Measuring Temperature with a Silicon Diode
ثبت نشده
چکیده
Due to the high sensitivity, nearly linear response, and easy availability, we will use a 1N4148 diode for the temperature transducer in our measurements. The current conducted through an ideal diode is described by the Shockley ideal diode equation: I D = I S exp q V D n k B T − 1 where q is the electron charge, k B is Boltzmann's constant, T is the temperature of the diode junction, and V D is the voltage across the diode (positive voltage indicates a forward-biased diode). n is a quality factor or emission coefficient that typically lies in the range of 1–2 and is usually assumed to be approximately 2 for a diode.

متن کاملAnalysis of Temperature Effect on a Crystalline Silicon Photovoltaic Module Performance
In this paper, the effect of the cell-temperature on the performance of photovoltaic (PV) module is evaluated. The evaluation is based on a mathematical module (single diode equivalent circuit) and practically based on solar module tester (SMT). Solara®130W PV crystalline silicon module was used in this simulation. The SMT is able to supply a constant irradiance level (1000W/m2) or any other de...
