1. Introduction. Solar cell or photovoltaic (PV) module is technically characterized by current–voltage measurement (IV characteristic) either under illumination (according to IEC60904-1) or in the dark.The parameters measured typically consist of series resistance, parallel resistance, a combination of the shunt resistance and diode resistance.
We consider two extrem cases for both variants, series and parallel connection of N – 1 identical good cells and one bad one: The bad cell has a very large series resistance and no noticeable shunt resistance; The bad cell has a regular

While the panels'' solar cells are robust, their connecting joints represent a critical point of potential failure, necessitating thorough analysis. Despite extensive research into the reliability of space-bound systems, studies analyzing the combined effects of temperature changes and AO are scarce. This study employs parallel gap resistance welding (PGRW) to
Tandem solar cells are the best approach to maximize the light harvesting and adjust the overall absorption of the cell to the solar irradiance spectrum. Usually, the front and back subcells are connected in series in two-terminal device (2T) designs which require a current matching between both subcells in order to avoid potential losses
We consider two extrem cases for both variants, series and parallel connection of N – 1 identical good cells and one bad one: The bad cell has a very large series resistance and no noticeable shunt resistance; The bad cell has a regular series resistance and a very small shunt resistance. Let''s see what will happen in the parallel world.
In addition to series resistance, solar cells also have parallel resistance, which is caused by the imperfect P-N junction or impurities near the junction, resulting in short circuit or
Applying antisolvent in perovskite improves carrier mobility, transport properties, and higher power conversion efficiency (PCE) achieved. This study focuses on the effects of series (R s) and shunt resistance (R s h) of f-PSCs on photovoltaic parameters while controlling the surface morphology of perovskite films applied on both structures.
) and parallel resistance current (I sh). However, the equivalent circuit can be used not only for a PV module including several cells, but also for an individual cell or a PV array including several PV modules [2]. The most important parameters of solar cells can be determined by the I–V characteristic which is shown in figure 1(b).

The loss mechanism of the shunt path increases the leakage current which is higher than that of the ideal diode. This effect affects the J-V characteristics of the solar cells [, , , , , , ]. So, if the shunt resistance is reduced, the PSCs will be much more stable and get better efficiency at lower illumination.
We will now: Discuss in more detail, whilst using the corresponding equations, the functioning of a solar cell; the goal here is to look at the main parameters of the solar cell: short-circuit current density Jsc, open-circuit voltage Voc, Fill Factor FF and efficiency η.
Series resistance (R s) mainly depends on the front and back surface contact resistance of f-PSCs [, , , ]. When increases R s then the carrier density decreases as a result current decreases in the cells.
Typical characteristics of solar cells: dark characteristics and illuminated characteristics. The “active quadrant” is the quadrant, where the solar cell can furnish power to a load; MPP is the “maximum power point”, the point on the illuminated characteristics, where the power furnished to the load is a maximum (see text).
To evaluate the efficiency of a solar cell/module, we have to consider both the spectral response curve SR (λ) of the solar cell, as well as the spectrum of the incoming light (see Chap. 2). 1.
