Abstract: A substrate carrier for solar cells, utilized in a wet etching process, comprising: two side plates; at least a side rod, connected respectively to an outer portion on each side of the two side plates; at least a bottom rod, connected respectively to a lower portion on each side of the two side plates; at least a press rod, connected respectively to an upper portion on each side of the two side plates. Wherein, a space formed by formed by the two side plates, the side rod, the bottom rod, and press rod, is used to receive at least a solar cell substrate. Wherein, a plurality of first teeth are arranged axially along axes of the side rod and the press rod, such that each of the first teeth maintains a point-to-point contact with each of the solar cell substrates.
