Problems solved by technology

[0004] Especially, when the triboelectric nanogenerator is mixed with solar cells, due to its internal resistance R TENG Much larger than the internal resistance R of the solar cell DSSC , if a simple series connection will cause the output impedance of the solar cell fabric DSSC to be too large, the current will be almost zero
At the same time, because the performance of the electrical signal output by the triboelectric nanogenerator is a high-voltage, low-current alternating current, the R DSSC much smaller than R TENG will cause I DSSC greater than I TENG , using the above parallel method, when the light energy and mechanical energy are collected at the same time, the TENG is short-circuited, which seriously weakens the performance output of the TENG used to collect mechanical energy

Abstract

The invention provides a method for simultaneous and integrated electric energy outputting by a solar cell fabric unit and a friction nano generator. The method comprises: the solar cell fabric unit is formed by direct intersected braiding or wound connection of photo-anodes having fiber structures and counter electrodes of the fiber structures; the friction nano generator is formed by two electrodes having different interfacial electron adsorption capacities, wherein one electrode is equipped with negative electricity and the other electrode is equipped with positive electricity after the two electrodes are in contact and then are separated; elements having unidirectional conduction characteristics are connected to the photo-anodes or counter electrodes of the solar cell fabric unit and then parallel connection with the two electrodes of the friction nano generator is realized, thereby matching electrical output characteristics of the solar cell fabric unit and the friction nano generator and thus realizing simultaneous and integrated outputting. Therefore, a technical problem that the friction nano generator with the high output impedance is easy to be in a shot circuit state by the low-impedance solar cell can be solved. The provided integration solution has advantages of light weight, easy integration and prevention of manual adjustment all the time.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a connection method for simultaneously integrating and outputting electric energy between a solar cell fabric and a friction nanogenerator. Background technique [0002] With the vigorous development of smart wearable devices, people's demand for light and cheap portable, flexible and sustainable power sources has become increasingly prominent. People have always dreamed of realizing a power supply technology that can be woven into clothes, which can collect various environmental energies such as light, wind, and body movement, and convert them into electrical energy to drive portable electronic devices to work continuously. [0003] In recent years, a class of triboelectric nanogenerators (TENG) based on the combination of triboelectrification and electrostatic induction has been developed. This new generation technology can be used to convert mechanical energy into electrical...
