International Classification:

H01L 31/00

US Classification:

136256

Abstract:

Described herein are photovoltaic devices including self-assembling fullerene derivatives. In one embodiment, a photovoltaic device includes a first electrode layer, a second electrode layer, and an active layer disposed between the first electrode layer and the second electrode layer. The active layer is configured to absorb incident light to produce a first type of charge carrier that is transported to the first electrode layer and a second type of charge carrier that is transported to the second electrode layer. The active layer includes self-assembled molecules of a fullerene derivative to provide a conductive path through at least a portion of the active layer.

International Classification:

H01G 9/155

US Classification:

361502

Abstract:

A mesoporous, nanocrystalline, metal oxide construct particularly suited for capacitive energy storage that has an architecture with short diffusion path lengths and large surface areas and a method for production are provided. Energy density is substantially increased without compromising the capacitive charge storage kinetics and electrode demonstrates long term cycling stability. Charge storage devices with electrodes using the construct can use three different charge storage mechanisms immersed in an electrolyte: (1) cations can be stored in a thin double layer at the electrode/electrolyte interface (non-faradaic mechanism); (2) cations can interact with the bulk of an electroactive material which then undergoes a redox reaction or phase change, as in conventional batteries (faradaic mechanism); or (3) cations can electrochemically adsorb onto the surface of a material through charge transfer processes (faradaic mechanism).

Abstract:

A lithium ion battery that incorporates an anode formed from a Group IV semiconductor material such as porous silicon is disclosed. The battery includes a cathode, and an anode comprising porous silicon. In some embodiments, the anode is present in the form of a nanowire, a film, or a powder, the porous silicon having a pore diameters within the range between 2 nm and 100 nm and an average wall thickness of within the range between 1 nm and 100 nm. The lithium ion battery further includes, in some embodiments, a non-aqueous lithium containing electrolyte. Lithium ion batteries incorporating a porous silicon anode demonstrate have high, stable lithium alloying capacity over many cycles.
