Donor-acceptor DYAD compounds in photovoltaics

A method comprising:

• depositing a first electrode;
• forming a photoactive layer with a donor and an acceptor by depositing a dyad having a first moiety linked by a chemical bond to a second moiety, wherein arrangement and interspacing of the donor and the acceptor relative to one another is controlled once deposited by cleaving the chemical bond of the dyad between the first moiety that provides the donor and the second moiety that provides the acceptor;
• and
• depositing a second electrode to provide a photovoltaic cell with the photoactive layer disposed between the first and second electrodes;
• wherein the dyad has a formula that is
• and wherein the depositing of the dyad includes deposition of a polymer formed of the dyad as a monomer unit.

A device comprising:

• a first electrode;
• a second electrode;
• and
• a photoactive layer with a controlled arrangement and interspacing of a donor and an acceptor relative to one another disposed between the first and second electrodes to provide a photovoltaic cell, wherein the controlled arrangement and interspacing is based on separation at a cleaved chemical bond, which before cleavage linked within a dyad a first moiety that provides the donor with a second moiety that provides the acceptor;
