Description

太阳复合膜电池
技术领域：
本发明是一种吸收太阳光中红外线、可见光、紫外线、X射线并将其转换成电能，为用电负载提供电力的一种新型太阳电池。
背景技术：
现有太阳电池，国内外基本上都是硅材料制成。硅材料只能吸收太阳光波长0.3-0.7μm的可见光；而波长大于可见光的红外线和小于可见光的、紫外线、X射线不能吸收，也不能转换成电力。使太阳电池功率低、造价高，使用价值大大降低。
发明专利《太阳电池》专利号ZL93102702.0，虽然能吸收太阳光的可见光和非可见光光产生电能，但是，制造工艺太复杂，实施困难，且电压也低，大批量生产、使用都有困难.
发明内容：
本发明的目的：就是提供一种不但能吸收太阳光的可见光和非可见光的红外线、紫外线、X射线发电，而且，工艺简单、制造容易，实施方便、电压高，易用于航天、航空、交通工具和建大规模电站的一种太阳电池-太阳复合膜电池。
本发明是这样实现的：
选择透光率97％以上，厚度0.9μm膨胀系数小、耐高温的聚脂膜作为衬底。
在衬底膜上，用铟(in)材料制作正电极并划线分成膜块。在正电极层上用锗(Ge)材料制作能吸收红外线的镀膜；在能吸收红外线膜层上，再用硅(Si)材料制作吸收可见光的膜层；吸收紫外线、X射线的膜层用铋(Bi)材料制作在吸收可见光膜层上；然后，用激光刻线机将红外线层、可见光层、紫外线、X射线层划线分成与正电极块相对应相距5mm的块，作为子电池。在子电池层上，再用银(Ag)做背电极层并用激光短波划线成与子电池相对应相隔8mm的块。此时，太阳复合膜电池制作完毕.
本发明的优点：与普通太阳电池比较有：转换效率高、重量轻、电压高、用途广，易作航天、航空、太阳轿车等发电装置。
附图说明：
图1、太阳复合膜电池外形示意图
图2、太阳复合膜电池侧面剖视示意图
具体实施方式：
参照图2，选择无色透光率97％，厚度0.9μm的聚脂薄膜1作衬底；在聚脂薄膜1上作正电极2.具体实施方法：在真空磁控镀膜机内，设置厚度0.9μm的聚脂薄膜1.在聚脂薄膜1上方固定用铟(in)材料制成的靶材.距离聚脂薄膜200mm，真空度100Pa，实施镀膜，膜层2膜厚60nm停止。用激光划线机，波长0.56μm，相隔15mm，在膜2上划线7
在薄膜2上，制膜层3，具体方法：用真空离子镀膜机，将锗(Ge)作靶材。将薄膜2置于工件架上，电压800V实施镀膜，膜厚80μm停止，膜层3制完。
用PE-CVD设备在膜层3上，制膜层4。具体方法：把膜层3平展于工件床上，将掺有5％乙硼烷(B2H6)硅烷(SiH4)，作为沉积材料，压强90Pa，流量60ml/min，实施镀膜，膜厚25(埃)停止，膜层4制完。
在膜层4上制作膜层5，用GD-VCD设备，将铋(Bi)为靶材，放在设备内材料架上，垂直对准工件，相距50mm，工作压强10-6Pa，电压600V(DC)，功率3KW，即可实施镀膜，膜厚260μm停止镀膜，膜层5制作完毕。
用激光刻线机，光束波长0.32μm与膜层2上划线7垂直相隔6mm划线8，子电池制作完毕.
在膜层5上，制作背电极6.具体方法：用真空蒸发镀膜设备，将银(Ag)丝，作为镀膜材料置于材料架上，工作压强10-3Pa实施镀膜，膜厚20nm停止.用激光刻线机，波长0.18μm与划线8垂直对应相隔5mm划线9，此时电池背电极制作完毕.至此，太阳复合膜电池制作完毕。
上述方案为最佳方案，如果膜层4用砷化镓作靶材，效果也较好，与上述方案相比，转换效率稍差。
