摘要： A method of stabilizing perovskite ink, comprising the steps of preparing a perovskite ink using one or more solvents and adding to the perovskite ink a sulfur or sulfur based compound that interacts with amine groups in the perovskite ink to inhibit amine-water proton exchange. A perovskite ink, comprising precursor salts dissolved in one or more solvents that when deposited as a thin film crystallize to form the perovskite structure with an ‘ABX3’ composition in which: ‘A’ is a monovalent cation being one or more of methylammonium (MA+) and formamidinium (FA+). ‘B’ is a divalent cation, and ‘X’ is a halogen being one or more of F—, I—, Br— and Cl—; an additive selected from the group consisting of sulfur and sulfur based compounds that interacts with amine groups in the perovskite ink to inhibit amine-water proton exchange.

摘要： A tandem solar cell and a photovoltaic assembly, The tandem solar cell includes: a top-layer perovskite sub-cell and a bottom-layer crystalline-silicon sub-cell, and an optical regulating layer provided between the top-layer perovskite sub-cell and the bottom-layer crystalline-silicon sub-cell. After the part of the target light rays that are not absorbed by the top-layer perovskite sub-cell have passed through the top-layer perovskite sub-cell, because the optical regulating layer can be used to reflect at least some of the target light rays back into the top-layer perovskite sub-cell, at least some of the target light rays can enter the top-layer perovskite sub-cell again to perform secondary absorption, which prevents that the target light rays within the short-wave wave band directly enter the bottom-layer crystalline-silicon sub-cell having a low utilization ratio of the target light rays within the short-wave wave band, thereby increasing the efficiency of the tandem solar cell.

摘要： A perovskite solar battery, including a transparent conductive glass substrate, a hole transport layer, a perovskite light-absorbing layer, an electron transport layer, and an electrode are described. The hole transport layer is a nickel oxide hole transport layer. Simple-substance nickel exists on a contact surface of the hole transport layer in contact with the perovskite light-absorbing layer. On the contact surface of the hole transport layer in contact with the perovskite light-absorbing layer, a ratio between simple-substance nickel and trivalent nickel is 85:15 to 99:1, optionally 90:10 to 99:1, and further optionally 95:5 to 99:1. This application further provides a method for preparing a perovskite solar battery.
