Abstract
Photo-active devices including a substrate, a first electrode, an active layer including an organic salt or salt mixture that selectively or predominantly harvests light from the near infrared or infrared regions of the solar spectrum, and a second electrode. The devices are either visibly transparent or visibly opaque and can be utilized in single- or multi-junction devices.
Claims20
A photovoltaic device comprising:
- a first electrode;
- a second electrode;
- and
- an active layer comprising an organic semiconductor positioned between the first electrode and the second electrode,
- wherein the photovoltaic device has an open circuit voltage that is within 30% of the excitonic limit.
2 more elements
A photovoltaic device comprising:
- a first electrode;
- a second electrode;
- and
- an active layer positioned between the first electrode and the second electrode, the active layer comprising:
- a first organic salt having an ion and a first counterion;
- and
- a second organic salt having the same ion as the first organic salt and a second counterion, the second counterion being different from the first counterion.
4 more elements
A method of manufacturing a photo-active device, the method comprising:
- disposing an active layer between a first electrode and a second electrode,
- wherein the active layer comprises an organic salt comprising a counterion selected from the group consisting of halides, aryl borates, carboranes, phosphates, fluoroantimonates, fluoroborates, derivatives thereof, and combinations thereof, wherein the phosphates do not include fluorophosphates, and
- wherein the active layer harvests light.
