Abstract

A photovoltaic cell comprises a membrane electrode assembly obtainable by the in situ polymerisation between two electrodes of one or more monomers to form a polymer, and then infusing an activating agent into the polymer, wherein the activating agent enables the membrane electrode assembly to function as a photovoltaic cell.

Claims

exact text as granted — not AI-modified
1 . A photovoltaic cell comprising a membrane electrode assembly obtainable by the in situ polymerisation between two electrodes of one or more monomers to form a polymer, and then infusing an activating agent into the polymer, wherein the activating agent enables the membrane electrode assembly to function as a photovoltaic cell. 
     
     
         2 . The cell according to  claim 1 , wherein the membrane comprises a hydrophilic polymer. 
     
     
         3 . The cell according to  claim 1 , comprising adding a redox mediator to the one or more monomers to be polymerised. 
     
     
         4 . The cell according to  claim 1 , wherein the mediator is added immediately prior to the polymerisation. 
     
     
         5 . The cell according to  claim 1 , wherein the activating agent is an oxidant or a reductant. 
     
     
         6 . The cell according to  claim 1 , wherein the activating agent is atmospheric oxygen. 
     
     
         7 . The cell according to  claim 1 , wherein the activating agent is hydrogen peroxide. 
     
     
         8 . The cell according to  claim 1 , wherein the activating agent is dimethyl sulfoxide (DMSO). 
     
     
         9 . The cell according to  claim 1 , wherein the activating agent is an electrolyte. 
     
     
         10 . The cell according to  claim 9 , wherein the electrolyte is a dye-sensitized solar cell electrolyte. 
     
     
         11 . The cell according to  claim 1 , wherein the activating agent is a redox mediator. 
     
     
         12 . The cell according to  claim 3 , wherein at least one of the mediators is iodide. 
     
     
         13 . The cell according to  claim 3  wherein at least one of the mediators is iodine. 
     
     
         14 . The cell according to  claim 3  wherein at least one of the mediators is tri-iodide. 
     
     
         15 . The cell according to  claim 3 , wherein the mediator that is added to the one of more monomers to be polymerised is one half of a redox couple, and wherein the activating agent is the corresponding other half of the redox couple. 
     
     
         16 . The cell according to  claim 15 , wherein the one half of a redox couple is iodide and the other half of the redox couple is iodine. 
     
     
         17 . The cell according to  claim 15 , wherein the redox couple is iodide/oxygen. 
     
     
         18 . The cell according to  claim 1 , wherein one electrode is a dye-sensitised nanoporous semi-conductor and the other electrode is a catalyst-coated counter electrode. 
     
     
         19 . The cell according to  claim 1 , wherein the polymerisation is photo-initiated.
