Description
技术领域
本发明提供一种双面网状太阳能电池板,涉及太阳能发电领域。
背景技术
随着全球能源危机的不断加深,石油资源的日趋枯竭以及大气污染、全球气温上升的危害加剧,世纪能源危机、全球电力紧张、有很多地区备受停电困扰、给我们的生活带来很多不便。石油、煤炭等传统石化能源价格的不断高涨以及他们在燃烧过程中对全球气候和环境所产生的影响日益为人们所关注,已迫使全世界将目光聚集在新能源的开发。从资源、环境、社会发展的需求看,开发和利用新能源和可再生能源是必然的趋势。在新能源和可再生能源家族中,太阳能是取之不尽、用之不竭的清洁能源,太阳能电池是一种大有前途的新型电源,具有永久性、清洁性和灵活性的优点。太阳电池是一种对光有响应并能将光能转换成电力的器件。能产生光伏效应的材料有许多种,大部分太阳能电池板的主要材料为“硅”,如:单晶硅,多晶硅,非晶硅,砷化镓,硒铟铜等。它们的发电原理基本相同,现以晶体硅为例描述光发电过程。 P型晶体硅经过掺杂磷可得N型硅,形成P-N结。当光线照射太阳电池表面时,一部分光子被硅材料吸收;光子的能量传递给了硅原子,使电子发生了越迁,成为自由电子在P-N结两侧集聚形成了电位差,当外部接通电路时,在该电压的作用下,将会有电流流过外部电路产生一定的输出功率。太阳能电池板是通过吸收太阳光,将太阳辐射能通过光电效应或者光化学效应直接或间接转换成电能的装置,当许多个电池串联或并联起来就可以成为有比较大的输出功率的太阳能电池方阵。传统的太阳能电池板为单面设计,只能一个面受到太阳光照射,阳光照射面积小,发电效率较低,使光电转换效率不高。如何提高太阳能电池的发电量,是值得研究和探索的问题。
发明内容
本发明提供一种双面网状太阳能电池板,采用双面设计,使太阳能电池板两面受阳光照射,使太阳能电池板的阳光吸收率得到较大的提高,同时采用圆形网状结构,在单位面积内增大了阳光的照射面积,从而提高了太阳能电池板吸收太阳光的效率,达到发电效率最大化。
本发明解决其技术问题所采用的技术方案是:双面网状太阳能电池板由A钢化玻璃、网状太阳能电池组、圆形网孔、太阳能电池、B钢化玻璃、太阳能电池电源输出线、蓄电池、逆变器、蓄电池和逆变器电源连接线、交流电输出线等设备组成。
双面网状太阳能电池板,采用双面设计,使太阳能电池板两面受到阳光的照射。每块太阳能电池板由多组太阳能电池组成,每块太阳能电池板的规格可根据需求进行设定;每组太阳能电池可根据不同需求设计正方形或长方形,正方形或长方形内设有多个圆形网孔,圆形网孔的个数和孔径以及各孔间隙可根据需求进行确定,正方形或长方形的厚度,根据阳光照射条件和发电需进行确定。每组太阳能电池圆形网孔之间设有微孔,相互之间与大气相通,避免热胀冷缩引起的爆裂。每组太阳能电池圆形网孔的前后面设有钢化玻璃,保护太阳能电池不受尘土的污染,延长太阳能电池的寿命。每组太阳能电池通过电源连接线进行连接,使太阳能电池所发的电经电源连接线输送给蓄电池储存,再通过逆变器将直流电源转化为220V交流电供用户使用。
双面网状太阳能电池板安装在室外,安装方式为圆形网孔朝东西方向,有利于阳光的照射。当太阳从东方升起时,太阳光照射A钢化玻璃面的太阳能电池,同时太阳光通过圆形网孔照射到各组太阳能电池的内壁,B钢化玻璃面的太阳能电池虽然没受到阳光的直接照射,但日光仍然对B钢化玻璃面的太阳能电池起到一定补偿的作用,太阳能电池受到各方位太阳光作用,一部分光子被太阳能电池硅材料吸收;光子的能量传递给了硅原子,使电子发生了越迁,成为自由电子在P-N结两侧集聚形成了电位差,每组太阳能电池所产生的电流通过电源连接线输送给蓄电池储存,再通过逆变器将直流电源转化为220V交流电供用户使用。当太阳升到顶部时,太阳光照射A钢化玻璃面和B钢化玻璃面的太阳能电池,同时太阳光通过圆形网孔照射到各组太阳能电池的内壁,同样太阳能电池产生电流。当太阳光从西方下落时,太阳光照射B钢化玻璃面的太阳能电池,同时太阳光通过圆形网孔照射到各组太阳能电池的内壁,A钢化玻璃面的太阳能电池虽然没受到阳光的直接照射,但日光仍然对B钢化玻璃面的太阳能电池起到一定补偿的作用,太阳能电池受到各方位太阳光作用,同样每组太阳能电池所产生的电流通过电源连接线输送给蓄电池储存,再通过逆变器将直流电源转化为220V交流电供用户使用。
本发明的有益效果是:双面网状太阳能电池板,采用双面设计,使太阳能电池板两面受阳光照射,使太阳能电池板的阳光吸收率得到较大的提高,同时采用圆形网状结构,在单位面积内增大了阳光的照射面积,从而提高了太阳能电池板吸收太阳光的效率,达到发电效率最大化,优点在于降低发电成本、增大太阳能电池阳光照射面和发电量,适用于各类太阳能电池发电。
