Abstract
В данной работе описан и применен способ визуализации внутренней структуры фотоактивных слоев полимерных солнечных батарей методами сканирующей зондовой микроскопии, основанный на использовании ультрамикротома для получения срезов фотоактивного слоя . Данный метод позволяет использовать преимущества атомно - силовой микроскопии при изучении стру ктуры в объеме мягких образцов, такие как вы сокий контраст изображений и способность измерять различные свойства поверхности с нанометровым разрешением. Описанным методом и сследованы образцы фотоактивного слоя полимерной солнечной батареи на основе смеси производной тиофена PTB 7 и производной фуллер ена PC 71 BM . Обнаруж ены новые детали вн утренней структуры данной смеси, позволяющие сделать дополнительные выводы о механизме влияния добавок дий одооктана на эффективность солнечных элементов. A method for visualization via atomic-force microscopy of the internal structure of photoactive layers of polymer solar cells using an ultramicrotome for photoactive layer cutting is proposed and applied. The method creates an opportunity to take advantage of atomic-force microscopy in structural investigations of the bulk of soft samples. Such advantages of atomic-force microscopy include a high contrast and the ability to measure various surface properties at nanometer resolution. Using the proposed method, samples of the photoactive layer of polymer solar cells based on a mixture of PTB7 polythiophene and PC71BM fullerene derivatives are studied. The disclosed details of the bulk structure of this mixture allow us to draw additional conclusions about the effect of morphology on the efficiency of organic solar cells.
