Interface electronic device for reading an output signal and for controlling and conditioning a three-electrodes amperometric sensor
No full textElectronic devices and methods for reading an output signal and controlling a three-electrode electro-chemical amperometric sensor include an operational amplifier having a non-inverting input adapted to receive a biasing electric potential and an inverting input connectable to a reference electrode of the sensor. The devices further include one or more MOS transistors connected to the operational amplifier, with a first MOS transistor connectable to the collector electrode of the sensor to receive or supply a MOS transistor channel current representative of the cell current generated in the sensor, and a second MOS transistor connectable to a reference voltage by a conductor or a resistor. The resistance is lower than the cell impedance such that the current in the second MOS transistor channel depends on the current in the first MOS transistor channel through a nonlinear gain dependent on the resisto
Tackling Performance Challenges in Organic Photovoltaics: An Overview about Compatibilizers
Full text linkOrganic Photovoltaics (OPVs) based on Bulk Heterojunction (BHJ) blends are a mature technology. Having started their intensive development two decades ago, their low cost, processability and flexibility rapidly funneled the interest of the scientific community, searching for new solutions to expand solar photovoltaics market and promote sustainable development. However, their robust implementation is hampered by some issues, concerning the choice of the donor/acceptor materials, the device thermal/photo-stability, and, last but not least, their morphology. Indeed, the morphological profile of BHJs has a strong impact over charge generation, collection, and recombination processes; control over nano/microstructural morphology would be desirable, aiming at finely tuning the device performance and overcoming those previously mentioned critical issues. The employ of compatibilizers has emerged as a promising, economically sustainable, and widely applicable approach for the donor/acceptor interface (D/A-I) optimization. Thus, improvements in the global performance of the devices can be achieved without making use of more complex architectures. Even though several materials have been deeply documented and reported as effective compatibilizing agents, scientific reports are quite fragmentary. Here we would like to offer a panoramic overview of the literature on compatibilizers, focusing on the progression documented in the last decade
