When we connect N-number of solar cells in series then we get two terminals and the voltage across these two terminals is the sum of the voltages of the cells connected in series. For example, if the of a single cell is 0.3 V and 10 such cells are connected in series than the total voltage across the string will be 0.3 V × 10 = 3 Volts.
The best real-world silicon solar cell to date, developed by Kaneka Corporation, is able to achieve 26.7% conversion efficiency 7, 8. A loss analysis of this 165 μm -thick, heterojunction IBC cell shows that in absence of any extrinsic loss mechanism the limiting efficiency of such a cell would be 29.1% 7.
Efficiency is the ratio of output power (pout) to input power (Pin) where the conversion efficiency is the output electric power divided by the result of solar irradiation (E) and the surface area (A) of the solar panel. Multiplying the measured output voltage and current equal to the output power , . ...
According to this modern version of the SQ limit, the maximum theoretical efficiency of solar cells made of crystalline (amorphous) Si is η ∼ 33 % (∼28 %) that, nowadays, corresponds to the most accepted value.
It is from 1954 the first estimate of the maximum efficiency (around 22 %) a Si solar cell can exhibit, and it was made by the same scientists that invented the device (Chapin et al., 1954).
Determine heating in the solar cell due to light absorption. The heat generation profile is obtained from the optical simulation by calculating the energy from absorbed photons with energy above the bandgap of the semiconductor material. The HEAT solver calculates the steadystate temperature profile within the solar cell.

Bulk and surface recombination decrease the short circuit current by ~10% as can be extracted from the y-crossing of the plots. The open circuit voltage for the solar cell can also be extracted from the x-crossing of the plot. The script file can also generate power curves of the solar cell which are necessary for efficiency calculation.
