Self-generating device and electric equipment

Abstract

The invention provides a self-power-generation device and electric equipment. The self-power-generation device comprises a photovoltaic power generation assembly and a thermoelectric power generation assembly which are arranged in parallel. The photovoltaic power generation assembly comprises a first power generation layer and a second power generation layer which are stacked, and the first power generation layer and the second power generation layer are different semiconductor layers in an N-type semiconductor layer and a P-type semiconductor layer; the thermoelectric power generation assembly comprises a third power generation layer and a fourth power generation layer, the third power generation layer is a hot end layer, and the fourth power generation layer is a cold end layer; the third power generation layer and at least part of the second power generation layer are reused. The fourth power generation layer is arranged on the side, away from the first power generation layer, of the second power generation layer. The heat of the photovoltaic power generation assembly in the power generation process can meet the heat requirement of the thermoelectric power generation assembly, so that the effects of common power generation and parallel output are achieved, and the power generation efficiency can be improved; and the thermoelectric power generation assembly can continuously generate power in a scene without a light source but with a heat source, so that the power generation efficiency of the self-power-generation device can be further improved.
