Multiband hybrid light energy acquisition system, acquisition method and storage medium

Abstract

The invention relates to a multiband hybrid light energy acquisition system, an acquisition method and a storage medium. The acquisition system comprises a photoelectric conversion unit; an energy storage unit, connected with the photoelectric conversion unit; a voltage control unit, connected with the photoelectric conversion unit and the energy storage unit and used for adjusting the output voltage; a first photovoltaic cell, connected with the photoelectric conversion unit and suitable for collecting natural light, and the optical band gap of the first photovoltaic cell being within a firstpreset range; a second photovoltaic cell, connected with the photoelectric conversion unit and suitable for collecting artificial light, and the optical band gap of the second photovoltaic cell beingwithin a second preset range. The second photovoltaic cell is located above the first photovoltaic cell and is transparent, the maximum value of the second preset range is larger than the maximum value of the first preset range, and the minimum value of the second preset range is larger than the minimum value of the first preset range. According to the invention, the first photovoltaic cell and the second photovoltaic cell can be selectively assembled so as to improve the light energy utilization rate under complex illumination conditions.

Description

technical field [0001] This application relates to the field of new energy collection, in particular to a multi-band hybrid light energy collection system, collection method and storage medium. Background technique [0002] Photoelectric conversion is the process of directly converting solar radiation energy into electrical energy through the photovoltaic effect. The principle is that photons transfer energy to electrons to make them move and form current. [0003] With the development of electronic technology and manufacturing industry, the types of low-power products are gradually enriched, especially the arrival of the 5G era will greatly promote the development of the Internet of Things, when low-power wireless sensors will be all around us. Compared with electronic products that are constantly updated and iterated, the progress in power supply technology is much smaller, and the energy storage density of batteries has not improved much. Ambient energy harvesting system...
