dc.description.abstract | The conjugated small donor molecule p-DTS(FBTTh2)(2), leading to efficient bulk heterojunction organic photovoltaic devices with PC71BM, shows a eutectic phase behavior in combination with its homocoupled analogue. Rapid heat-cool differential scanning calorimetry allows us to construct the state diagram based on (i) the endset of melting of p-DTS(FBTTh2)(2):homocoupled p-DTS(FBTTh2)(2) mixtures of different compositions, and (ii) partial integration of the melting trajectory of these mixtures by calculating the fraction of the molten pure excess phase as a function of temperature. These quantitative experimental results are supported by a theoretical calculation model based on Schroder-van Laar equations extended with an interaction function representing the interactions between the mixture's components in the liquid state. The eutectic composition around 30 wt % of homocoupled p-DTS(FBTTh2)(2) shows the lowest crystallinity (order) of all mixtures together with a maximum loss of photovoltaic efficiency. | - |
