Abstract

The invention belongs to the technical field of solar cell application, in particular relates to an organic solar traffic light comprising a signal light, a solar cell, a storage cell and a control unit, wherein the solar cell is connected with the signal light; the storage cell is connected between the solar cell and the signal light; the signal light is formed by an OLED (Organic Light-Emitting Diode) array; an active layer of the solar cell is formed by stacking organic materials CuPo / C60; an ultrathin Au layer (0.5+ / -0.2nm) is modified on a ZnO:Al anode, and therefore, compared with the energy conversion efficiency of a solar cell without an Au modifying layer, the energy conversion efficiency of the organic solar cell is increased by about 10 times. The organic solar traffic light has low cost and convenient and simple facilities and is especially suitable for a crossing without an alternating current area. In addition, the organic solar traffic light can work by directly using solar energy to supply electric energy in a sunny day and stores electric energy into the storage cell and can also work by using the electric energy stored in the storage cell at night or an overcast and rainy day, thus the organic solar traffic light can work uninterruptedly throughout the year.

Description

technical field [0001] The invention belongs to the technical field of solar energy application, in particular to an organic solar traffic signal lamp. Background technique [0002] Traffic lights at traditional intersections are powered by alternating current, which is difficult to maintain, requires high cost of laying wires, and has poor flexibility. [0003] People have put forward research on using solar energy as a new energy source for power supply, but most of the applications are photovoltaic panels made of inorganic materials such as silicon, which have been used to a certain extent, but due to cost constraints, the application is not very extensive. [0004] In recent years, the application of organic materials in the field of solar energy has been continuously developed, mainly considering the advantages of low price, simple preparation process, and large-area production. But there are still few reports about organic solar traffic lights. The invention effectiv...
