TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Cell: The solar cell comprises: a quantum dot; an electron conductor; a conjugated bridge molecule disposed between the quantum dot and the electron conductor, where the conjugated bridge molecule comprises a first anchor group bonded to the quantum dot and a second anchor group bonded to the electron conductor; and a hole conductor configured to reduce the quantum dot once the quantum dot absorbs a photon and ejects an electron through the conjugated bridge molecule and into the electron conductor. Preferred Light Assembly: In the assembly, the quantum dot anchor comprises a first quantum dot anchor group and a second quantum dot anchor group, where the first quantum dot anchor group and the second quantum dot anchor group form a ring structure in combination with the conjugated bridge molecule and a bonding site on the quantum dot, and each of the first quantum dot anchor group and the second quantum dot anchor group independently comprise a thiol moiety or an amine moiety. The electron conductor anchor comprises a first electron conductor anchor group and a second electron conductor anchor group, where the first electron conductor anchor group and the second electron conductor group form a ring structure in combination with the conjugated bridge molecule and a bonding site on the electron conductor, and each of the first electron conductor anchor group and the second electron conductor anchor group independently comprise a carboxylic acid moiety or a phosphonic acid moiety. Preferred Components: The electron conductor layer comprises an n-type semiconductor. The hole conductor comprises a conductive polymer, an electrolyte or a p-type conductor.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The conjugated bridge molecule layer comprises several conjugated bridge molecules, where at least some of the conjugated bridge molecule comprises a first anchor group bonded to at least one of the quantum dots and a second anchor group bonded to the electron conductor layer. The conjugated bridge molecules are formed by adding quantum dot anchor functionality to at least one of catechol, methyl catechol, tert-butyl catechol or benzothiazole-2-thiol. SPECIFIC COMPOUNDS - 13 Compounds are specified as the conjugated bridge molecules, e.g. 4,5-disulfanylanthracene-1,8-dicarboxylic acid (IA); 1,2-dihydroxy-anthraquinone; 3,4-dihydroxybenzylamine; 3,4-dihydroxy-cyclobut-3-ene-1,2-dione; and 3-mercaptoacrylic acid.
