This disclosure features an article that includes first and second electrodes, a photoactive layer between the first and second electrodes, and a hole carrier layer between the first electrode and the photoactive layer. The hole carrier layer includes a Cu(I)-containing material. The article is configured as a photovoltaic cell.

Photovoltaic cells

Replacing liquid electrolytes with solid or quasi-solid electrolytes facilitates the production of photovoltaic cells using continuous manufacturing processes, such as roll-to-roll or web processes, thus creating inexpensive, lightweight photovoltaic cells using flexible plastic substrates.

Gel electrolytes for dye sensitized solar cells

The invention, in one aspect, provides a photovoltaic cell including a charge carrier material and a photosensitized interconnected nanoparticle material including nanoparticles linked by a polymeric linking agent, both disposed between first and second rigid, significantly light-transmitting substrates. In one embodiment, the charge carrier material and the photosensitized interconnected nanoparticle material are disposed between a first and second flexible, significantly light-transmitting substrate that are themselves disposed between the first and second rigid, significantly light-transmitting substrates.

Photovoltaic cells incorporating rigid substrates

Photovoltaic materials and methods of photovoltaic cell fabrication provide a photovoltaic cell in the form of a fiber. These fibers may be formed into a flexible fabric or textile.

Photovoltaic fibers

Modules are disclosed. The modules can include: a first photovoltaic cell including an electrode; a second photovoltaic cell including an electrode; and an interconnect that connects the electrodes of first and second photovoltaic cells. The interconnect can include: an electrically insulative material adhesive material; and a mesh partially disposed in the adhesive material.

Photovoltaic module architecture

Modules are disclosed. The modules can include a first photovoltaic cell including an electrode; and a second photovoltaic cell including an electrode having a bent end connected to the electrode of the first photovoltaic cell.

A method of making a photovoltaic cell includes contacting a cross-linking agent with semiconductor particles, and incorporating the semiconductor particles into the photovoltaic cell.

Photovoltaic cell

Zwitterionic compounds, photovoltaic cell charge carrier layers containing such compounds, photovoltaic cells including such charge carrier layers, and related methods are disclosed.

Zwitterionic compounds and photovoltaic cells containing same

A polymeric linking agent enables the manufacture of photovoltaic cells on flexible substrates, including, for example, polymeric substrates. Photovoltaic cells may be fabricated by a relatively simple continuous manufacturing process, for example, a roll-to-roll process, instead of a batch process.

Low temperature interconnection of nanoparticles

The invention features a method of making a gradient-index polymer rod involving the steps of: combining a polymer with an additive, wherein the refractive index of the polymer material is different than the refractive index of the additive material; extruding the polymer and the additive into a polymer rod having a substantially uniform index of refraction profile; and immersing the rod having the substantially uniform index of refraction profile in a non-solvent under conditions and for a time that enables the non-solvent to permeate the rod and out-diffuse a portion of the additive material, thereby producing the gradient-index polymer rod. The rod produced by the method can be drawn into a graded index polymer fiber. The invention also features a gradient-index polymer rod (or fiber) of condensation-type polymer that is doped with an additive material. The refractive index of the additive material is different than the refractive index of the polymer and the rod (or fiber) has a concentration profile of the additive that varies along the radial direction of the rod (or fiber) from the center to the surface of the rod (or fiber).
