Description

一种太阳能电池用散热封装胶膜及其制备方法
技术领域
本发明涉及太阳能电池技术领域，具体涉及一种太阳能电池用散热封装胶膜及其制备方法。
背景技术
传统太阳能电池组件一般使用EVA(乙烯-醋酸乙烯共聚物)对电池片进行封装保护，并使用高耐候的氟膜材料作为背板，这两种高分子材料传热散热性能一般，导致组件在户外工作时产生的热量不能及时散发，聚集的热量极大降低了组件的电输出性能，由此产生的高温还会影响封装材料的稳定性，导致组件老化加速难以满足25年寿命。为此，一些传统组件厂商使用具有散热功能的金属散热背板来提高组件热量的传导和散热，使用多层散热封装材料和金属散热背板，组件结构复杂，叠层工艺繁琐，不适合组件的量产；也有公司将金属散热背板做了优化，在金属散热背板两侧分别作了绝缘粘接层和耐候层，但在使用过程中还是存在绝缘性隐患。
现有双玻组件替代传统组件，背板使用无机材料替代高分子材料有利于热量的传导和散热，但是封装材料仍是导热系数偏低的高分子材料，与无机材料界面存在较大热阻，很大程度上削弱了玻璃作为背板材料的散热功能。
发明内容
本发明所要解决的技术问题是：提供一种具有优异散热性能的太阳能电池用散热封装胶膜及其制备方法。
本发明解决其技术问题所采用的技术方案是：
一种太阳能电池用散热封装胶膜的制备方法，包括以下步骤：将胶膜基体、无机填料、交联剂、紫外吸收剂、光稳定剂混匀后采用双螺杆挤出机挤出造粒，然后将造好的粒用单螺杆挤出机挤出，挤出物经磨头挤出成型，即得；所述胶膜基体、无机填料、交联剂、紫外吸收剂、光稳定剂的质量比为800～1200:5～100:0.1～5:0.01～2:0.01～5；所述胶膜基体为电气绝缘树脂，所述无机填料为石墨烯、碳纳米管、碳纤维、氮化硼、二氧化钛、硫酸钡中的任意一种或几种。
所述电气绝缘树脂的体积电阻率大于1015Ω·cm，所述电气绝缘树脂的热熔融点为40～180℃。
所述电气绝缘树脂为聚烯烃、聚乙烯醇缩丁醛、离聚物、聚氨酯、有机硅树脂、环氧树脂中的任意一种或几种。
所述离聚物为Na离聚物、Zn离聚物、Mg离聚物中的任意一种。
优选的，所述聚烯烃为乙烯-辛烯共聚物、乙烯-丁烯共聚物中的任意一种。所述乙烯-辛烯共聚物、乙烯-丁烯共聚物，是饱和的脂肪链结构，且分子链中叔碳原子较少，具有良好的耐候性、耐紫外老化性能，优异的耐热、耐低温性能；另外，其与背板玻璃的粘结性较强，具有优良的界面粘合性能；以乙烯-辛烯共聚物或乙烯-丁烯共聚物为胶膜基体时，乙烯-辛烯共聚物或乙烯-丁烯共聚物具有更低的水蒸汽透过率，内聚力更大，更加适用于双玻组件，可使生产的双玻组件不需要封边，同时使用寿命更长。
上述采用双螺杆挤出机挤出造粒的温度为90～110℃。
所述无机填料的粒径为80～100nm。
优选的，所述无机填料为氮化硼、二氧化钛、硫酸钡中的任意一种或几种。
所述交联剂为过氧化二异丙苯或过氧化环己酮。
所述紫外吸收剂为本领域常用的紫外吸收剂，例如可以为紫外线吸收剂UV-531。
所述光稳定剂为本领域常用的光稳定剂，例如可以为光稳定剂770。
上述太阳能电池用散热封装胶膜的制备方法，还包括：将经磨头挤出成型后得到的胶膜采用预交联工艺处理使得胶膜表面的交联度达到10％以上。
所述预交联工艺为紫外光辐照固化或热固化。本发明的封装胶膜，采用预交联工艺进行预固化，减少胶的流动性，可以避免胶膜在层压过程中的翻胶现象，避免由于翻胶造成的遮挡电池片进而影响电池片工作效率的现象。
一种太阳能电池用散热封装胶膜，采用上述太阳能电池用散热封装胶膜的制备方法制得。
所述太阳能电池用散热封装胶膜的热传导率为0.43～0.73W/mk，反射率为76.3％～95.2％。
所述太阳能电池用散热封装胶膜用于电池片的非受光侧，即电池片与背板玻璃之间。
本发明的有益效果是：
本发明的太阳能电池用散热封装胶膜的制备方法，简单可行，采用电气绝缘树脂为胶膜基体，电气绝缘树脂具有较好的隔水性，水汽透过率低且体积电阻率大，能够保证电池组件在高温高湿环境下运行的安全性及长久的耐老化性，使得组件能够长久的使用；本发明采用的无机填料均为高导热系数无机填料，将高导热系数无机填料与本发明的胶膜基体掺杂制备封装胶膜，不仅能够提高热量的传导和散热，使太阳能电池组件输出功率有效能加，提高发电效益，还使得制备的胶膜具有高的反射率，增加了透过光的利用率，进一步增加太阳能电池组件的输出功率。
本发明的太阳能电池用散热封装胶膜，其热传导率为0.43～0.73W/mk，具有较好的散热性能，有效的降低组件的工作温度，从而避免太阳能电池组件在户外使用过程中产生的高温影响封装材料的稳定性，减缓组件老化，保证组件正常运行的25年使用寿命。
