Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] Such as figure 1 As shown, a radiation cooling solar cell assembly includes a solar cell 1, the bottom layer of the solar cell is a metal reflective layer 4, and the other side of the solar cell is provided with a visible-near-infrared high-transmittance / mid-infrared absorbing film layer 2. The upper part of the visible-near-infrared high-transmittance / mid-infrared absorption film layer is provided with a visible-near-infrared high-transmission / mid-infrared anti-reflection film layer 3, and light is incident from the side of the visible-near-infrared high-transmission / mid-infrared anti-reflection film layer. Here the solar cells are polycrystalline silicon solar cells. The metal reflective layer 4 is located under the polysilicon solar cell to reflect unused solar energy and near-infrared energy. The metal reflective material can be selected from silver, alu...

Abstract

The invention discloses a radiation cooling solar cell module, which comprises a solar cell, the bottom surface of the solar cell is provided with a metal reflective layer; ‑Near-infrared high-transmission / mid-infrared anti-reflection film layer, the visible-near-infrared high-transmission / mid-infrared absorption film layer is located between the top surface of the solar cell and the visible-near-infrared high-transmission / mid-infrared anti-reflection film layer. Incident from the visible-near-infrared high-transmittance / mid-infrared anti-reflection coating. Therefore, the radiation cooling solar cell of the invention is expected to be widely used in photovoltaic power generation, electromagnetic detection, energy utilization, refrigeration, etc., and contribute to the fields of national economy, social development, science and technology, and national defense construction in our country.

Description

technical field [0001] The invention belongs to the fields of photovoltaic power generation, electromagnetic detection, energy utilization, refrigeration and the like, and in particular relates to a radiation cooling solar cell assembly. Background technique [0002] Solar cells, as the key unit of solar energy, the largest clean energy on earth, have attracted continuous attention from the scientific and industrial circles in recent decades. Currently, there are two types of solar cell units widely used in the market: crystalline silicon solar cells and inorganic thin-film solar cells. In the third upsurge of solar energy innovation, organic solar cells have achieved rapid development, and the cells have entered the market stage in a small range at present. Whether these solar cells are crystalline silicon, inorganic thin films, or organic, their efficiency, lifespan, and manufacturing methods have been the focus of scientific and industrial research in recent years. In a...
