The main purpose of this work was to study the effect of electric currents reverse stress on the capacitance and in general the performance of photovoltaic modules. Different levels of reverse stress current are injected into the solar cell structure and the C-V characteristic are measured in the dark and illuminated conditions, at room temperature for several common periods of time. A digital double exponential model was used to analyze the experimental measurements. The dramatic changes in capacitance characteristics are caused from the effect of a reverse current introduced for different stress levels, simulated the effect of accumulated extreme reverse currents that can occur in the solar cells and modules for different reasons. The paper contributes to research on the adverse effects of reverse currents on the capacitance and normal functioning of cells and solar modules.

“…These factors intricately interact with one another. Thus, a deep understanding of FF is difficult to achieve [21], and from these factors, voltage drops because of shunt resistance R sh , series resistance R s and the recombination in a nonideal solar cell [22]. Table 2 shows that the FF and conversion efficiency increase with V appl.…”

Alignment nanofibers of poly(o-toluidine)/polystyrene (POT/PS) were prepared by using an electrospinning method at different applied voltages (V appl.) of 10, 15, and 20 kV. The effect of the applied voltage on the morphology and electrical properties of POT/PS nanofibers was studied. Morphology and diameters of the nanofibers were investigated via atomic force microscopy. (POT/PS)/Si hybrid solar cells were fabricated through the deposition of POT/PS nanofibers on Si wafers using the electrospinning technique. The current-voltage measurements of the device under dark conditions exhibited asymmetrical and rectifying behavior for the Al/(POT/PS)/Si/Al junction, thereby confirming the formation of diodes. Diode parameters, such as ideality factor n* and saturation current I o , were determined from the current density-voltage curves. The photovoltaic properties of the Al/(POT/PS)/Si/Al junction were studied under illuminated condition. Results revealed short-circuit current density J sc = 1.45 mA, open-circuit voltage V oc = 596 mV, and solar cell efficiency = 3.04.

“…Conventional multicrystalline silicon solar cells typically have three reverse bias breakdown mechanisms, known as early breakdown (−4V to À9V), soft breakdown (−9V to À13V), and hard breakdown (beyond À13V) [13,14]. Conventional monocrystalline silicon solar cells exhibit a relatively linear relationship between the reverse current and voltage at low reverse bias voltages [15]. The most important mechanism for junction breakdown in monocrystalline silicon solar cells is avalanche breakdown [16,17].…”

Residential photovoltaic systems often experience partial shading from chimneys, trees or other structures, which can induce hot-spots in the modules. If the temperature and frequency of these hot-spots are high, the module's reliability and safety may be at risk. IEC 61215-2:2021 hot-spot endurance test is utilized to evaluate the materials' ability to withstand partial shading. Since modules in residential systems can be subjected to higher temperatures than those in the open field, IEC TS 63126:2020 recommends adjusting the module temperature for the hot-spot endurance test according to the module's operating temperature. This study tested the hot-spot endurance of PERC, IBC and HJT modules under standard (55 °C) and more severe (75 °C, Level 2 condition in IEC TS 63126:2020) test conditions, as well as outdoor accelerated-ageing tests were performed with shadow masks. The results demonstrated that irrespective of environmental conditions, hot-spots can form at lower temperatures, with more shading-tolerant cells (i.e., cells with lower breakdown voltage) or with shorter strings. We also show that it is possible to shorten the effort- and time-consuming hot-spot endurance test described in the standard and obtain similar results. In addition, the hot-spot endurance test for residential PV systems was evaluated in terms of module temperatures and duration. In this respect, we propose to increase the testing temperatures of the hot-spot endurance testing for modules operating at high temperatures in IEC TS 63126:2020.
