Embodiment 1

[0077] A 100 μm sheet of Halar (ethylene chlorotrifluoroethylene copolymer, ECTFE) from Solvay Solexis was placed on the glass surface. A 23 g / m 2 Glass fiber prepreg (Cycom® 759F 70% A1100 / 23gsm glass fiber). The glass transition temperature of the thermosetting polymer of the prepreg is >135°C. Another solar cell, SunPower A300 (crystalline silicon photovoltaic device), was placed with the light-sensitive side facing down. Then place another piece of 23g / m on top of it 2 glass fiber prepreg (Cycom® 759F 70% A1100 / 23gsm glass fiber).

[0078] After placing the release film, placing the pressure divider / vent valve and vacuum bag, applying a vacuum of 5 mbar, the laminate was degassed for 4 h. Subsequently, the temperature was raised to 100° C., and the laminate was cured for 4 hours. Subsequently, the laminate was allowed to cool to room temperature. The vacuum was released at room temperature to obtain a 14*14 cm solar cell laminate containing crystalline silicon ph...

Embodiment 2

[0081] A 100 μm sheet of Halar (ethylene chlorotrifluoroethylene copolymer, ECTFE) from Solvay Solexis was placed on the glass processing surface. Put a piece of 49g / m on top of the Halar tablet 2 Glass fiber prepreg (MTM59 / GF1200-50%RW). The glass transition temperature of the thermosetting polymer of the prepreg is >135°C. Another solar cell, SunPower A300 (crystalline silicon photovoltaic device), was placed with the light-sensitive side facing down. Place another piece of 49g / m on top of it 2 Glass fiber prepreg (MTM59 / GF1200-50%RW).

[0082] After the release film was placed, the pressure divider / vent valve and vacuum bag were placed, a vacuum of 5 mbar was applied and the laminate was degassed for 4 h. Subsequently, the temperature was raised to 100° C., and the laminate was cured for 4 hours. Subsequently, the laminate was allowed to cool to room temperature. The vacuum was released at room temperature to obtain a 14*14 cm solar cell laminate containing cr...

Embodiment 3

[0085] Place a release film on the glass processing surface. Place a piece of 49g / m on the release film 2 Glass fiber prepreg (MTM59 / GF1200-50%RW). The glass transition temperature of the thermosetting polymer of the prepreg is >135°C. Place the solar cell SunPower A300 (crystalline silicon photoelectric device) with its photosensitive side facing down. Place another piece of 49g / m on top of it 2 Glass fiber prepreg (MTM59 / GF1200-50%RW).

[0086] After placing the release film, place the pressure divider / vent valve and vacuum bag and apply a vacuum of 5 mbar. The laminate was degassed for 4 h. Subsequently, the temperature was raised to 100° C., and the laminate was cured for 4 hours. Subsequently, the laminate was allowed to cool to room temperature. The vacuum was released at room temperature to obtain a 14*14 cm solar cell laminate containing crystalline silicon photovoltaic devices with a size of 12*12 cm. The thickness of the laminates is between 200 and 4...

Description

technical field [0001] The present invention relates to a solar cell laminate comprising a crystalline silicon photovoltaic device. The invention also relates to a method for preparing the solar cell laminate comprising crystalline silicon photovoltaic devices, and the use of such a solar cell laminate. Background technique [0002] Crystalline silicon photovoltaic devices are known for their ability to efficiently convert solar energy into electricity. The crystalline silicon used in such devices is extremely fragile. Therefore, these devices are usually protected with a layer of fiberglass. In some applications, it is desirable to be able to obtain curved shapes of crystalline silicon devices. For most curved shape applications, thin-film solar cells are used. Since thin film solar cells are less efficient than crystalline silicon cells, in some applications it is desirable to use curved shapes of crystalline silicon. [0003] Various techniques are available to obt...
