3的掺杂浓度以及磁控溅射制备工艺的不同,AZO层的透光率和电阻率也存在差异。目前的CIGS薄膜太阳能电池组件中,AZO层的厚度约为800nm~1200nm。
AZO层通常是利用真空磁控溅射镀膜设备进行制备,真空磁控溅射镀膜设备占地空间比较大,且设备价格较高,维护成本高。另一方面,受限于AZO层本身导电性和透光率的负相关关系,即AZO层的厚度越大,导电性越好,但同时透过率越低,导致目前工艺条件下,AZO层的厚度需要达到800nm~1200nm,才能兼顾较好的导电性和透过率。此外,AZO层的光电性质依赖于AZO层制备过程中的靶材的结构和组分,并且要求具有可靠、稳定的制备工艺,对制备工艺要求高,制备难度大。

图1是根据本公开的一个实施例的铜铟镓硒太阳能电池组件的结构示意图,如图1所示,铜铟镓硒太阳能电池组件包括:基板1,设置在基板1上的背电极2,设置在背电极2上的光吸收层3,设置在光吸收层3上的缓冲层4,设置在缓冲层4上的窗口层,设置在窗口层上的乙烯-醋酸乙烯共聚物(EVA)层7,和设置在EVA层7上的玻璃层8。
其中,窗口层包括i~ZnO薄膜即高阻层5和透明导电层6,透明导电层6包括设置在高阻层5上的石墨烯基复合薄膜。在本公开的一个实施例中,石墨烯基复合薄膜包括:石墨烯薄膜和设置在石墨烯薄膜上的纳米线。其中,石墨烯薄膜为单层或少层石墨烯薄膜,石墨烯薄膜的厚度为大于0且小于等于1nm。石墨烯基复合薄膜的透光率可高达94%,同时电阻率低于8Ω/sq,性能显著优于AZO薄膜性能,具有优良的透光性和低电阻率。
单层石墨烯(Graphene):指由一层以苯环结构(即六角形蜂巢结构)周期性紧密堆积的碳原子构成的一种二维碳材料,厚度一般为0.33nm。
少层石墨烯(Few~layer):指由3~10层以苯环结构(即六角形蜂巢结构)周期性紧密堆积的碳原子以不同堆垛方式(包括ABC堆垛,ABA堆垛等)堆垛构成的一种二维碳材料。
根据本公开的一个实施例,纳米线为网络结构的纳米线,其中,纳米线可以包括至少一种金属纳米线,也可以是至少一种非金属纳米线,如碳纳米管等。

进一步的,AZO层9设置在高阻层上,纳米线网格结构设置在接近高阻层5的一面,或者,纳米线网格结构设置在远离高阻层5的一面,对此本公开不做具体限定。
与设置于接近高阻层的一面相比,纳米线设置于在远离高阻层的一面时,在利用热压印方法转移到EVA薄膜的过程中,减少了高温对金属纳米线的损伤,同时也降低了工艺难度。
图3是根据本公开的一个实施例的铜铟镓硒太阳能电池组件的制作方法的流程框图。如图3所示,将石墨烯基复合薄膜作为铜铟镓硒太阳能电池组件的前电极的具体实施过程如下:
S110,制备背电极2:将钼沉积到基板上以形成钼层薄膜。
在一实施例中,可以利用真空磁控溅射方法将钼沉积到基板1上以形成钼层薄膜。其中,钼层膜膜作为电池芯片的背电极。钼层薄膜厚度为300nm~500nm。其中,基板1可以为玻璃基板,如清洁的钢化玻璃。
S120,制备光吸收层3:在钼层薄膜表面沉积铜、铟、镓、硒以形成铜铟镓硒薄膜。
在一实施例中,可利用共蒸发沉积方法或者磁控溅射硒化方法,在钼层薄膜表面沉积铜、铟、镓、硒以形成铜铟镓硒薄膜。其中,铜铟镓硒薄膜作为光吸收层3,且铜铟镓硒薄膜的薄膜厚度为2μm~3μm。
S130,制备缓冲层4:在铜铟镓硒薄膜表面沉积硫化镉以形成硫化镉薄膜。
在一实施例中,可利用化学水浴沉积方法在铜铟镓硒薄膜表面沉积硫化镉以形成30nm~80nm厚的硫化镉(CdS)薄膜。其中,硫化镉薄膜作为缓冲层4。
S140,制备窗口层。
在一实施例中,制备窗口层包括:
S141,在硫化镉薄膜表面沉积本征氧化锌(i~ZnO),以形成本征氧化锌薄膜。
在一实施例中,可利用真空磁控溅射方法,在硫化镉薄膜表面沉积本征氧化锌以形成厚度为50nm~100nm的本征氧化锌薄膜,即高阻层5。
可选的,在一实施例中,制备窗口层还包括:
S142,在本征氧化锌薄膜表面沉积氧化锌铝(AZO)以形成AZO薄膜。
在一实施例中,可利用真空磁控溅射方法,在本征氧化锌薄膜表面沉积氧化锌铝以形成AZO薄膜。其中,AZO薄膜的厚度为大于0且小于等于400nm。
S150,将石墨烯基复合薄膜转移到EVA层7的表面。
在一实施例中,可采用热压印转移的方法将石墨烯基复合薄膜转移到EVA层7的表面。
S160,利用带有石墨烯复合薄膜的EVA层封装所述钼层镀膜、铜铟镓硒薄膜、硫化镉薄膜和本征氧化锌薄膜。
在上述步骤之后,完成后续封装过程即可得到铜铟镓硒薄膜太阳能电池组件,如图1和图2所示。
在步骤S150中,如果要把石墨烯复合薄膜转移到本征氧化锌薄膜上,目前比较成熟的转移工艺是溶液辅助转移方法,但本征氧化锌与溶液接触很容易引起其物理化学性质变化,因此采用热压印转移的方法将石墨烯基复合薄膜转移到EVA层表面,再用EVA层进行封装,以实现将石墨烯基复合薄膜设置到本征氧化锌薄膜上,而不会引起本征氧化锌的物理化学性质的变化。
进一步的,石墨烯复合薄膜的厚度不到1nm,非常薄,如果直接覆盖到本征氧化锌薄膜上,很容易造成石墨烯基复合薄膜破裂、折叠等,用热压印转移的方法将石墨烯基复合薄膜转移到EVA层表面,可以解决这个问题。
图4是根据本公开的一个实施例的铜铟镓硒太阳能电池组件的制作方法的流程框图。图4所示的铜铟镓硒太阳能电池组件的制作方法与图3所示的铜铟镓硒太阳能电池组件的制作方法相似,两者之间的不同之处在于:图4所示的铜铟镓硒太阳能电池组件的制作方法,在步骤S150之前,还包括:S143,制作石墨烯基复合薄膜:在石墨烯薄膜上制备一层金属纳米线网络结构,以形成石墨烯基复合薄膜。在一实施例中,可利用喷涂或旋涂的方法在石墨烯 薄膜上制备一层金属纳米线网络结构,以形成石墨烯基复合薄膜。其中,纳米线直径≤100nm,石墨烯基复合薄膜的厚度≤200nm。其中,石墨烯薄膜可以为石墨烯薄膜单层或少层石墨烯薄膜,通常是生长在铜箔表面,厚度≤1nm。
在本公开实施例中,所述石墨烯基复合薄膜的厚度≤200nm,比起相关技术中的AZO薄膜约为800nm~1200nm的厚度,厚度明显变薄,并且使用喷涂或旋涂的方法制作石墨烯基复合薄膜,降低了工艺难度,同时石墨烯基复合薄膜的透光率可高达94%,同时电阻率低于8Ω/sq,具有优良的透光率和低电阻率,性能显著优于AZO薄膜。
根据本公开的另一个实施例,铜铟镓硒太阳能电池组件的制作方法,包括以下步骤S201至S207。
S201,制备背电极:将钼沉积到基板上以形成钼层薄膜。
在一实施例中,可以利用磁控溅射技术对清洗后的玻璃基板进行钼层镀膜以形成钼层薄膜。其中,该钼层薄膜的厚度为200nm~500nm,薄膜方块电阻为500mΩ~1000mΩ。
S202,制备光吸收层:在钼层薄膜表面沉积铜、铟、镓、硒以形成铜铟镓硒薄膜。

2薄膜。铜铟镓硒薄膜作为光吸收层,光吸收层的厚度为1.8μm~2.5μm。在一实施例中,铜与第三族元素的原子比例在0.75~1之间。镓与第三族元素的原子比例在0.2~0.5之间。
S203,制备缓冲层:在铜铟镓硒薄膜表面沉积硫化镉以形成硫化镉薄膜。
在一实施例中,可利用化学水浴法在铜铟镓硒薄膜表面沉积硫化镉以形成20nm~80nm厚的硫化镉薄膜。其中,硫化镉薄膜作为缓冲层。
S204,制备窗口层。
在一实施例中,可利用磁控溅射方法在硫化镉薄膜表面沉积本征氧化锌以形成本征氧化锌薄膜,即本征氧化锌高阻层;并石墨烯基复合薄膜转移到本征氧化锌薄膜上,形成窗口层。
在本公开的其它实施例中,在将石墨烯基复合薄膜转移到本征氧化锌薄膜上之前,S204还包括:在本征氧化锌薄膜表面沉积氧化锌铝(AZO)以形 成AZO薄膜。
在一实施例中,可利用磁控溅射方法在本征氧化锌薄膜表面沉积铝掺杂氧化锌以形成铝掺杂氧化锌(AZO)层。此时,本征氧化锌薄膜即高阻层、石墨烯基复合薄膜和AZO层共同作为窗口层。其中,AZO层的厚度为50nm~400nm。
S206,利用EVA薄膜封装所述钼层镀膜、铜铟镓硒薄膜、硫化镉薄膜、本征氧化锌薄膜和石墨烯基复合薄膜。

S207,通过EVA薄膜敷设、层压等工艺,完成对太阳能电池组件的制备。
本公开实施例所涉及的铜铟镓硒太阳能电池组件的制作方法,通过在铜铟镓硒太阳能电池组件制备过程中引入石墨烯基复合薄膜充当透明导电层,有效的提高铜铟镓硒薄膜太阳能电池组件透明导电层的透光性和导电性,提高了铜铟镓硒太阳能电池组件的转换效率,并且降低了透明导电层的制备难度,同时也降低了铜铟镓硒太阳能电池组件的制备难度。
上述实施例仅供说明本公开之用,而并非是对本公开的限制,有关技术领域的普通技术人员,在不脱离本公开范围的情况下,还可以做出各种变化和变型,因此,所有等同的技术方案也应属于本公开公开的范畴。
