Claim 0:
1. A photoelectric chip, which is a back-incident photoelectric chip, wherein the chip is provided with a light-splitting groove, and the light-splitting groove runs through an absorption layer of the chip; and
a back of the chip is a light-entering side; the light-splitting groove is configured to transmit and split out one part of incident light, and the other part of the incident light enters the absorption layer for photovoltaic conversion,
wherein the chip further comprising:
a top layer, wherein the top layer is located on one side of a front of the absorption layer; the light-splitting groove is open in a direction away from the back of the chip and runs through the top layer, and a photosensitive area of the chip is formed in the top layer; an inner end of the photosensitive area is connected to the absorption layer, and an outer end of the photosensitive area is connected to a first electrode of the chip; the photosensitive area corresponds to an area in the absorption layer for performing photoelectric conversion; and the first electrode is located on the front of the chip.
