Crystallinities
WebApr 10, 2024 · It is inferred that the activation of solar cells with ethanol and Acetonitrile solvents have reduced the crystallinities, microstructures and morphologies of D149-sensitized ZnO layer, leading to a reduction in photons harvesting by solar cells and thus lower performance. However, the results have revealed that the improvement in … WebPET/PBT samples crystallization behavior of the polymers were studied at a range of cooling rates using a Diamond DSC. Thanks to the power compensation design which supports accurate heat flow rate measurement, heats of transition, heat capacities, temperature-dependent crystallinities etc. can be established at the extreme rates applied.
