摘要:
A dye sensitized solar cell, wherein a compacting compound whose molecular structure comprises a terminal group, a hydrophobic part and an anchoring group is co-adsorbed together with the dye on the semi-conductive metal oxide layer of the photoanode, forming a dense mixed self-assembled monolayer.
摘要:
The present invention provides a method for depositing an organic-inorganic perovskite, the method comprising the step of depositing a perovskite precursor solution comprising one or more organic cation, wherein said precursor solution is preferably deposited by inkjet printing. The method is particularly useful in the manufacture of perovskite solar cells. For depositing the perovskite, a perovskite precursor solution or ink is preferably used, which comprises an organic cation carrying an anchoring group, such as 5-ammonium valeric acid. Surprisingly, the presence of the latter compound renders the precursor solutions stable and suitable for inkjet printing.

摘要:
The present invention provides a solid state heterojunction solar cell comprising a transparent conducting support layer, on which a nanostructured, surface-increasing scaffold structure is provided, wherein an organic-inorganic perovskite layer is provided on said scaffold structure, and wherein a counter electrode and/or metal layer is provided in electric contact with said perovskite layer. According to an embodiment, the solar cell lacks an electrolyte or any hole conducting material. The invention also relates to a solid state heterojunction and to a method of preparing the solar cell.
摘要:
The present invention provides an improved redox couple for electrochemical and optoelectronic devices. The redox couple is based on a complex of a first row transition metal, said complex containing at least one mono-, bi-, or tridentate ligand comprising a substituted or unsubstituted ring or ring system comprising a five-membered N-containing heteroring and/or a six-membered ring comprising at least two heteroatoms, at least one of which being a nitrogen atom, said five- or six-membered heteroring, respectively, comprising at least one double bond. The invention also relates to electrolytes and to the devices containing the complex, and to the use of the complex as a redox couple. The invention further provides electrochemical and/or optoelectronic devices comprising a first and a second electrode and, between said first and second electrode, a charge transport layer, said a charge transport layer comprising tetracyanoborate ([B(CN)4]−) and a cationic metal complex functioning as redox-couple.
