A portable, self-cleaning and heat-dissipating photovoltaic tile with high power generation gain

Abstract

The invention discloses a portable self-cleaning heat-dissipating type high-power generation gain photovoltaic tile. The photovoltaic tile fixes the photovoltaic battery module in a tile frame, and the tile frame is in a wave shape. The traditional power generation unit is changed from plane design to wave arc shape, When there is a small amount of cleaning liquid, This structure gathers the liquid together, it has a good cleaning effect, In addition, on the one hand, the arc-shaped design is favorable for reflecting the light irradiated on the photovoltaic tile frame onto the photovoltaic cell and improving the light absorption amount of the cell; on the other hand, the arc-shaped design of the cell sheet can reduce the light reflection amount on the surface of the cell, thereby improvingthe light absorption efficiency of the photovoltaic cell module and further improving the power generation gain of the cell.

Description

【Technical field】 [0001] The invention belongs to the field of photovoltaics and building materials, and in particular relates to a portable, self-cleaning and heat-dissipating photovoltaic tile with high power generation gain. 【Background technique】 [0002] At present, the global photovoltaic industry is developing rapidly. Photovoltaic energy is considered to be the most important new energy in the 21st century because of its sufficient cleanliness, safety and relatively extensive resources. Among them, as an important aspect of photovoltaic applications, BIPV has broad market development prospects. Photovoltaic tiles have received more and more attention because they can be perfectly combined with buildings. Photovoltaic tile is a combination of photovoltaic power generation unit and traditional tile technology, which is a functional reform of traditional tiles. Not only has the functions of leak prevention and decoration, but also adds the function of green power gene...

AI Technical Summary

Problems solved by technology

However, there are generally three problems in current photovoltaic tile products, which limit the application of photovoltaic tiles

First, photovoltaic tiles usually use bulky ceramic materials as the tile frame. On the one hand, the weight of photovoltaic tiles is increased, which is not conducive to installation; Negatively affect the power generation performance of the battery

The second problem is that the photovoltaic cell components of the photovoltaic tile are usually a flat structure. Once this structure is installed on the roof, it will become difficult to clean the dust, which will seriously affect the power generation of the battery. New design schemes are adopted to improve the efficiency of photovoltaic tiles. The self-cleaning ability is particularly important

The third problem is that because the photovoltaic modules in the photovoltaic tiles are designed in a plane, this design absorbs less external scattered light, resulting in low power generation gain of the battery and low economic efficiency
