Abstract:
The present invention relates to an amorphous silicon solar cell that includes an upper/lower electrode and an interfacial electrode applying an electric field between light absorption layers without a doping process. Because a doping process is not carried out, a harmful doping gas is not used. Also, because a window layer for receiving light is used as a metallic oxide which has high light transmission and a function of transferring holes, the loss of light reaching a light absorption layer can be minimized and the photocurrent density improved.
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.
