Abstract

La presente solicitud se aplica al campo técnico de las células solares y proporciona una tira de soldadura de forma especial para conexión de células de contacto posterior. La tira de soldadura de forma especial para conexión de células de contacto posterior comprende un cuerpo, una pluralidad de primeros puntos de soldadura y una pluralidad de segundos puntos de soldadura; la pluralidad de primeros puntos de soldadura y la pluralidad de segundos puntos de soldadura están situadas a cada lado del cuerpo en la dirección de la anchura; cada uno de los primeros puntos de soldadura se extiende hacia fuera desde un lado del cuerpo; cada uno de los segundos puntos de soldadura se extiende hacia fuera desde el otro lado del cuerpo; los primeros puntos de soldadura y los segundos puntos de soldadura tienen formas diferentes; y/o, las líneas centrales de al menos un grupo de los primeros puntos y los segundos puntos de soldadura adyacentes están escalonadas en la dirección de la anchura del cuerpo. De esta manera, se pueden absorber mejor las tensiones de expansión y contracción por la deformación de la tira de soldadura de forma especial para conexión de células de contacto posterior, minimizando así los daños por tensión a la célula solar.
