9. Since this difference is equal to the voltage of a properly designed solar cell, luminescence is the key indicator of material quality for solar cells. 对于太阳能电池,因为费米能级差等于电池的伏特数,所以发光性能是电池材料质量的一个重要指标。
(1) Generally the cell voltage U(I) means the electrical potential difference or terminal voltage between the two electrodes of an electrochemical cell at any temperature, when current is flowing through the cell. In the case of a three-electrode cell, the cell voltage equals the potential diff...
The ratio of a sinusoidal voltage, applied across two terminals of a measurement cell, to the sinusoidal component of the current flowing between the terminals that results from the applied potential difference. From: Encyclopedia of Physical Science and Technology (Third Edition), 2003 ...

(R1) must ensure that its voltage drop due to reference and load currents equals the difference between supply voltage and reference voltage. R1 must be calculated at minimum supply voltage and maximum load current to ensure operation under this worst-case condition. The following equations ...
High-performance e-compressors for EV thermal management Designed to enhance the driving experience, Infineon's high-voltage e-compressor as the heart of the heat pump system ensures a comfortable journey during hot summers and chilly winters. By reusing thermal energy from the drivetrain, the e-...
The current-voltage curve (CVC) is most convenient when it is necessary to know the potential difference across the entire membrane system without dividing it into components, such as across the bipolar region, monolayers, solution diffusion layers, etc. ...
Thus, the difference in forward voltage is directly proportional to temperature. If the two current levels are forced with good accuracy, temperature can be calculated from a measured ΔVBE almost without regard to the initial forward voltage, physical size of the junction, leakage, or other junc...
