On the influence of temperature on crystalline silicon solar cell
The reverse saturation current, I 0, is a measure of the leakage or recombination of minority carriers across the p–n junction in reverse bias. The reverse saturation current is therefore the pre-dominant factor affecting the open circuit voltage, V oc. As minority carriers are thermally generated, I 0 is highly sensitive to temperature.

7 Choice of photodiode materials A photodiode material should be chosen with a bandgap energy slightly less than the photon energy corresponding to the longest operating wavelength of the system. This gives a sufficiently high absorption coefficient to ensure a good response, and yet limits the number of thermally generated carriers in order to attain a low "dark current" (i.e.

What is the ideality factor of silicon solar cells?
The ideality factor (m) in the equivalent circuit of silicon solar cells is consistently ranging from 1 to 2 and rarely falls below 1, resulting in a relatively lower FF than 85%. Here, this work complements a systematic simulation study to demonstrate how to approach the FF limit in design of silicon solar cells.
What are the parameters of a mono-crystalline silicon solar cell?
Khan et al applied the variation of slopes of the I-V curves of a cell at short circuit and open circuit conditions to determine the parameters of the cell, namely the series resistance Rs, shunt resistance Rsh, the ideality factor, n, and the saturation current, Is, the of a cell of mono-crystalline silicon solar cell.
Where are the data points of high-performance silicon solar cells located?
The data points of different high-performance silicon solar cell are located between the two blue dashed lines marked by RS = 0.2 Ω·cm 2 and RS = 0.4 Ω·cm 2, indicating they obeys the trend of “intrinsic recombination + surface recombination” curve but with RS of 0.2–0.4 Ω·cm 2. Realization of ultra-high FF in c-Si solar cell.
How does irradiance affect the performance of a solar cell?
When solar cells are utilized for indoor applications or integrated into a building, they are generally exposed to variable irradiance intensity. The performance of a solar cell is influenced by this variation as its performance parameters, viz. open-circuit voltage (Voc), short-circuit current (Isc), fill factor (FF) and efficiency (η).
What is Ke in a polycrystalline silicon solar cell?

What is VOC in a silicon solar cell?
For the ideal silicon solar cell, the quasi-Fermi level across all regions in bulk is assumed as same, and thus, the implied VOC (i VOC, i.e., the difference between the two quasi-Fermi level for electrons and holes) equals to the applied voltage (more details are showed in Figure S1).
