As such compounds, biphenyl derivatives with ferrocenyl and fluorine-containing germyl substituents have been studied in the present work. The DFT and TD-DFT methods (B3LYP, CAM-B3LYP, PBE0, wB97XD) have been used to study the structures and energies of excited states of these derivates and to estimate the exciton binding energies in materials based on them in vacuum and condensed matter. For a number of compounds, the obtained exciton binding energies are close to zero, and in a separate case even less than zero, which demonstrates the prospect of their synthesis and use.</p></abstract><trans-abstract xml:lang="ru"><p>Для повышения КПД органических фотовольтаических устройств необходим поиск новых перспективных соединений, обеспечивающих эффективное разделение зарядов при поглощении в оптической области спектра. В качестве таких соединений в настоящей работе исследованы производные бифенила с ферроценильными и фторсодержащими гермильными заместителями. Методами DFT и TD-DFT (B3LYP, CAM-B3LYP, PBE0, wB97XD) исследованы структуры и энергии возбужденных состояний этих производных и оценены энергии связи экситона в материалах на их основе в вакууме и конденсированной среде. Для ряда соединений полученные значения энергий связи экситона близки к нулю, а в отдельном случае даже меньше нуля, что указывает на перспективность их синтеза и использования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>ferrocene</kwd><kwd>germanium</kwd><kwd>DFT</kwd><kwd>photoinduced transition</kwd><kwd>exciton</kwd><kwd>photovoltaics</kwd><kwd>organic solar cells</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ферроцен</kwd><kwd>германий</kwd><kwd>DFT</kwd><kwd>фотоиндуцированный переход</kwd><kwd>экситон</kwd><kwd>фотовольтаика</kwd><kwd>органические солнечные элементы</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source><award-id>FSWR-2023-0024</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Milichko V.A., Shalin A.S., Mukhin I.S. et al. // Usp.
