Abstract

The invention discloses a perovskite solar cell with zinc telluride serving as a hole transporting layer and a manufacturing method thereof. The perovskite solar cell is characterized in that the perovskite solar cell comprises a transparent conductive electrode, an electron transporting layer, a perovskite structure light absorbing layer, the zinc telluride hole transporting layer and a positive electrode. Due to the fact that the zinc telluride is adopted to serve as the hole transporting layer, the perovskite solar cell has the advantages that the stability of the perovskite solar cell can be improved, the service life of the perovskite solar cell can be prolonged and the manufacturing cost can be lowered.

Description

Technical field [0001] The invention belongs to the field of solar cells, and particularly relates to a perovskite solar cell using zinc telluride as a hole transport layer and a preparation method thereof. Background technique [0002] With the consumption of traditional energy, the energy crisis and environmental problems have become serious problems facing the world. Green, safe, and inexhaustible solar power makes photovoltaic power generation an ideal solution to human energy crisis and environmental pollution. High photoelectric conversion efficiency and low manufacturing cost are prerequisites for popularizing photovoltaic power generation. Therefore, solar cells with both high efficiency and low cost are the goals that people are constantly pursuing in the energy field. [0003] In the current practical application of solar energy, silicon photovoltaic cells dominate various photovoltaic devices with their mature technology and high photoelectric conversion efficiency.
