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： The invention relates to a perovskite tandem solar cell based on a tunneling layer of two-dimensional layered metal carbides and metal nitrides, the tunneling junction composite layer is prepared by using two-dimensional layered metal carbides and metal nitrides, a dense layer is arranged on one side of the tunneling junction composite layer, and a transport layer is arranged on the other side. The two-dimensional layered metal carbide and metal nitride materials are selected from graphene, Ti3C2Tx, Mo2CTx, V2CTx, Nb2CTx and Ti2CTx. The tunneling junction structure of the invention can effectively reduce the light loss in the tandem solar cell and the interface recombination of the tandem cell, which can significantly improve the photocurrent generation and charge transfer of the perovskite/perovskite tandem solar cell, and improve the power conversion efficiency of the perovskite/perovskite tandem solar cell.

摘要： Provided are a phenanthroline-based compound, a method of preparing the same, and a perovskite solar cell including the same. The phenanthroline-based compound may be formed as a uniform layer even by a solution process due to its low average surface roughness (root mean square, RMS) and excellent processability. When a layer having the phenanthroline-based compound is provided as a polymer functional layer of the perovskite solar cell, the ionic defects on the surface between the perovskite and a metal oxide, may be passivated and charge transfer may be facilitated so that the energy efficiency and photostability of the solar cell are improved.
