Abstract
A back contact solar cell includes a semiconductor substrate, a first functional layer, a second functional layer, a laser protection layer, a first electrode structure, and a second electrode structure. The semiconductor substrate has a light-receiving surface and a shady surface. The first functional layer is formed in the first polarity region. The second functional layer is formed in the second polarity region. The laser protection layer is formed on a side of the second functional layer away from the semiconductor substrate and exposes an electrode contact region of the second functional layer. The laser protection layer includes laser absorption material. The first electrode structure is formed on a side of the first functional layer away from the semiconductor substrate. The second electrode structure is formed on a side of the second functional layer away from the semiconductor substrate, and the second electrode structure is in the electrode contact region.
