    • Provided is a collector sheet for a solar cell, and contributing to improvement of power generation efficiency. A collector sheet (5) for a solar cell is disposed on the rear surface side of a solar cell element (4), and is provided with: a circuit (54), which is formed on the front surface of a resin base material (53), and which is configured of a wiring section (541) composed of a metal, and a non-wiring section (542); and an insulating layer (52), which is formed on the circuit (54). Light extraction to the solar cell element (4) due to reflection from the insulating layer (52) is increased, said insulating layer being disposed at the element periphery of the solar cell element (4), by having a white pigment contained in the insulating layer (52), and power generation efficiency is improved even in a back contact solar cell element.
    • 提供一种太阳能电池用集电体片,有助于提高发电效率。 在太阳能电池元件(4)的背面侧配置有用于太阳能电池的集电片(5),并且设置有形成在树脂基材的表面上的电路(54) 53),由金属构成的配线部(541)和非配线部(542)构成。 以及形成在电路(54)上的绝缘层(52)。 由于绝缘层(52)的反射而向太阳能电池元件(4)的光提取增加,所述绝缘层通过在绝缘层(52)中包含白色颜料而设置在太阳能电池元件(4)的元件周围 层(52),即使在背接触太阳能电池元件中也能够提高发电效率。
