  • Patent number: 12218263
    Abstract: Method of manufacturing a single-side-contacted photovoltaic device (1), comprising the steps of: a) providing a photovoltaically-active substrate (3) defining a plurality of alternating hole collecting zones (3a) and electron collecting zones (3b) arranged in parallel strips; b) depositing a conductive layer (5) across said zones; c) depositing at least one conductive track (9) extending along at least part of each of said zones (3a, 3b); d) selectively forming a dielectric layer (7) on each of said zones (3a, 3b), so as to leave an exposed area free of dielectric at an interface between adjacent zones (3a, 3b); e) etching said conductive layer (5) in said exposed areas; f) applying a plurality of interconnecting conductors (11a, 11b) so as to electrically interconnect at least a portion of said hole collecting zones (3a) with each other, and to electrically interconnect at least a portion of said electron collecting zones (3b) with each other.

  • Publication number: 20240301558
    Abstract: A solution including at least one metal salt, a reducing agent which makes it possible to reduce the metal salt, and a stabilising additive of formula F1 in which the Ra, Rb and Rc groups denote, independently of one another, an alkane, an alkene or an alkyne, which may be independently linear, branched or cyclic and which include from 1 to 20 carbon atoms, and where the Rd and Re groups denote, independently of one another, a hydrogen atom, or an alkane, an alkene or an alkyne, which may each be independently linear, branched or cyclic and which include from 1 to 20 carbon atoms.

  • Publication number: 20240251573
    Abstract: A method of manufacturing an optoelectronic device includes the steps of: providing a substrate; depositing a first electrode layer on the substrate; depositing a first charge-carrier selective layer with a thickness less than 5 nm situated directly on the first electrode layer; depositing insulating silicon oxide nanoparticles directly on the first charge-carrier selective layer, the particles having a diameter between 10 nm and 100 nm; depositing a perovskite-based semiconductor layer on the first charge-carrier selective layer and on the insulating silicon oxide nanoparticles, the perovskite-based semiconductor layer being in intimate contact with both the first charge-carrier selective layer and the insulating silicon oxide nanoparticles; depositing a second charge-carrier selective layer on the perovskite-based semiconductor layer; depositing a second electrode layer on the second charge-carrier selective layer.
