Problems solved by technology

[0007] The technical problem mainly solved by the present invention: Although the raw materials of common silicon-based solar photovoltaic panels are rich and non-toxic, their stability is low and they are easily affected by the environment. Reduce the output power of the entire battery panel, and its preparation process is complex and expensive, and a method for preparing a bismuth telluride nanocrystalline solar panel is provided. The method uses bismuth tellurium to smear conductive glass and put it into lettuce chlorophyll extract It can be prepared after soaking and adding electrolytes. The coating of tellurium bismuth nanocrystals gives full play to the characteristics of nanostructure materials, improves the stability of the battery board, and solves the defects of traditional battery boards that are easily affected by the environment and work unstable. At the same time, it also makes up for the shortcomings of its complex preparation process and high cost, and has a wide range of application prospects.

Abstract

The invention relates to a preparation method for a tellurium bismuth nano-crystalline solar cell panel, and belongs to the field of new energy resources. The tellurium bismuth nano-crystalline solar cell pane can be prepared by the steps of coating conductive glass with tellurium and bismuth, putting the coated conductive glass into lettuce chlorophyll extracting liquid to be socked, and adding an electrolyte. Due to the tellurium bismuth nano-crystalline coating, the characteristics of the nanostructure material are fully utilized; the stability of the battery panel is improved; the shortcoming that the conventional battery panel is influenced easily by the environment and is unstable in operation is overcame; the shortcomings of complicated preparation process and high cost are overcame also; and therefore, the preparation method for the tellurium bismuth nano-crystalline solar cell panel is wide in application prospects.

Description

technical field [0001] The invention relates to a preparation method of a bismuth tellurium nanocrystalline solar panel, which belongs to the field of new energy. Background technique [0002] In recent years, with the continuous increase of human society's demand for energy, the consumption of petrochemical energy is also increasing and facing the danger of depletion. Finding and large-scale development of sustainable, low-cost and environmentally friendly new energy sources has become a major issue in the current society. In nature, clean energy resources such as solar energy and geothermal energy are abundant. How to convert these energies into easily utilizable electric energy efficiently and at low cost has become a scientific issue that has attracted much attention in the energy field. [0003] Thermoelectric material is a functional material that realizes mutual conversion between thermal energy and electrical energy through the transport of carriers in solids, and i...
