Abstract: Back reflector arrays are applied to the surface distal to the incident light receiving surface of a thin film solar cell to increase its efficiency by altering the reflected light path and thereby increasing the path length of light through the active layer of the solar cell. The back reflector is an array of features of micrometer proportions. The feature may be concave or convex features such as hemispheres, hemi-ellipsoids, partial-spheres, partial-ellipsoids, or combinations thereof The feature may be pyramidal. A method of forming the back reflector array is by forming an array of features from a photocurable resin, subsequent curing the resin and metalizing the cured resin to render the surface reflective. The photocurable resin can be applied by inkjet printing or rolling or stamping with a mold.

Abstract: Textured transparent layers are formed on the incident light receiving surface of thin film solar cells to increase their efficiency by altering the incident light path and capturing a portion of the light reflected at the MLA. The textured transparent layer is an array of lenses of micrometer proportions such as hemispheres, hemi-ellipsoids, partial-spheres, partial-ellipsoids, cones, pyramids, prisms, half cylinders, or combinations thereof. A method of forming the textured transparent layer to the light incident surface of the solar cell is by forming an array of lenses from a photocurable resin and its subsequent curing. The photocurable resin can be applied by inkjet printing or can be applied by roll to roll imprinting or stamping with a mold.

Abstract: Embodiments of the invention pertain to the use of alloyed semiconductor nanocrystals for use in solar cells. The use of alloyed semiconductor nanocrystals offers materials that have a flexible stoichiometry. The alloyed semiconductor may be a ternary semiconductor alloy, such as AxB1-xC or AB1-yCy, or a quaternary semiconductor alloy, such as AxByC1-x-yD, AxB1-xCyD1-y or ABxCyD1-x-y (where A, B, C, and D are different elements). In general, alloys with more than four elements can be used as well, although it can be much harder to control the synthesis and quality of such materials. Embodiments of the invention pertain to solar cells having a layer incorporating two or more organic materials such that percolated paths for one or both molecular species are created. Specific embodiments of the invention pertain to a method for fabricating nanostructured bulk heterojunction that facilitates both efficient exciton diffusion and charge transport. Embodiments of the subject invention pertain to a solar cell having an architecture that allows for efficient harvesting of solar energy. The organic solar cell architecture can incorporate a host/guest (or matrix/dopant) material system that utilizes the long diffusion lengths for triplet excitons without compromising light absorption efficiency.

Abstract: Embodiments of the invention are directed to quantum dot light emitting diodes (QD-LEDs) where the electron injection and transport layer comprises inorganic nanoparticles (I-NPs). The use of I-NPs results in an improved QD-LED over those having a conventional organic based electron injection and transport layer and does not require chemical reaction to form the inorganic layer. In one embodiment of the invention the hole injection and transport layer can be metal oxide nanoparticles (MO-NPs) which allows the entire device to have the stability of an all inorganic system and permit formation of the QD-LED by a series of relatively inexpensive steps involving deposition of suspensions of nanoparticles and removing the suspending vehicle.
