Abstract

The present invention relates to a solar lower heat generating antetype device and making method which can utilize the heat of the sun shine to generate in low temperature. At present the relative art which can convert the lower temperature of the solar energy to electricity has not been found. The insulating material base board of the present invention is provided with a P type lower flat electrode and a N type flat electrode; the P type Bi2Te3 thermoelectric material post and the N type Bi2Te3 thermoelectric material post are respectively connected on the P type lower plate electrode and the N type lower plate electrode; the upper plate electrode is positioned on the P type convert body and the N type convert body; and the vanadium titanium porcelain heat absorbing plate is arranged on the upper plate electrode. The present invention combines the heat absorbing material with the thermoelectric material; the present invention utilizes the Bi2Te3 thermoelectric material to convert the heat energy of the lower temperature heat to electricity; and the present invention realizes to generate electricity with the heat energy of the sunshine.

Description

technical field [0001] The invention relates to a solar low-temperature heat utilization power generation prototype device and a manufacturing method for low-temperature power generation by utilizing the thermal energy of sunlight. Background technique [0002] With the issue of energy shortage becoming the focus of great attention, people are turning their attention to the utilization of renewable solar energy. There are two ways to convert solar energy into electricity, namely thermoelectric conversion and photoelectric conversion. The utilization of solar energy mainly includes low-temperature thermal utilization and solar photovoltaic utilization. The cost of photovoltaic technology of solar energy is relatively high, and it is generally used in solar cells and the like. The low-temperature heat utilization of solar energy is mainly used for heating and supplying hot water, such as solar water heaters. The use of thermoelectric materials to generate electricity is ach...
