dimensional heterostructures that incorporate ammonium ligand intercalation have enabled rapid progress toward the goal uniting performance with stability. However, as field continues to seek ever-higher durability, additional tools avoid progressive are needed minimize degradation at high temperatures. We used ligands nonreactive bulk perovskites investigated a library varies molecular structure systematically. found fluorinated aniliniums offer passivation simultaneously reactivity perovskites. Using this approach, we report certified quasi-steady-state power-conversion efficiency 24.09% for inverted-structure PSCs. In an encapsulated device operating 85°C 50% relative humidity, document 1560-hour T85 maximum power point under 1-sun illumination.

Pathways toward commercial perovskite/silicon tandem photovoltaics

Science, Год журнала: 2024, Номер 383(6679)

Опубликована: Янв. 11, 2024

Perovskite/silicon tandem solar cells offer a promising route to increase the power conversion efficiency of crystalline silicon (c-Si) beyond theoretical single-junction limitations at an affordable cost. In past decade, progress has been made toward fabrication highly efficient laboratory-scale tandems through range vacuum- and solution-based perovskite processing technologies onto various types c-Si bottom cells. However, become commercial reality, transition from laboratory industrial will require appropriate, scalable input materials manufacturing processes. addition, perovskite/silicon research needs increasingly focus on stability, reliability, throughput cell production characterization, cell-to-module integration, accurate field-performance prediction evaluation. This Review discusses these aspects in view contemporary manufacturing, offers insights into possible pathways photovoltaics, highlights opportunities realize this goal.
