1. A roof panel having a solar cell of a vehicle in which heterogeneous solar cells are disposed in a roof glass, comprising: (5) (5)

a first solar cell configured to be mounted at a central portion of the roof glass; and

a second solar cell having transparency lower than that of the first solar cell configured to be mounted at an edge portion of the roof glass,

wherein upper and lower surfaces of the first solar cell and the second solar cell are sequentially stacked with a bonding film and the roof glass,

at least one of the first solar cell and the second solar cell is configured of a plurality of cells and the plurality of cells of the solar cell are connected in series and in parallel so that output voltages of the solar cells are the same, and

the first solar cell and the second solar cell are adjacently positioned to each other, maintaining a gap to prevent the first solar cell and the second solar cell from contacting each other.

2. The roof panel of claim 1, wherein the first solar cell and the second solar cell are formed of different thicknesses and further include filling films to offset a difference in thickness between the first solar cell and the second solar cell. (0)

3. The roof panel of claim 1, wherein in the case of the solar cell configured of the plurality of cells, the cells have the same size. (0)

4. The roof panel of claim 1, wherein the first solar cell is selected from the group consisting of: a dye-sensitive solar cell, an amorphous silicon solar cell, an organic solar cell, a perovskite-based solar cell, a quantum dot solar cell, and combination of at least two thereof. (0)

5. The roof panel of claim 1, wherein the second solar cell is selected from the group consisting of: a crystalline silicon solar cell, a cadmium-telluride (CdTe) solar cell, a copper-indium-gallium-selenium (CIGS) solar cell, and a combination of at least two thereof. (0)

6. The roof panel of claim 1, wherein a constant gap between the first solar cell and the second solar cell is filled with an insulator. (0)

7. A roof panel having a solar cell of a vehicle in which heterogeneous solar cells are disposed in a roof glass, comprising: (6) (7)

a first solar cell configured to be mounted at a central portion of the roof glass;

a second solar cell having transparency lower than that of the first solar cell configured to be mounted at an edge portion of the roof glass;

a first electric wire part configured to be connected to an electrode of the first solar cell;

a second electric wire part configured to be connected to an electrode of the second solar cell; and

a plurality of controllers configured to be connected to the first electric wire part and the second electric wire part, respectively,

wherein upper and lower surfaces of the first solar cell and the second solar cell are stacked with a bonding film, and

the first solar cell and the second solar cell are adjacently positioned to each other, maintaining a gap to prevent the first solar cell and the second solar cell from contacting each other.

8. The roof panel of claim 7, wherein the plurality of controllers control a connection between a charger and a driver depending on outputs of the solar cells. (0)

9. The roof panel of claim 7, wherein at least one of the plurality of controllers receives information measured by a positional information sensor of the vehicle which measures positional information of the sun, a geomagnetic sensor which measures a slope of the vehicle, and a tilt sensor which measures a slope of the roof panel and controls the slope of the roof channel depending on the received information. (0)

10. The roof panel of claim 7, wherein at least one of the plurality of controllers is configured of a maximum power point tracking (MPPT) controller. (0)

11. The roof panel of claim 7, wherein the first solar cell is selected from the group consisting of: a dye-sensitive solar cell, an amorphous silicon solar cell, an organic solar cell, a perovskite-based solar cell, a quantum dot solar cell, and a combination of at least two thereof. (0)

12. The roof panel of claim 7, wherein the second solar cell is selected from the group consisting of: a silicon solar cell, a cadmium-telluride (CdTe) solar cell, a copper-indium-gallium-selenium (CIGS) solar cell, and a combination of at least two thereof. (0)

13. The roof panel of claim 7, wherein a constant gap between the first solar cell and the second solar cell is filled with an insulator to prevent the first solar cell and the second solar cell from contacting each other. (0)
