N2 - A double-heterostructure copper phthalocyanine/C 60 organic photovoltaic cells with series resistance were demonstrated. A high fill factor of ∼0.6 was achieved, which was only slightly reduced at very high intense illumination. It was found that the power conversion efficiency increases with the incident optical power density.
Mismatch losses are experienced by series-connected PV cells due to non-identical characteristics. If any single module is shaded, it draws a lower amount of current than the other modules.

The I PV PV current increases in proportion to the incident irradiance. If the spectrum does not change, the I PV is directly proportional to irradiance I PV = C G G.Then, at a constant temperature, the V OC increases with irradiance logarithmically, as follows from Eq.

The total power of solar panels connected in series is the summation of the maximum power of the individual panels connected in series. However, because every panel in a series connection is important in the circuit, this type of connection might not be ideal in applications where there is a possibility of shade covering some of the panels.
In the series connection the voltages of all solar panels are summed up and the current is maintained the same for all the panels. The set of solar panels connected in series is known as a string. As stated before: lower voltages imply higher currents and higher voltages imply lower currents.
So suppose each of these solar panels has a rated voltage of 24 V and amperage of 4 A. In such a scenario, the total voltage of the series connection would be 96 V, while the amperage would remain at 4 A. Solar panels connected in series are ideal in applications with low-amperage and high voltage and power requirements.
