6 FAQs about [Fitting curve of silicon solar cell]
What is the absorption coefficient of silicon solar cells?
For silicon solar cells it is desirable to know the absorption coefficient over the range of 1.1–4.0 eV and over a wide range of temperature, particularly when evaluating the concentration type systems. An analytical (empirical) expression has been developed for this purpose.
Can c-Si solar cells be corrected with a dark IV -curve?
Lipps suggested a method to use the dark IV -curves for correction. Using a combination of forward and backward sweep, Winter et al. investigated the possibility of averaging the currents, concluding that the approach is not feasible for c-Si solar cells due to the asymmetric nature of the error.
How to increase the throughput of solar cell production lines?
To satisfy the increasing demand for solar cells, the throughput of solar cell production lines increases continuously. To further increase the throughput, the voltage sweep duration during IV -characterization is desired to be as short as possible.
Why is a solar cell production line important?
It allows the extraction of central performance indicators such as efficiency η, fill factor FF, maximum power Pmax, short-circuit current Isc and open-circuit voltage Voc. To satisfy the increasing demand for solar cells, the throughput of solar cell production lines increases continuously.
What is the lattice vibration spectrum of silicon?
The lattice vibration spectrum of silicon has been studied in detail by Brockhouse using neutron spectroscopy [12, 13]. Four branches of the lattice waves, LA, LO, TA and TO have been characterized in the (100) direction, the direction in which the minimum of the conduction band of silicon lies.
