光电幕墙的产生是在二十世纪初期,由于世界经济的发展,在一些国家出现能源危机,因此光电幕墙开始研发。那么什么是光电幕墙呢?它是一种集发电、隔音、隔热、安全、装饰功能于一体的新型建筑幕墙,它是用光电池、光电板技术,把太阳光转化为电能,它关键的技术是太阳能光电池技术。太阳能光电池是利用太阳光的光子能量,使得被照射的电解液或者半导体材料的电子移动,从而产生电压,这称为光电效应。多个太阳能光电池经加固处理,镶嵌在特殊的透明度极高的低铁玻璃中,彼此之间经过其背面的导线相连,从而构成了一个整体的光电板。

The emergence of photoelectric curtain wall was in the early twentieth Century. Due to the development of the world economy and the energy crisis in some countries, the photoelectric curtain wall began to research and develop. So what is the photoelectric curtain wall? It is a new type of building curtain wall, which integrates power generation, sound insulation, heat insulation, safety and decoration. It uses photovoltaic cells and photoelectric plate technology to convert sunlight into electric energy. The key technology is solar photovoltaic technology. Solar photovoltaic cells use the photon energy of the solar light to make the electrons of the irradiated electrolyte or semiconductor material move, thus generating the voltage, which is called the photoelectric effect. A number of solar photovoltaic cells are reinforced and embedded in a special transparent glass of low iron, which is connected to the traverse of the back of each other, thus forming a whole photoelectric plate.

光电板的尺寸规格可以根据实际工程的幕墙分格方案进行量体定型制作,在阳光照射下产生直流电,所有光电极产生的电能,通过多极集成电路整流,变压等过程,转化成供使用的交流电,送入用户电网。此幕墙体现了智能化特点,把太阳能光电技术集成到幕墙中不占有建筑面积,且太阳能光电板优美的外观,具有特殊的装饰效果,更赋予建筑物鲜明的现代科技色彩。

The size specification of the photoelectric plate can be made in volume according to the actual project's curtain wall partition scheme, producing DC under the sunlight, the electric energy produced by all optoelectronic poles, through the multipole integrated circuit rectifying, voltage variable and so on, converted into the alternating current for use, and sent to the user power grid. The curtain wall embodies the characteristics of intelligence, integrating solar optoelectronic technology into the curtain wall without building area, and the beautiful appearance of solar optoelectronic board, with special decorative effect, and more vivid modern scientific and technological color of the building.

设计时除考虑光电池组、光电板、导线、集成电路、整流器等各因素外,还需考虑幕墙传统的安全、防护、密封、装饰等功能,各项指标必须满足国家标准规定,使其达到比较佳使用效果。还要考虑安装方向,安装阳光照射时间长的部位,如墙楣部分或屋顶等应面南或东南、西南方向。还有双层玻璃幕墙,它是由双层结构组合而成的幕墙,内层一般都有能够开启的门窗,在外层幕墙的遮挡下,室外环境再恶劣也能保证内层门窗的正常开启,外层幕墙的进出风口和内层门窗的开启均能控制,内外层之间的热通道,可利用太阳能产生烟囱效应或温室效应,从而做到既保证必要的通风、换气,又能够节约能源。

In addition to the design of light battery, photoelectric board, wire, integrated circuit, rectifier and other factors, the traditional safety, protection, seal, decoration and other functions of the curtain wall must be considered. All the indexes must meet the national standard, so that it can achieve the best use effect. We should also consider installation direction and install long exposure parts, such as lintel or roof, facing south or southeast and southwest. There is a double glazing curtain wall, which is a curtain wall composed of double layer structure. The inner layer usually has the doors and windows that can be opened. Under the occlusion of the outer curtain wall, the outdoor environment can also ensure the normal opening of the inner and window doors and windows. The opening of the outlet of the outer curtain wall and the opening and opening of the inner and outer doors and windows can be controlled and the heat pass between the inner and outer layers. We can use solar energy to produce chimney effect or greenhouse effect, so as to ensure necessary ventilation, ventilation and energy saving.

它的原理,早在二十世纪三十年代就有人提出并进行实践,如当时法国建筑师皮埃尔卡洛设计的玻璃住宅就利用了这个原理,到二十世纪80年代首先在德国得到较为广泛的应用。如德国杜伊斯堡的商业促进中心幕墙工程、波恩邮政总局大楼幕墙工程、法国巴黎大学研究所幕墙工程、美国纽约的西方化学中心幕墙工程,被誉为典型的高层建筑的双层玻璃幕墙,这一高新技术产品的幕墙,在提高幕墙的隔热性能、生态环保功能和节省能源消耗等方面都有很大的突破。

Its principle, as early as in 1930s, was put forward and practiced. For example, the glass house, designed by the French architect Pierre Carlo, took advantage of this principle and was first used in Germany in 80s twentieth Century. For example, the curtain wall project of the commercial promotion center in Duisburg, the curtain wall project of the post office of Bonn post office, the curtain wall project of the Paris University Research Institute in France, the curtain wall project of the western chemical center in New York, USA, is known as the double glazing curtain wall of the typical high-rise building. The curtain wall of this high technology product is to improve the curtain wall. Great breakthrough has been made in thermal performance, eco environmental protection and energy saving.
