The Brabender Plastograph EC drive units are the economical table-top version of the universal
Plasti-Corder Lab-Station models for applications with lower demands as to torque and speed levels. Both models are equipped with a 3.8 kW drive motor, which provides 200 Nm torque and maximum 150 min-1 speed. The Plastograph EC Plus design has an increased number of heat control and pressure read channels so that it can handle the conical twin screw and the 19 mm single screw extruders. The compatibility of the different
processing modules and Plastograph EC drive units can be seen in the schematic on the left.
Quantum efficiency (QE) and Incident Photon to Charge Carrier Efficiency (IPCE) indicates the ratio of the number of photons incident on a solar cell to the number of generated charge carriers. Specifically, QE is a measure of the external efficiency, while IPCE is a measure of the internal efficiency; that is, the photons reflected back from the surface of the cell are not considered. Both QE and IPCE measurements are of critical importance during the materials research and cell design stages. This is because the spectral response of the solar cell should be matched to the spectral distribution of sunlight to ensure highest efficiency in charge carrier generation.
