Sažetak
Recently, organic photovoltaics have received increased attention due to combination of their comparatively simple and cost effective processing and ability to derive low weight, flexible thin-film solar cells. The process of electron-hole pair generation and its extraction toward the electrodes is essential to achieve high performance for all photovoltaic devices and can be influenced by a number of common approaches, such as increasing open circuit voltage by tuning the bandgap of the photoactive material as well as optimization of the deposition geometry i.e. tailoring the optimal film morphology through molecular interactions to improve charge carrier transport and extract maximum current. The latest is of particular interest for small photoactive organic molecules, such as squaraine dyes and their derivatives, as they show great preference in supramolecular assembly based on molecular design when deposited into thinfilms. Squaraine photoactive donors used in solar cells are generally mixed with acceptor materials, such as fullerene or their derivatives into bulk heterojunction layers to widen the absorption spectra and induce efficient charge separation and transfer. In this study, an optimal synthesis route and film deposition parameters were determined by mixing of several squaraines with a number of commercial acceptors in various ratios and subsequent depositions. The samples were characterized through SEM and AFM to examine film morphology and ToF-SIMS to study vertical phase distribution of the donor/acceptor system. Absorption spectra reveals that the degree of aggregation influences optical properties of squaraine substantially. Finally, a comparison of inverted and conventional configurations is displayed to highlight the importance of the direction of current for self-assembling bulk heterojunction layers .
