Embodiment 1

[0022] Will use polishing liquid (V (deionized water): V (HNO 3 ): V(HF)=5:4:1) The pretreated Ti wire is used as the anode, and the graphite sheet is used as the cathode, and the voltage is controlled by a DC stabilized power supply to 60V, containing 0.6wt% NH 4 F and 3.5v% H 2 The 150ml ethylene glycol solution of O is used as the electrolyte, anodized at room temperature and under magnetic stirring for 1 hour, and a layer of TiO can be coated on the surface of the Ti wire. 2 nanotube film. The anodized Ti wire (0.2-0.4 mm) was heat-treated at 450°C for 2 hours. After cooling to room temperature, with 0.2M TiCl 4 Treat in a water bath at 60°C for 1 hour, then heat-treat at 450°C for 30 minutes, cool naturally to 80°C, and put in 0.5 mM N719 dye solution in absolute ethanol to sensitize overnight to obtain sensitized TiO 2 nanotube film.

Abstract

The invention in particular provides a pine-tree solar cell landscape tree, which belongs to the field of solar photovoltaic. The pine-tree solar cell landscape tree comprises a trunk, branches and leaves, wherein the trunk, the branches and the leaves are sealed by high molecular rubbers and connected with each other by reserved ports; the trunk is a copper wire coated by hard plastic; the branches are copper wires coated by soft plastics; the leaves are dye-sensitized solar cells packaged by transparent glass tubes or plastic tubes; the cells are connected with each other in parallel; and the dye-sensitized solar cells among different branches are connected with each other in parallel. The pine-tree solar cell landscape tree provided by the invention can be used for collecting lights from each spatial direction, so that the sunlight utilization efficiency is increased; a defect of larger space usage of a flat-plate solar cell in the large-area application process is overcome; a making process is simple; meanwhile, the solar cell tree can be used as landscape trees for beautifying environments outdoors.

Description

technical field [0001] The invention belongs to the field of solar photovoltaics, and in particular relates to a pine-shaped solar cell landscape tree. Background technique [0002] Solar energy is the most active field in the development and utilization of new energy sources. One of the important ways to utilize solar energy is to develop solar cells. Traditional solar cells (including silicon solar cells, thin film solar cells, organic solar cells and dye-sensitized solar cells) generally adopt a planar structure. Although scientists have been working to improve the efficiency of flat solar cells, flat solar cells have their own insurmountable Disadvantages, such as not being able to be used in a small space, occupying a large area; strong dependence on the incident angle of solar energy, low utilization rate of sunlight, etc. Therefore, in order to make full use of clean solar energy to alleviate the energy crisis, how to solve the large area and use space of solar cells...
