摘要:在过去的20年中,基于钌(II)的染料在将染料敏化太阳能电池(dsc)转变为第三代光伏产品的成熟技术方面发挥了关键作用.但是,经典的i 3-/ I-氧化还原对限制了该技术的性能和应用.由于钌(II)敏化剂与钴氧化还原物质之间的相容性差,仅用新型的钴(3 + / 2 +)络合物取代基于碘的氧化还原对就不成功.为了解决此问题并实现更高的功率转换效率(pce),我们在此介绍通过配体工程开发的六种新的基于环金属化钌(II)的染料.我们测试了使用这些钌(II)配合物的dsc,并使用基于钴(3 + / 2 +)的电解质实现了高达9.4%的pce,这是迄今为止基于钌的染料的记录效率.鉴于复杂的液体dsc系统,在不同表征之间发现的分歧使我们意识到了tio2上敏化剂负载的重要性2,这是敏化剂电子特性中的一个微妙但同样重要的因素.

标题 :Branch point effect on structure and electronic properties of conjugated polymers
发明人：BRIDGES COLIN R; WANG MING; FORD MICHAEL J; BAZAN GUILLERMO C; SEGALMAN RACHEL A
权利人:UNIV CALIFORNIA
摘要:Synthesis of lyotropic semiconducting polymers having novel side chains enabling control over crystalline fraction, crystalline orientation, and the unit cell (specifically the Ï€-stacking distance). Moving the branch point in the side chain further from the conjugated backbone not only retains the lyotropic liquid crystalline behavior as observed by UV-vis and POM, but also achieves reduced Ï€-stacking distance. This results in higher charge carrier mobility, reaching (in one or more examples) a mobility of at least 0.41 cm 2 V −1 s −1 when the polymers were non-aligned.

摘要:Copolymers of formula (I): n nwhere each A is S, Se or Câ•?C; each x is an integer from 1 to 4; each R1 is independently H, F, CN or a C 1 -C 20 linear or branched aliphatic group; Ar is one or more substituted or unsubstituted aromatic units; and, n is an integer 5 or greater, can be formed into films or membranes that are useful as active layers in organic electronic device, such as PV solar cells, providing high power conversion efficiencies and good thermal stability. Such copolymers may be synthesized from monomers of formula (II):n n nby Stille or Suzuki coupling reactions. Such monomers may be synthesized by a variation of the Pinner synthesis.

摘要:Photoactive compositions of matter, methods for their design and synthesis, and various applications of such compositions of matter are disclosed. Such photoactive compositions may, for example, include any one or more of the following: a core moiety; a primary electron donor moiety; an electron-withdrawing moiety; and an alkyl tail. Some photoactive compositions may further include multiple additional electron donor moieties, electron-withdrawing moieties, and alkyl tails. Methods for designing such photoactive compositions may include selecting a core moiety; selecting an electron-withdrawing moiety to add to the core moiety in order to modify the composition's electronic properties; selecting a primary electron donor moiety to be added in order to further modify the composition's electronic properties; selecting a second electron donor moiety to be added in order to modify the composition's electronic properties even further, if necessary; and synthesizing the designed composition.
