Problems solved by technology

However, this process is expensive and complicated, and it is easy to damage the perovskite film
[0005] The translucent cells prepared by the above technology have common disadvantages: none of them can achieve full-spectrum transmission and cannot achieve good transmittance

Abstract

The invention discloses a semitransparent hollow perovskite solar cell and a preparation method thereof. The cell is a positive cell structure or an inverted cell structure, the positive cell structure sequentially comprises a transparent glass layer, a bottom electrode layer, an electron transport layer, a perovskite layer, a hole transport layer and a top electrode layer from bottom to top, andthe inverted cell structure sequentially comprises a transparent glass layer, a bottom electrode layer, a hole transport layer, a perovskite layer, an electron transport layer and a top electrode layer from bottom to top. The cell is provided with a plurality of semi-hollow holes, and the semi-hollow holes at least penetrate through the top electrode layer, the hole transport layer and the perovskite layer of the positive cell structure, or penetrate through the top electrode layer, the electron transport layer and the perovskite layer of the inverted cell structure. The preparation method canbe used for preparing the full-spectrum semitransparent perovskite solar cell and can be used for simply, conveniently and efficiently manufacturing the full-spectrum semitransparent perovskite solarcell.

Description

technical field [0001] The invention belongs to the technical field of perovskite solar cells, in particular to a translucent hollow perovskite solar cell and a preparation method thereof. Background technique [0002] In the past ten years, the efficiency of perovskite solar cells has risen rapidly from 9.3% to 25.5%, showing great application potential in photovoltaic building integration, module devices, photovoltaic vehicles and other application fields. To meet such demands, translucent or fully transparent perovskite solar cells have been developed. [0003] At present, there are mainly two technical solutions for realizing semi-transparent perovskite solar cells. One is to reduce the concentration of the perovskite precursor and prepare a thinner perovskite film to obtain a translucent effect. The disadvantage of this process is that the thinning of the perovskite layer leads to more defects, more pinholes, and poorer film quality, which in turn affects the efficien...
