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.

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.

Abstract Perovskite solar cells have reached a power conversion efficiency over 25%, and the engineering of interface between perovskite hole transport layer (HTL) has been crucial to achieve high performance. Here we design bifunctional molecule CBz-PAI with carbazole-triphenylamine phenylammonium iodide units passivate defects at perovskite/HTL interface. Owing favourable energy level alignment perovskite, acts as shuttle HTL. This minimizes difference quasi-Fermi splitting or ‘internal’ V oc , external device thus reducing voltage losses. As result, incorporating reach stabilized 24.7% maintain 92.3% initial after 1,000 h under damp heat test (85 °C 85% relative humidity) 94.6% 1,100 maximum point-tracking conditions.

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,

Three-dimensional (3D) organic-inorganic lead halide perovskites have emerged in the past few years as a promising material for low-cost, high-efficiency optoelectronic devices. Spurred by this recent interest, several subclasses of such two-dimensional (2D) begun to play significant role advancing fundamental understanding structural, chemical, and physical properties perovskites, which are technologically relevant. While chemistry these 2D materials is similar that 3D their layered structure with hybrid interface induces new emergent can significantly or sometimes subtly be important. Synergistic realized systems combine different exhibiting dimensionalities exploiting intrinsic compatibility. In many cases, weaknesses each alleviated heteroarchitectures. For example, 3D-2D demonstrate novel behavior neither would capable separately. This review describes how structural differences between give rise disparate properties, discusses strategies realizing mixed-dimensional various architectures through solution-processing techniques, presents comprehensive outlook use solar cells.
