| 摘要 |
A solar cell structure includes a silicon crystal having at least one slant penetrating hole, the penetrating hole internally having at least one inclined surface; an emitter covering the silicon crystal and the inclined surface in the penetrating hole; and a first metal electrode being electrically connected to the emitter and located in the penetrating hole of the silicon crystal at a bottom thereof. By forming the inclined surface having an inclination angle in the slant penetrating hole, light incident upon the inclined surface of the penetrating hole can have a length-increased optical path in the solar cell to thereby enhance the photocurrent of the solar cell.
