Colloidal quantum dot solar cells (CQDSCs) are attracting growing attention owing to significant improvements in efficiency. However, even the best depleted-heterojunction CQDSCs currently display open-circuit voltages (VOCs) at least 0.5 V below the voltage corresponding to the bandgap. We find that the tail of states in the conduction band of the metal oxide layer can limit the achievable dev...
The quantum efficiency of the organic solar cell with a small driving force can be increased by using second donor chemical structure similar to primary donor, while low voltage loss is very well maintained.
Improving the Energetic Efficiency of Biogas Plants Using Enzymatic Additives to Anaerobic Digestion
This study was carried out to estimate the relevance of biological supplementation in improving economic efficiency anaerobic digestion (AD). Three kinds silages—maize, grass, and igniscum—were initially inoculated with digestate then supplemented one four vaccines containing different bacteria species (APD®, PPT®, JENOR®) or a yeast mold mixture (HAP®). In addition, each plant silage fermented...
Abstract Background Hypertrophic Cardiomyopathy (HCM) is mainly caused by sarcomeric mutations. In about 40% of cases the causal mutation unknown. Myocardial mechano-energetic efficiency per unit left ventricular (LV) mass (MEEi) an echocardiographic parameter LV pump performance. Sarcomeric mutations may affect energy efficiency. Purpose We investigated effects presence on MEEi in patients wit...
