Abstract: Improved reaction processes comprise reacting a mixture to form a product comprising a metal alkyl, metal oxide, or mixture thereof and then passing said product to a post-reactor heat exchanger. The improvement comprises one or more of the following: (1) reacting said metal alkyl compound with an acid to produce a soluble metal ester; or (2) adding an ionic surfactant; or (3) adding a mixture comprising an antioxidant to the product under conditions sufficient to avoid formation of significant amounts of insoluble metal or metal compounds derived from said metal alkyl compound; or (4) purging said post-reactor heat exchanger with an inert gas under conditions to remove metal oxide from the post-reactor heat exchanger.

Abstract: The invention relates to a photovoltaic article comprising a plurality of photovoltaic cells having first (22) and second (24) electrical connector segments in contact with the top side (18) of a first cell (10) and the backside (16) of a second adjacent cell (12). The materials used to form the electrical connector segments are selected to minimize corrosion, maximize contact area, and lower contact resistance over the lifetime of the article.

Abstract: An article of manufacture includes a PV element having a conductive layer positioned on a light-incident side of the PV element, a conductor electrically coupled to the conductive layer, and a conductive particle matrix interposed between the conductor and the conductive layer at a number of positions on the conductive layer. The article further includes a carrier film positioned on the light-incident side of the PV element, and a non-conductive adhesive, where the adhesive and the conductor are positioned between the carrier film and the conductive layer.

Abstract: An article of manufacture (400) includes a number of photovoltaic cells (102) forming a photovoltaic (PV) module circuit, with a first bus bar (106) electrically coupled to one extremity of the PV module circuit and a second bus (206) bar electrically coupled to a second extremity of the PV module. The bus bars (106, 206) are positioned on an opposing side of the PV cells (104, 204) from a light incident side of the PV cells.
