Abstract
The present disclosure relates to a composition that includes a silicon layer having a first surface and a ZnTiN2 layer having a second surface, where the first surface and the second surface are physically in contact, and the composition is capable of photovoltaic properties when irradiated with light having a wavelength less than 1200 nm.
Claims20
A composition comprising:
- a silicon layer having a first surface;
- and
- a ZnTiN2 layer having a second surface, wherein:
- the first surface and the second surface are physically in contact, and
- the composition is capable of photovoltaic properties when irradiated with light having a wavelength less than 1200 nm.
2 more elements
A device comprising:
- a composition comprising:
- a silicon layer having a first surface;
- an oxide layer;
- and
- a ZnTiN2 layer having a second surface;
- and
- an electrolyte, wherein:
- the device is at least partially immersed in an electrolyte, and
- the oxide layer is positioned such that the oxide layer can be irradiated with light.
6 more elements
A method utilizing a device, the method comprising:
- contacting the device with an electrolyte having a pH between 2 and 12;
- irradiating the device with light;
- and
- generating a photovoltage that is substantially independent of the solution potential of a redox couple in the electrolyte.
