Abstract
A photovoltaic device includes a heterojunction between different semiconductor materials which are present in charge transporting layers. The charge transporting layer can be a hole or electron transporting layer. The device can include an interstitial layer between two layers of the device.
Claims21
A photovoltaic device comprising:
- a first charge transporting layer in contact with a first electrode arranged to introduce charge in the first charge transporting layer;
- a second charge transporting layer in contact with a second electrode arranged to introduce charge in the second charge transporting layer;
- and
- a first interstitial layer intermediate the first charge transporting layer and the second charge transporting layer.
1 more element
A method of making a device, comprising:
- depositing a first charge transport layer over an electrode;
- depositing a cascade material over the first charge transport layer, wherein the cascade material is in electrical contact with the first charge transport layer;
- and
- depositing a second charge transport layer over the electrode, wherein the cascade material is in electrical contact with the second charge transport layer.
