NOVELTY - The rectangular solar cell made of a crystalline material comprises a front side (6) that faces light and has a first polarity, a rear side that faces away from the light and has a second polarity, a bus that extends on its front side along a first longitudinal edge of the solar cell for collecting and transferring current formed on the solar cells, a bus that extends on its rear side along a second longitudinal edge of the solar cell for collecting and transferring current formed on the solar cells, and fingers (7), which are parallel, spaced apart and arranged on the front side of cell.    USE - Used as a solar cell.    ADVANTAGE - The solar cell exhibits high energy conversion efficiency and reduced power loss.    DETAILED DESCRIPTION - The rectangular solar cell made of a crystalline material comprises a front side (6) that faces light and has a first polarity, a rear side that faces away from the light and has a second polarity, a bus that extends on the front side of the solar cell along a first longitudinal edge of the solar cell for collecting and transferring current formed on the solar cells, a bus that extends on the rear side of the solar cell along a second longitudinal edge of the solar cell for collecting and transferring current formed on the solar cells, and fingers (7), which are parallel, spaced apart and arranged on the front side of solar cell, run perpendicular to the bus arranged on the front side and are electrically connected to the bus. The back side is designed as a full surface or as a net of metallic conductors, and is electrically connected with the bus. The solar cell has a length-to-width ratio of greater than or equal to 6, a length of greater than or equal to 150 mm, and a thickness of less than or equal to 300 mu m. The buses run at respective longitudinal edge of the solar cell without distance. An INDEPENDENT CLAIM is included for an arrangement of solar cells.
