中文摘要: |
采用卷对卷工艺制备了叠层非晶硅/非晶硅锗(a- Si/a-SiGe)电池,采用激光刻划与丝网印刷实现集成串联, 形成柔性薄膜电池集成串联组件。研究了SiGe电池渐变带隙、柔性衬底nip倒结构激光刻 划、反向脉冲电治疗,并用以改善柔性薄膜电池集成内联组件性能。集成组件有5个子电池 内部串联而成,有效面积转换效率达5.424%(AM0,100.1cm2),开路电压达7.156V。 |
英文摘要: |
The key technologies of flexible monolithically series-integrated a -Si thin film modules on polymer substrate are studied and the modules are fabricated.Tandem a-Si/ a-SiGe solar cell can obtain higher convention efficiency and laser scribing is very important in monolithic module fabrication.The SiGe grading band gap,laser scribing of nip typed solar cell a nd electrical curing to remove shunts are discussed and used to improve monolithic module′s perform ance.On polyimide substrate,the back reflector Ag/ZnO is sputtered by roll-to-roll sp uttering machine,the n-i-p a-Si/a-SiGe is deposited by roll-to-roll plasma enhanced chemical va por deposition (PECVD) machine,and the ITO layer is sputtered by roll-to-roll sputtering machine with a mask.At last,monolithic series integr ation is obtained by laser scribing and screen printing.A monolithic module includes five cell strip es,and the best conversion efficiency is 5.424%(AM0,0.1cm2)with open volt age of 7.156V. |
