Solar PV Innovation:Does this new and innovative study effectively highlight the advantages of speeding up the movement of oxidized electrolytes in a dye-sensitized solar cell for improved efficiency?
As previously reviewed on this blog, dye-sensitized solar cells manufactured to mimic the process of photosynthesis, can be low-cost. They can also be very beneficial in producing hydrogen and oxygen when coupled with catalysts. Published by researchers at Stockholm's KTH Royal Institute of Technology in the Royal Society of Chemistry's journal, Physical Chemistry Chemical Physics--the research claims this process makes solar cells more energy efficient and long lasting.
"We now have clear evidence that by adding the ion-conducting polymer to the solar cell's cobalt redox electrolyte, the transport of oxidized electrolytes is greatly enhanced. The fast transport increases solar cell efficiency by 20 percent. Speeding up this transport is important because when slowed down, more of the cobalt complexes react with electrons in the semiconductor anode instead of with the electrons at the cathode, resulting in rapid recombination losses. Speeding up the cobalt lowers resistance and increases voltage and current in the solar cell." Said James Gardner, Assistant Professor of Photo-electro-chemistry at KTH, and part of the research team (reference).
Dye-sensitized solar cells are increasingly being interesting--Do you think its going to be our ticket to a more efficient solar cell?
