Solar cell module for sunlight room and preparation method thereof

Abstract

The invention discloses a solar cell module for a sunlight room and a preparation method thereof. The solar cell module for the sunlight room comprises a tempered glass layer, EVA film layers, a cell piece layer and a backboard; the EVA film layer is arranged at each of the upper and lower surfaces of the cell piece layer, the tempered glass layer adheres the upside of the cell piece, and the backboard adheres to the downside of the cell piece; a side frame is arranged at the periphery; the backboard comprises a PET layer at the middle, a fluorine-containing weather-resistant layer coats each of the upper and lower surfaces of the PET layer, the PET layer is 0.15 to 0.30 millimeters in thickness, the upper fluorine-containing weather-resistant layer is 0.008-0.014 millimeters in thickness, and the lower fluorine-containing weather-resistant layer is 0.015 to 0.025 millimeters in thickness; the side frame of each component is provided with a bump or a groove having sliding fit with the adjacent side frame, and the bump of the side frame is sleeved in the groove of the adjacent side frame in a sliding mode to realize component connection. The solar cell module for the sunlight room has advantages that the sunlight is soft, the indoor air flow and human settlement maintenance are facilitated, the sealing property is good, water leakage is avoided, and the conversion efficiency and light transmittance of the cell are high.

Description

technical field [0001] The invention relates to the technical field of solar cell components, in particular to a solar cell component for a sun room and a preparation method thereof. Background technique [0002] With the increasing scarcity of energy and the improvement of awareness of environmental protection and energy saving, the use of solar cells is getting more and more attention, and its utilization rate and penetration rate are also increasing, such as street lamps, power generation in factories, in addition, there are large shopping malls that are now popular Or the transparent roof used in the family is the sun room; the more mature solar cell modules used generally have a structure including cells, transparent glass placed on the upper and lower surfaces of the cells, and EVA film bonding between the cells and the transparent glass Together, and then framed as a whole to form a battery assembly. However, if this traditional solar cell module is directly applied ...

AI Technical Summary

Problems solved by technology

However, if this traditional solar cell module is directly applied to the sun room, photovoltaic roof, plastic greenhouse roof and other fields, the sunlight will be too dazzling, and the heat in the house will be high, which is not conducive to the indoor air circulation and the maintenance of the indoor living environment.

In addition, because the existing solar cell modules are directly used in the sun room, photovoltaic roof, plastic greenhouse roof and other fields, the modules are in rigid contact with each other, and their sealing performance is poor, and they are prone to water leakage. Low rate, low comprehensive utilization efficiency
