Abstract The main obstacles to promoting the commercialization of perovskite solar cells (PSCs) include their record power conversion efficiency (PCE), which still remains below Shockley–Queisser limit, and poor long‐term stability, attributable crystallographic defects in films open‐circuit voltage ( V oc ) loss devices. In this study, potassium (4‐tert‐butoxycarbonylpiperazin‐1‐yl) methyl trifluoroborate (PTFBK) was employed as a multifunctional additive target modulate bulk carrier dynamics PSCs. Apart from simultaneously passivating anionic cationic defects, PTFBK could also optimize energy‐level alignment devices weaken interaction between carriers longitudinal optical phonons, resulting lifetime greater than 3 μs. Furthermore, it inhibited non‐radiative recombination improved crystallization capacity film. Hence, rigid flexible p‐i‐n PSCs yielded champion PCEs 24.99 % 23.48 %, respectively. More importantly, due hydrogen bonding formamidinium fluorine, exhibited remarkable thermal, humidity, operational tracking at maximum point stabilities. reduced Young's modulus residual stress layer provided excellent bending stability for

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.

Compared with the n-i-p structure, inverted (p-i-n) perovskite solar cells (PSCs) promise increased operating stability, but these photovoltaic often exhibit lower power conversion efficiencies (PCEs) because of nonradiative recombination losses, particularly at perovskite/C60 interface. We passivated surface defects and enabled reflection minority carriers from interface into bulk using two types functional molecules. used sulfur-modified methylthio molecules to passivate suppress through strong coordination hydrogen bonding, along diammonium repel reduce contact-induced achieved field-effect passivation. This approach led a fivefold longer carrier lifetime one-third photoluminescence quantum yield loss certified quasi-steady-state PCE 25.1% for PSCs stable operation 65°C >2000 hours in ambient air. also fabricated monolithic all-perovskite tandem 28.1% PCE.

The power conversion efficiency (PCE) of inverted perovskite solar cells (PSCs) is still lagging behind that conventional PSCs, in part because inefficient carrier transport and poor morphology hole layers (HTLs).

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.
