Embodiment Construction

[0045] Existing solar cells can effectively collect sunlight energy for photovoltaic power generation in sunny days, but in rainy days or nights, the power generation efficiency of solar cells drops sharply or even disappears, and cannot work normally to provide electric energy.

[0046] The friction generator is a new type of technology invented in the past two years to convert mechanical energy into electrical energy. It uses the friction between two materials with different electronic capabilities to generate surface charge transfer, and can convert widely existing mechanical energy, such as wind energy. , the kinetic energy of various moving objects, and the energy in the form of human activities such as walking, running, beating, etc. are converted into electrical energy to provide power for small electronic devices such as portable devices. In particular, it has recently been discovered that water and some materials can also be triboelectrically charged, so that triboelec...

Abstract

The invention relates to a novel composite energy apparatus and a power generating method. The composite energy apparatus comprises a solar cell and a transparent friction generator covering on the surface of the solar cell. The transparent friction generator is used to replace a commercial proactive panel on the uppermost layer of the solar cell in rainy seasons or at night to form the novel composite energy apparatus; in sunny days, sunshine penetrates through the transparent friction generator, the solar cell can collect solar energy for realizing photovoltaic generation as usual; in rainy days when the photovoltaic generation efficiency is greatly reduced, the friction generator can collect rainwater energy for realizing friction power generation in an auxiliary manner; the transparent friction generator is used as the solar cell protective plate without influencing the photoelectric conversion efficiency on one hand, and on the other hand, the transparent friction generator can collect rainwater energy from the nature. According to the novel composite energy apparatus, the single photovoltaic generation solar cell panel is expanded into the composite energy cell system, and the brand new composite type green energy apparatus is realized, so that the composite energy apparatus is high in actual application value.

Description

technical field [0001] The invention relates to a novel composite energy device, in particular to a composite green energy system and power generation method capable of collecting solar energy and rainwater energy simultaneously or separately. Background technique [0002] In the current society, the lack of traditional energy and the pollution it brings have aroused people's attention. As an inexhaustible and environmentally friendly energy source, solar energy is one of the most promising new energy sources. Solar cells use the photoelectric effect or photochemical effect to directly convert solar energy into electrical energy, which is the most effective form of solar energy utilization. At present, solar cells have been maturely commercialized and widely used in roofs, roads and open and sunny places for photovoltaic power generation, which has become an indispensable way of power generation in our daily life. [0003] In actual production, in order to avoid environmen...
