Abstract Organic–inorganic hybrid perovskite solar cells (PSCs) have seen a rapid rise in power conversion efficiencies recent years; however, they still suffer from interfacial recombination and charge extraction losses at interfaces between the absorber charge–transport layers. Here, situ back‐contact passivation (BCP) that reduces hole transport layer (HTL) is reported. A thin of nondoped semiconducting polymer perovskite/HTL interface introduced it shown use semiconductor permits—in...
Abstract Perovskite solar cells (PSCs) have witnessed rapid development toward commercialization based on their superior efficiency except for some remained misgivings about poor stability primarily originating from interfacial problems. Robust back interface neutralization of crystal defects, depression dopant lithium ions (Li + ) diffusion, and even inhibition toxic lead (Pb) leakage is highly desirable; however, it remains a great challenge. Herein, cost‐effective therapy approach...
Recent developments of quinoxaline-based conjugated polymers for polymer solar cells are reviewed.
Charge carrier events across organic electronics are ubiquitous, and the derived optimization plays a crucial effect on improving performance of electronics. Herein, two-dimensional material (Ti3C2Tx) is incorporated into titanium dioxide (TiO2) to impart Ti3C2Tx/TiO2 hybrid film enriched hydroxy group distribution, defect-negligible surface, upshifted work function, enhanced conductivity yet electron mobility versus pristine TiO2 film. Therefore, intensified photon-harvesting ability,...
Abstract Organic solar cells (OSCs) exhibit complex charge dynamics, which are closely correlated with the dielectric constant (ɛ r ) of photovoltaic materials. In this work, a series novel conjugated copolymers based on benzo[1,2‐b:4,5‐b′]difuran (BDF) and benzotriazole (BTz) is designed synthesized, differ by nature π‐bridge from one another. The PBDF‐TF‐BTz asymmetric furan thiophene demonstrates larger ɛ 4.22 than PBDF‐dT‐BTz symmetric (3.15) PBDF‐dF‐BTz (3.90). also offers more...
Dye-sensitized solar cells (DSSCs) based on the TiO2 photoanode are promising contenders for photovoltaic technology. However, shows severe charge recombination and leads to rapid photodegradation of absorbed dyes due its photocatalytic activity. Herein, we developed a hybrid by embedding multifunctional fulleropyrrolidine (PCBO-3) into film. The film presents higher electron mobility, aligned energy level with dyes, reduced oxygen vacancy defects, synergistically contributing suppressed...
Carbon-based perovskite solar cells (PSCs) coupled with solution-processed hole transport layers (HTLs) have shown potential owing to their combination of low cost and high performance. However, the commonly used poly(3-hexylthiophene) (P3HT) semicrystalline-polymer HTL dominantly shows edge-on molecular orientation, in which alkyl side chains directly contact layer, resulting an electronically poor at perovskite/P3HT interface. The study adopts a synergetic strategy comprising additive...
Fused-ring electron donors boost the efficiency of organic solar cells (OSCs), but they suffer from high cost and low yield for their large synthetic complexity (SC > 30%). Herein, authors develop a series simple non-fused-ring donors, PF1 PF2, which alternately consist furan-3-carboxylate 2,2'-bithiophene. Note that PF2 present very small SC 9.7% inexpensive raw materials, facile synthesis, yield. Compared to all-thiophene-backbone counterpart PT-E, two new polymers feature larger...
Hole transport layers (HTLs) in perovskite photovoltaics do not just play a key role device performance; they also determine the overall flexibility, cost, and opportune tandem solar cell applications. Currently used HTLs have limited functionality are costly. Here, we develop an efficient bifunctional cost-effective HTL based on electrochemically deposited polyaniline (PAN) decorated with dodecyl benzene sulfonic acid. We then resurface PAN chlorine to improve conductivity provide...
Among all‐inorganic perovskite photoactive materials, CsPbIBr 2 demonstrates the most balanced trade‐off between optical bandgap and phase stability. However, poor quality high‐temperature engineering of film hinder further optimization derived solar cells (PSCs). Herein, a simple dynamic vacuum‐assisted low‐temperature (merely 140 °C) is proposed to prepare high‐quality (VALT‐CsPbIBr film). Compared HT‐CsPbIBr processed via conventionally high temperature (280 °C), VALT‐CsPbIBr presents...
Carbon electrode perovskite solar cell has great potential in commercial application based on its low cost, superior stability, and facile fabrication process. However, performance still lags behind that of devices with gold anode, which greatly attributes to the insufficient charge transport collection at carbon anode side. Herein, efficient buffer contact is built by constructing an organic/inorganic composite hole bilayer together strategic precovering/postcovering anode. Adding a...
Abstract Perovskite solar cells (PSCs) have witnessed a meteoric rise in device performance. However, maintaining photostability, particularly under thermal stress, remains challenge due to defect formation the perovskite layer. This study introduces europium (III) trifluoromethanesulfonate [Eu(OTF) 3 ] as multifunctional additive two‐step processed films, significantly improving performance and high‐temperature photostability of n‐i‐p PSCs. Density function theory (DFT) calculations reveal...
