Sep. 1, 2005 — Solaris Nanosciences of Providence, R.I., has demonstrated what it claims to be a completely rechargeable dye sensitized solar cell (also known as a Graetzel cell).
The recharging process and its performance were independently confirmed at the Swiss Federal Institute of Technology Lausanne where dye sensitized solar cells were invented by Professor Michael Graetzel.
Graetzel said in a prepared statement that the cell’s performance remained intact after three cycles. He added that the procedure is the first to accomplish a rapid and complete replenishment of the sensitizer and electrolyte. Graetzel is on the science advisory board of Solaris Nanosciences.
Solaris says it plans to develop a large scale prototype of its rechargeable solar cell for testing at the National Renewable Energy Laboratory and with corporate partners to explore the distribution of the technology through the building and construction industry.
