RECENT DEVELOPMENTS IN DYE SOLAR CELLS AT 3GSOLAR by Dr. Jonathan Goldstein, Dr. Ilya Yakupov and Barry Breen ABSTRACT: Dye solar cells (DSCs) offer a cheaper alternative to conventional silicon cells on the basis of 1. bill of materials (bulk titania powder is the photoactive material in place of silicon) and 2. process costs (screen printing and oven treatment in air in place of vacuum deposition). Furthermore, small research dye cells have been reported by various developers having promising energy conversion efficiencies of more than 10% under one sun illumination. Many developmental dye cells, however, have scale up, efficiency and stability limitations that have hindered commercialization. According to the approach of 3GSolar Ltd. (formerly Orionsolar Ltd.) here described, a novel, intrinsically corrosion-resistant, robust current collecting grid has been developed that allows scale-up to large area dye cells having increased stability and with reduced wastage of cell active area. Our prototype dye cells, which are glass based and have been scaled up to a full commercial single cell size of 225 sq cm, presently give 5.2% efficiency under one sun. We are steadily ramping up cell efficiency and durability by optimization of titania and other cell components, and are on schedule towards pilot production of cells and modules by the end of 2008. In this paper preliminary results are presented on the scale-up, fabrication and performance of full size prototype glass-based single dye cells of size 225 sq cm that incorporate the corrosion-resistant robust current collectors.

FLASH: OBAMA HIRES GONO: WALL STREET SEZ: OH NO!! MAIN STREET SEZ: DON'T STEP IN THE UNGAWA The governor of Zimbabwe's Reserve Bank, Dr. Gideon Gono, was appointed today by President-elect Obama to head up a special emergency financial stimulus team. Gono, in a prepared statement, indicated that it would take no less than $US 1000 quadrillions to right what's wrong with the US, the preeminent model of free market capitalism. "I have beheld the mystic hand of the free market spirit, and it has raised its sacred finger to us. We in Zimbabwe have been inspired and we bring our gifts of wisdom to President Obama." American Keynesians, formerly enlisted as advisers to the Obama team and whose stimulus packages were deemed inadequate, headed home with their tails between their legs. OB was seen waving goodbye to them after emerging from a basement print shop while wiping ink stains from his hands.
