Redox couples based on cobalt complexes were found to be effective in regenerating both inorganic CdSe quantum dot-and organic dye-sensitizers. The hybrid sensitizer composed of CdSe QD and ruthenium sensitizer (Z907Na) dye showed a maximum power conversio ...

Four spirobisacridine (SBA) hole-transporting materials were synthesized and employed in perovskite solar cells (PSCs). The molecules bear electronically inert alkyl chains of different length and bulkiness, attached to in-plane N atoms of nearly orthogona ...

A series of tri-tert-butyl zinc(II) phthalocyanines (Pcs) substituted with pyridyl, carboxyl, or picolinic acid anchoring groups on the periphery were prepared. Photovoltaic (PV) studies on these dyes were carried out revealing some interesting features. I ...

Organolead iodide perovskite, CH3NH3PbI3, was prepared in the form of nanowire by means of a small quantity of aprotic solvent in two-step spin-coating procedure. One-dimensional nanowire perovskite with the mean diameter of 100 nm showed faster carrier se ...

The effect of chenodeoxycholic acid as the coadsorbent with a squaraine sensitizer on TiO2 nanocrystalline solar cells was investigated, and it was found that the coadsorbent prevents the squaraine sensitizer from aggregating on the TiO2 nanoparticles but ...

Organohalide lead perovskites have revolutionized the scenario of emerging photovoltaic technologies. The prototype MAPbI(3) perovskite (MA = CH3NH3+) has dominated the field, despite only harvesting photons above 750 nm (similar to 1.6 eV). Intensive rese ...

Thermal vacuum deposition is a stimulating technique for upscaling perovskite solar cells. However, the operational complexity of multisource vapor deposition (MSVD) and achieving stoichiometric perovskite layers may impede its implementation. The single-s ...

All-inorganic CsPbI3 perovskite solar cells (PSCs) with efficiencies exceeding 20% are ideal candidates for appli-cation in large-scale tandem solar cells. However, there are still two major obstacles hindering their scale-up: (i) the inhomogeneous solid-s ...

Herein, we present the first use of a gallium oxide tunnelling layer to significantly reduce electron recombination in dye-sensitized solar cells (DSC). The sub-nanometer coating is achieved using atomic layer deposition (ALD) and leading to a new DSC reco ...

A new type of hole transporting material (HTMs) with an incorporated planar amine or triphenylamine as a core unit have been prepared. The two amine derivatives were demonstrated to be efficient hole transporting materials in fabricating solid-state organi ...

Dye-sensitized solar cells have gained widespread attention in recent years because of their low production costs, ease of fabrication and tunable optical properties, such as colour and transparency. Here, we report a molecularly engineered porphyrin dye, ...

Isomerization of a neutral bis-cyclometalated iridium(III) complex has been observed for the first time during the preparation of vacuum-processed organic light-emitting devices (OLEDs) and reproduced in solution. Isolation of the isomer revealed a cis org ...

Two novel symmetrical blue squaraine sensitizers were synthesized, which exhibit panchromatic light harvesting and a record efficiency over 6% with J(sc) exceeding 14 mA cm(-2), and V-oc over 620 mV under 1 sun. Their color, low cost, easiness of synthesis ...

We report all solid-state nanostructured inorganic-organic heterojuncuon solar cells fabricated by depositing Sb2S3 and poly(3-hexylthiophene) (P3HT) on the surface of a mesoporous TiO2 layer, where Sb2S3 acts as an absorbing semiconductor and P3HT acts as ...

Atomistic‐level understanding of electrocatalytic mechanism is pivotal to developing amorphous/crystalline heterostructures for highly efficient overall water splitting (OWS). Herein, an amorphous‐crystalline Ni3S2/Cu heterojunction (a‐Ni3S2/Cu) is constru ...

The black phase of formamidinium lead iodide (FAPbI(3)) perovskite shows huge promise as an efficient photovoltaic, but it is not favoured energetically at room temperature, meaning that the undesirable yellow phases are always present alongside it during ...

One-dimensional microrods (4-5 mm) of PbI2 and CH3NH3PbI3 (MAPbI(3)) with unique structural and morphological properties have been grown at room temperature. X-ray diffraction (XRD) patterns of both types of micro-rods exhibit a hexagonal system (P3m1(164) ...

Perovskite solar modules have been attracting increasing attention due to their market potential, yet publications concerned with theintrinsic scale-up potential of different perovskite compositions remain relatively scarce. On the other hand, while great ...

The present invention provides novel dyes for dye sensitized photovoltaic conversion devices. The dyes contain novel anchoring ligands, which have a vinyl or phenylethenyl moiety incorporated in the anchoring bipyridine. Such dyes exhibit an increased mola ...
