Description
技术领域technical field
本发明涉及太阳能光伏光热技术领域，特别是涉及一种光伏光热一体化装置。The invention relates to the field of solar photovoltaic photothermal technology, in particular to a photovoltaic photothermal integrated device.
背景技术Background technique
太阳能是一种清洁、经济、稳定的能源。我国的太阳能资源相对丰富，光伏发电和太阳能热水器产业经过几年的快速发展已经形成了产业化生产，技术不断创新，产品性能得到不断的改进优化，目前正在被广泛的应用。在光伏发电过程中，太阳能利用效率只有百分之十几，大量能量被电池吸收转换为热能，若对这些能量进行回收，可大大提高太阳能的利用率。Solar energy is a clean, economical and stable energy source. Our country is relatively rich in solar energy resources. After several years of rapid development, the photovoltaic power generation and solar water heater industries have formed industrialized production, with continuous technological innovation and continuous improvement and optimization of product performance. They are currently being widely used. In the process of photovoltaic power generation, the utilization efficiency of solar energy is only more than ten percent, and a large amount of energy is absorbed by the battery and converted into heat energy. If the energy is recovered, the utilization rate of solar energy can be greatly improved.
对于平板晶硅太阳能电池，工作电压(Vmp)的温度系数约为-0.0045/℃；开路电压(Voc)的温度系数约为-0.0034/℃。对于薄膜太阳能电池，工作电压(Vmp)的温度系数约为-0.0028/℃(折合70℃的系数为0.874)；开路电压Voc的温度系数约为-0.0028/℃(折合-10℃时的系数为1.1)。 在光伏发电过程中，随着太阳能电池结温，温度上升使太阳能电池开路电压Voc下降，短路电流Isc则轻微增大，总体会造成太阳能电池的输出功率下降。For flat crystalline silicon solar cells, the temperature coefficient of the operating voltage (Vmp) is about -0.0045/°C; the temperature coefficient of the open circuit voltage (Voc) is about -0.0034/°C. For thin-film solar cells, the temperature coefficient of the working voltage (Vmp) is about -0.0028/°C (the coefficient at 70°C is 0.874); the temperature coefficient of the open circuit voltage Voc is about -0.0028/°C (the coefficient at -10°C is 1.1). In the process of photovoltaic power generation, as the solar cell junction temperature rises, the open-circuit voltage Voc of the solar cell decreases, and the short-circuit current Isc increases slightly, which generally causes the output power of the solar cell to decrease.
针对太阳能电池温度升高会造成太阳能电池的输出功率下降的问题，对光电产业是一个重要的课题。Aiming at the problem that the output power of the solar cell will decrease due to the temperature rise of the solar cell, it is an important subject for the photovoltaic industry.

图1示出了本发明提供的光伏光热一体化装置的结构示意图，为了便于说明，本图仅提供与本发明有关的结构部分。Fig. 1 shows a schematic structural diagram of a photovoltaic photothermal integrated device provided by the present invention. For convenience of description, this figure only provides structural parts related to the present invention.
光伏光热一体化装置包括太阳能电池片阵列，太阳能电池片阵列的一侧设有钢化玻璃板1，另一侧设有背板，太阳能电池片阵列与钢化玻璃板1之间以及背板之间均粘结有EVA垫层2，太阳能电池片阵列包括多个依次通过焊带3相连呈阵列布置的太阳能电池片4，每相邻的两个太阳能电池片4之间均设有间隙；背板为透明背板5；透明背板5的下面粘结有蓝膜集热板，蓝膜集热板包括集热板芯8和镀设于集热板芯上表面的蓝膜镀层7。在该实施例中，采用铝合金材质的集热板芯则可提高其导热性能，提高导热效率。由于在相邻的两个太阳能电池片4之间均设置了间隙，提升了太阳能电池片4的散热能力，并且使用透明背板5，不仅能提高太阳光的光透率，还可高效地传递太阳能电池片4进行光电转换过程中产生的热量；而透明背板下面粘结的蓝膜集热板，则能够快速且高效地吸收透明背板传递的太阳能电池片4在光电转换过程中所产生的热量及透过太阳能电池片4之间的间隙的太阳光直射光热，并迅速进行光热转换，而后通 过集热板芯8将其吸收和转换的热量传递出去，并被人们回收利用。The photovoltaic photothermal integrated device includes a solar cell array, one side of the solar cell array is provided with a tempered glass plate 1, and the other side is provided with a back plate, and the space between the solar cell array and the tempered glass plate 1 and between the back plate Both are bonded with an EVA cushion layer 2, and the solar cell array includes a plurality of solar cell sheets 4 that are connected in an array through welding ribbons 3 in sequence, and gaps are provided between every two adjacent solar cell sheets 4; It is a transparent backboard 5; a blue film heat collecting plate is bonded to the bottom of the transparent back plate 5, and the blue film heat collecting plate includes a heat collecting plate core 8 and a blue film coating 7 plated on the upper surface of the heat collecting plate core. In this embodiment, the heat-collecting plate core made of aluminum alloy can improve its heat conduction performance and heat conduction efficiency. Since gaps are provided between two adjacent solar cells 4, the heat dissipation capacity of the solar cells 4 is improved, and the use of a transparent back plate 5 not only improves the light transmittance of sunlight, but also efficiently transmits The heat generated during the photoelectric conversion process of the solar cells 4; and the blue film heat collector plate bonded under the transparent back plate can quickly and efficiently absorb the heat generated by the solar cells 4 transmitted by the transparent back plate during the photoelectric conversion process. The heat from the solar cells 4 and the sunlight passing through the gaps between the solar cells 4 are directly irradiated with light and heat, and the light and heat are quickly converted, and then the heat absorbed and converted is transferred out through the heat collector plate core 8, and is recycled by people.
以太阳能电池板阵列整体的长度方向为横向，宽度方向为纵向，将太阳能电池片4与该间隙之间的分布比例设置为横向1:3～1:5，纵向1:2～1:3，则可使太阳能的总体利用率达到较佳状态，其中将该分布比例设置为横向1:4和纵向1:2.5，则可使太阳能的总体利用率达到最高。当然，将该分部比例设置为横向1:3或1:5，纵向1：2或1:3也能取得相近或相似的技术效果。Taking the overall length direction of the solar cell panel array as the horizontal direction and the width direction as the vertical direction, the distribution ratio between the solar cells 4 and the gap is set to be 1:3 to 1:5 in the horizontal direction and 1:2 to 1:3 in the vertical direction, Then the overall utilization rate of solar energy can reach a better state, where the distribution ratio is set to 1:4 in the horizontal direction and 1:2.5 in the vertical direction, then the overall utilization rate of the solar energy can be maximized. Of course, setting the division ratio to 1:3 or 1:5 in the horizontal direction and 1:2 or 1:3 in the vertical direction can also achieve similar or similar technical effects.
使用导热胶6将用透明背板5与蓝膜集热板粘结在一起，则有利于透明背板5与蓝膜集热板之间的光热传递，提高光能利用率。Using the heat-conducting adhesive 6 to bond the transparent back plate 5 and the blue film heat collecting plate together is beneficial to the light and heat transfer between the transparent back plate 5 and the blue film heat collecting plate, and improves the utilization rate of light energy.

The heat pipe 81 is fixedly connected with an upper cover plate 84 near the blue film heat collecting plate, and the heat pipe 81 is fixedly connected with a lower cover plate 85 at a side away from the blue film heat collecting plate. Using the heat collector plate core 8 with multiple heat pipes 81, the heat absorbed and converted by the blue mold coating 7 is transferred to the heat-conducting working medium, and then exported through the heat-conducting working medium, which can not only effectively reduce the working temperature of the solar cell 4, Improving the conversion efficiency of broadcasting and television is also conducive to the full utilization of solar energy and improving the conversion efficiency of light and heat. Moreover, the hot water is delivered to the water heater tank through the water outlet pipe 83 to provide domestic water, thereby achieving full utilization of solar energy and reducing energy consumption.
