16. Conjugated materials for organic electronic devices : photoelectron spectroscopy studies
Sammanfattning : Conjugated materials have attracted great attention since the discovery of high conductivity in donor and acceptor doped polyacetylene over two decades ago. The discoveries mentioned below caused, however, that the interest begun to shift towards their pristine semi-conducting state. LÄS MER
17. Novel organic sensitizers and hole transport materials for efficient solid-state photovoltaic devices
Sammanfattning : State-of-art solid-state photovoltaic devices, such as solid-state dye sensitized solar cells (ssDSSCs) and perovskite solar cells have attracted significant attention due to their high efficiency and potential low-cost manufacture. However, there are still challenges that limit the application up-scaling.. LÄS MER
