Abstract:
(EN) A glass powder used for fabricating a photovoltaic cell electrode, a paste composition comprising the same, a photovoltaic cell electrode, and a photovoltaic cell. The glass powder comprises sodium tellurite pentahydrate and lead tetraoxide. The glass powder comprises lead tetraoxide-sodium tellurite, having a high eutectic point, and being able to provide a certain space for controlling the reactivity of the glass powder and silicon nitride. The element Na in the composite compound Na2TeO3 may also form an Ag-Na ion complex, which may promote the liquid phase sintering of Ag particles during a sintering process. Therefore, the lead tetraoxide-sodium tellurite glass composition may provide a stable reactivity with silicon nitride such that a photovoltaic cell has excellent and stable contact resistance. A photovoltaic cell electrode prepared by applying the described paste composition, as well as a solder strip, have excellent adhesive strength and minimize series resistance (Rs), thus providing high conversion efficiency.
(FR) L'invention concerne une poudre de verre utilisée pour fabriquer une électrode de cellule photovoltaïque, une composition de pâte la comprenant, une électrode de cellule photovoltaïque et une cellule photovoltaïque. La poudre de verre comprend du tellurite de sodium pentahydraté et du tétraoxyde de plomb. La poudre de verre comprend du tétraoxyde de plomb-tellurite de sodium, présentant un point eutectique élevé et étant en mesure de fournir un certain espace pour réguler la réactivité de la poudre de verre et du nitrure de silicium. L'élément Na dans le composé composite Na2TeO3 peut également former un complexe d'ions Ag-Na, qui peut favoriser le frittage en phase liquide de particules d'Ag au cours d'un procédé de frittage. Par conséquent, la composition de verre de tétraoxyde de plomb-tellurite de sodium peut fournir une réactivité stable avec du nitrure de silicium de sorte qu'une cellule photovoltaïque présente une excellente résistance de contact, stable. Une électrode de cellule photovoltaïque préparée par application de la composition de pâte décrite, ainsi qu'une bande de soudure, présentent une excellente force adhésive et réduisent au minimum la résistance en série (Rs), ce qui permet d'obtenir une efficacité de conversion élevée.
(ZH) 一种用于制备太阳能电池电极的玻璃粉料、包括其的糊剂组合物、太阳能电池电极及太阳能电池。其中,该玻璃粉料包含五水合亚碲酸钠和四氧化三铅。玻璃粉料含有四氧化三铅-亚碲酸钠,具有较高的共晶点,可以为控制玻璃粉与氮化硅的反应性提供一定的空间。Na 2TeO 3中的复合化合物Na元素也可以形成Ag-Na离子络合物,在烧结过程中可以促进Ag颗粒的液相烧结。因此,四氧化三铅-亚碲酸钠玻璃组合物可以提供与氮化硅的稳定的反应性,并使太阳能电池具有优异且稳定的接触电阻。应用上述糊剂组合物制备的太阳能电池电极,和焊带有优异的粘合强度并且使串联电阻(Rs)最小化,从而提供高转换效率。
