Perovskite Quantum Dots in Solar Cells

Perovskite quantum dots (PQDs) have captured a host of researchers'' attention due to their unique properties, which have been introduced to lots of optoelectronics areas, such as light-emitting diodes, lasers, photodetectors, and solar cells. Herein, the authors aim ...

Interface engineering of highly efficient perovskite …

Advancing perovskite solar cell technologies toward their theoretical power conversion efficiency (PCE) requires delicate control over the carrier dynamics throughout the entire device. By controlling the …

Bimolecularly passivated interface enables efficient and stable inverted perovskite solar cells | Science

Compared with the n-i-p structure, inverted (p-i-n) perovskite solar cells (PSCs) promise increased operating stability, but these photovoltaic cells often exhibit lower power conversion efficienci... Diammonium ligands, in which one -NH 3 + group anchors to the perovskite surface and the other extends away from it, can induce a surface dipole …

Efficient tandem solar cells with solution-processed …

Through an intensive worldwide effort, perovskite solar cell (PSC) power conversion efficiencies (PCEs) have increased from an initial 3.8% to a certified 25.2% during the past decade (1, 2).This progress is …

Vapor-assisted deposition of highly efficient, stable black-phase FAPbI3 perovskite solar cells | Science

The bandgap of the black α-phase FAPbI 3 (where FA is formamidinium) is nearly ideal for solar cells, but it is unstable with respect to the photoinactive yellow δ-phase. Lu et al. found that a film of the yellow phase was converted to a highly crystalline black phase by vapor exposure to methylammonium thiocyanate at 100 C, and it retained …

Resolving spatial and energetic distributions of trap states in metal halide perovskite solar cells

We report the profiling of spatial and energetic distributions of trap states in metal halide perovskite single-crystalline and polycrystalline solar cells. The trap densities in single crystals varied by five orders of magnitude, with a lowest value of 2 × 10 11 per cubic centimeter and most of the deep traps located at crystal surfaces.

Metastable Dion-Jacobson 2D structure enables efficient and stable perovskite solar cells | Science

Perovskite solar cells (PSCs) are a promising photovoltaic (PV) technology, and certified power conversion efficiencies (PCEs) as high as 25.5% have been reported () spite this high performance, device stability hinders their commercialization. Efforts to improve ...

Conformal quantum dot–SnO2 layers as electron transporters for efficient perovskite solar cells | Science

Mesoporous titanium dioxide is commonly used as the electron transport layer in perovskite solar cells, but electron transport layers based on tin(IV) oxide quantum dots could be more efficient, with a better-aligned conduction band and a higher carrier mobility. Kim et al. show that such quantum dots could conformally coat a textured …

OverviewHistoryApplicationsDeclining costs and exponential growthTheoryEfficiencyMaterialsResearch in solar cells

The photovoltaic effect was experimentally demonstrated first by French physicist Edmond Becquerel. In 1839, at age 19, he built the world''s first photovoltaic cell in his father''s laboratory. Willoughby Smith first described the "Effect of Light on Selenium during the passage of an Electric Current" in a 20 February 1873 issue of Nature. In 1883 Charles Fritts built the first solid state photovoltaic cell by coati…

Unveiling facet-dependent degradation and facet engineering for stable perovskite solar cells

Stability is one of the most pressing issues that hinders the commercialization of perovskite solar cells (PSCs), despite efficiencies greater than 25% (1–3).The degradation of hybrid perovskite thin films by moisture, thermal stress, and light is a complex process ...

Challenges for commercializing perovskite solar cells | Science

Perovskite solar cells (PSCs) have attracted intensive attention because of their ever-increasing power conversion effi ciency (PCE), low-cost materials constituents, and simple solution fabrication process. Initi ated in …

Nanoscale localized contacts for high fill factors in polymer-passivated perovskite solar cells

The rise in perovskite solar cell (PSC) performance has been marked by substantial increases in open-circuit voltage (V oc), short-circuit current (J sc), and fill factor (FF), as illustrated in Fig. 1 for reported values since 2014 (1–9).The steady increase in V oc from ~1 to ~1.2 V (for simplicity, we ignore bandgap differences between the record cells) …

Interfacial toughening with self-assembled monolayers enhances perovskite solar cell reliability

The low formation energies of the active layers in perovskite solar cells lead to low-toughness materials that are compliant and soft, which limits their interface stability and long-term reliability. Dai et al. show that treatment with iodine-terminated self-assembled monolayers that react with surface hydroxyl groups (which ultimately creates unwanted …
