Charge Separation at Self-Assembled Nanostructured Bulk Interface in Block Copolymers

Proper percolation of charges in solar cells is possible with the self‐assembled nanostructure of a block‐copolymer film (see the TEM cross section of a solar cell). A photovoltaic device made from such a block copolymer exhibits a ten‐times higher short circuit current and a considerably larger pho...

Zusammenfassung:Proper percolation of charges in solar cells is possible with the self‐assembled nanostructure of a block‐copolymer film (see the TEM cross section of a solar cell). A photovoltaic device made from such a block copolymer exhibits a ten‐times higher short circuit current and a considerably larger photovoltage than its polymer‐blend analogue.
