The present invention relates specific activation of a regulatory T cell via a specific CD4 epitope and uses thereof, e.g. for the treatment of an autoimmune disease or an allergy or asthma or graft rejection or tolerance induction.

Screening method for the identification of agents capable of activating CD4+CD25+ regulatory T-cells through interactions with the HIV-1 GP120 binding site on CD4

Methods are provided for fabricating photovoltaic cell contacts, which include: providing a block copolymer layer above an electrical contact layer of the photovoltaic cell, the block copolymer layer being self-assembled by phase segregation to include multiple structures of a first polymer material surrounded, at least in part, by a second polymer material; selectively etching the block copolymer layer to remove the multiple structures, forming holes in the block copolymer layer; and using the holes in the block copolymer layer to facilitate providing electrical contacts between a light absorption layer of the photovoltaic cell and the electrical contact layer. For instance, the holes in the copolymer layer may be used in etching a passivation layer over the electrical contact layer to form nano-sized contact openings in the passivation layer to the contact layer. Once provided, the cell's light absorption material forms contacts extending through the contact openings in the passivation layer.

Fabrication of thin-film photovoltaic cells with reduced recombination losses

A method for manufacturing a solar concentrator cell module assembly within an integrated circuit process, which solar concentrator cell module assembly includes at least one solar device and which solar device includes one printed circuit board and one Fresnel lens. A printed circuit board is assembled according to a pre-defined circuit board base design layout that allows pick and place of a single solar concentrator cell chip onto a circuit board base. Connections are provided for the solar concentrator cell chip in a serialized or a parallelized arrangement on the circuit board base, and a plurality of openings are formed in the circuit board base below a backside of the solar concentrator chip to enable attachment of cooling fingers. A solar device based on a solar device layout is assembled using the assembled circuit board base and one Fresnel lens, the solar device having a solar concentration ratio by modifying the solar device surface versus the solar cell surface and covering a full extension of the circuit board base, which circuit board base provides means for interconnecting a plurality of the solar devices to one another to form the solar concentrator cell module assembly.
