Title: gratzel cell
Post by: aadharmg on November 26, 2017, 04:10:45 pm
I need information on the chemistry part of the gratzel cell in electrochemistry. I honestly cannot find anything about the cell diagram or its anode-cathode reactions. Also for that dot point, are the reactions all I need to know for the chemistry part of the cells?

The reactions are hidden in my sheet under Jake's.

It may help to interpret the reactions with this video.

You will certainly need more than just the half-equations though. The dot point clearly states:

gather and present information on
the structure and chemistry of a dry
cell or lead-acid cell and evaluate it
in comparison to one of the
following:
– button cell
– fuel cell
– vanadium redox cell
– lithium cell
– liquid junction photovoltaic
device (eg the Gratzel cell)
in terms of:
– chemistry
– cost and practicality
– impact on society
– environmental impact
