Embodiment 1

[0019] A method for embedding a P-type nano material in a carbon electrode to enhance a perovskite solar cell without a hole transport layer, the specific steps include:

[0020] Step 1. Prepare TiO on FTO glass with titanate as the precursor 2 Dense layer, followed by TiO 2 Nano slurry, annealing to produce TiO 2 Mesoporous film, then in TiO 2 Perovskite film deposited on the surface of mesoporous film, such as CH 3 NH 3 PbI 3 film.

[0021] Step 2, mixing P-type nano-material NiO nanoparticles in the carbon slurry. The P-type nanomaterials mixed in the carbon slurry can be mixed during the preparation of the carbon slurry or can be mixed in the prepared carbon slurry.

[0022] Step 3, coating the carbon slurry mixed with P-type nano-material NiO nanoparticles on the surface of the perovskite, annealing at low temperature to form a back electrode, and completing the preparation of the perovskite solar cell.

[0023] Among them, the carbon slurry is mixed with P-type nanomaterials, th...

Abstract

The invention provides a perovskite solar cell embedding a P-type nano material into a carbon electrode, and a preparation method thereof. Through directly embedding the P-type nano material into a carbon slurry, the performance of the perovskite solar cell is enhanced, and the realization of the perovskite solar cell with high stability, low cost and high performance is of great significance to promote the commercialization of perovskite solar cells.

Description

Technical field [0001] The invention belongs to the technical field of perovskite solar cells, and specifically relates to a perovskite solar cell with a P-type nano material embedded in a carbon electrode to enhance a hole-free transport layer and a preparation method thereof. Background technique [0002] Perovskite solar cells have been a hot spot in recent years. The device efficiency has risen to more than 22% and is a star in the photovoltaic field. At present, the common hole transport material for perovskite solar cells is expensive spiro-MeOTAD, and the additives in it will reduce the stability of the device. Due to the dual characteristics of perovskite-electrons and holes can be transported, perovskite solar cells without a hole transport layer have been proposed. Among them, the perovskite solar cell with no hole transport layer on the carbon electrode has obvious advantages, which not only greatly reduces the process and cost of the perovskite solar cell, but also ...
