Abstract

The invention belongs to the field of photovoltaics, and particularly relates to a solar cell device taking a two-dimensional perovskite material as a light absorption layer and a preparation method thereof. The solar cell sequentially comprises a conductive glass layer, a compact electron transport layer, a perovskite light absorption layer, a hole transport layer and an electrode layer from bottom to top. According to the invention, a simple one-step spin-coating method is adopted, and the perovskite light absorption layer in the device is subjected to component regulation and control, so that the efficient solar cell is obtained. According to the invention, through simple component regulation and control, the key problem that the carrier transport of the two-dimensional perovskite material is limited is effectively solved, and the problem that the photoelectric conversion performance of a quasi-two-dimensional perovskite solar cell is generally relatively low is solved at the same time.

Description

technical field [0001] The invention belongs to the field of photovoltaics, and in particular relates to a solar cell device with a two-dimensional perovskite material as a light-absorbing layer and a preparation method thereof. Background technique [0002] Three-dimensional organometal halide perovskite solar cells have achieved tremendous development in the past few years. The power conversion efficiency (PCE) of the device has risen rapidly, and the highest efficiency has exceeded 25%, largely surpassing organic photoelectricity, dye-sensitized solar cells, and even comparable to silicon thin-film cells. Despite the great success of 3D perovskites, they also face some problems, such as inherent instability under light, heat and humidity, which prevent the batteries from realizing a wide range of applications. These instabilities are mainly derived from the high hydrophilicity of organic cations and the weak interaction between cations and halide ions. [0003] It has r...
