Abstract:
The present invention relates to a tandem solar cell combined with an amorphous silicon solar cell and an organic solar cell. A transparent conducting intermediate layer is formed at an interface between the amorphous silicon solar cell and the organic solar cell. The loss of light absorption due to the introduction of the transparent conducting intermediate layer is minimized and the interface resistance of the inner part of the tandem solar cell is greatly reduced. Thereby, a solar cell of high efficiency can be manufactured.
