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..The present disclosure relates to a photovoltaic cell and a photovoltaic module. The photovoltaic cell comprises a substrate, a passivation layer arranged on at least one surface of the substrate, at least one busbar (1) and at least one finger (2), each of which intersects on the surface of the substrate, and at least one soldering pad (3 ) arranged on a surface of the substrate. The at least one busbar (1) is electrically connected to the at least one finger (2). The number of soldering pads (3) is 2 to 6. The at least one soldering pad (3) comprises first soldering pads (31), and the first soldering pads (31) are arranged at two ends of one of the at least one busbar (1). A number of at least one busbar (1) is greater than or equal to 11, and the at least one busbar each has a width of 20 μm to 80 μm. The at least one finger each has a width of 20 μm to 80 μm, and the number of fingers is 70 to 160. The at least one first soldering pad (31) each has a length and a width in a range from 0.3 mm to 1.2 mm on. This design can reduce the shielding of the substrate and facilitate the light absorption of the photovoltaic cell. At the same time, increasing the number of busbars and reducing the current flowing through a single busbar can reduce internal losses, and reducing the area of the solder pad can reduce silver paste consumption and help reduce costs to more closely meet actual usage needs. .
