Advanced Materials, Год журнала: 2022, Номер 34(44)

Опубликована: Июнь 30, 2022

Abstract Hole‐transporting layers (HTLs) are an essential component in inverted, p–i–n perovskite solar cells (PSCs) where they play a decisive role extraction and transport of holes, surface passivation, crystallization, device stability, cost. Currently, the exploration efficient, stable, highly transparent low‐cost HTLs is vital importance for propelling PSCs toward commercialization. Compared to their inorganic counterparts, organic offer multiple advantages such as tunable bandgap energy level, easy synthesis purification, solution processability, overall low Here, recent progress HTLs, including conductive polymers, small molecules, self‐assembled monolayers, utilized inverted systematically reviewed summarized. Their molecular structure, hole‐transport properties, levels, relevant properties resulting performances presented analyzed. A summary design principles future outlook efficient proposed. This review aims inspire further innovative development novel more scalable PSCs.

Recent progress in the development of high-efficiency inverted perovskite solar cells

NPG Asia Materials, Год журнала: 2023, Номер 15(1)

Опубликована: Май 5, 2023

Abstract Perovskite solar cells (PSCs) have attracted much attention due to their low-cost fabrication and high power conversion efficiency (PCE). However, the long-term stability issues of PSCs remain a significant bottleneck impeding commercialization. Inverted with p-i-n architecture are being actively researched concurrent good decent efficiency. In particular, PCE inverted has improved significantly in recent years is now almost approaching that n-i-p PSCs. This review summarizes progress development high-efficiency PSCs, including perovskite compositions, methods, counter electrode materials (CEMs). Notably, we highlight charge transport (CTMs) effects defect passivation strategies on performance Finally, discuss remaining perspectives

Lead-chelating hole-transport layers for efficient and stable perovskite minimodules

Science, Год журнала: 2023, Номер 380(6647), С. 823 - 829

Опубликована: Май 25, 2023

The defective bottom interfaces of perovskites and hole-transport layers (HTLs) limit the performance p-i-n structure perovskite solar cells. We report that addition lead chelation molecules into HTLs can strongly interact with lead(II) ion (Pb 2+ ), resulting in a reduced amorphous region near passivated surface. minimodule an aperture area 26.9 square centimeters has power conversion efficiency (PCE) 21.8% (stabilized at 21.1%) is certified by National Renewable Energy Laboratory (NREL), which corresponds to minimal small-cell 24.6% 24.1%) throughout module area. Small-area cells large-area minimodules had light soaking stability 3010 2130 hours, respectively, loss 10% from initial value under 1-sun illumination open-circuit voltage conditions.

Reinforcing self-assembly of hole transport molecules for stable inverted perovskite solar cells

Science, Год журнала: 2024, Номер 383(6688), С. 1236 - 1240

Опубликована: Март 14, 2024

Power conversion efficiencies (PCEs) of inverted perovskite solar cells (PSCs) have been improved by the use a self-assembled monolayer (SAM) hole transport layer. Long-term stability PSCs requires keeping SAM compact under layer during operation. We found that strong polar solvents in precursor desorb if it is anchored on substrates hydrogen-bonded, rather than covalently bonded, hydroxyl groups. used atomic-layer deposition to create an indium tin oxide substrate with fully covalent hydroxyl-covered surface for anchoring, as well trimethoxysilane group exhibited tridentate anchoring substrate. The resulting achieved PCEs 24.8 (certified 24.6) and 23.2% aperture areas 0.08 1.01 square centimeters, respectively. devices retained 98.9 98.2% initial PCE after 1000 hours damp-heat test operation maximum power point tracking at 85°C 1200 standard illumination,
