高分求英语paraphrase(改写)
An electrical current generated in the semiconductor is extracted by contacts to the front and rear of the cell.The top contact structure which must allow light to pass through is made in the form of widely-spaced thin metal strips that supply current to a larger bus bar.Solar cells are essentially semiconductor junctions under illumination.Light generates electron-hole pairs on both sides of the junction,in the n-type emitter and in the p-type base.The generated electrons (from the base) and holes (from the emitter) then diffuse to the junction and are swept away by the electric field,thus producing electric current across the device.
这儿也有积分,把这段话也paraphrase一下吧!
