Abstract

Die vorliegende Offenbarung bezieht sich auf eine photovoltaische Zelle und ein photovoltaisches Modul. Die photovoltaische Zelle umfasst ein Substrat, eine Passivierungsschicht, die auf mindestens einer Oberfläche des Substrats angeordnet ist, mindestens eine Busbar (1) und mindestens ein Finger (2), die sich jeweils auf der Oberfläche des Substrats überschneiden, und mindestens ein Lötpad (3), das auf einer Oberfläche des Substrats angeordnet ist. Die mindestens eine Busbar (1) ist mit dem mindestens einen Finger (2) elektrisch verbunden. Eine Anzahl der Lötpads (3) beträgt 2 bis 6. Das mindestens eine Lötpad (3) umfasst erste Lötpads (31), und die ersten Lötpads (31) sind an zwei Enden einer der mindestens einen Busbar (1) angeordnet. Eine Anzahl von mindestens einem Busbar (1) ist größer als oder gleich 11, und die mindestens eine Busbar weist jeweils eine Breite von 20 μm bis 80 μm auf. Der mindestens eine Finger weist jeweils eine Breite von 20 μm bis 80 μm auf, und eine Anzahl der Finger beträgt 70 bis 160. Das mindestens eine erste Lötpad (31) weist jeweils eine Länge und eine Breite in einem Bereich von 0.3 mm bis 1.2 mm auf. Dieses Design kann die Abschirmung des Substrats reduzieren und die Lichtabsorption der Photovoltaikzelle erleichtern. Gleichzeitig können eine Erhöhung der Anzahl der Busbars und eine Verringerung des Stroms, der durch eine einzelne Busbar fließt, interne Verluste reduzieren, und eine Verringerung der Fläche des Lötpads kann den Verbrauch an Silberpaste reduzieren und zur Kostensenkung beitragen um den tatsächlichen Nutzungsanforderungen eher zu entsprechen..
