Evaluation of the Aging Process of Dye-Sensitized Solar Cells Under Different Stress Conditions

Recovery of Photovoltaic Potential-Induced Degradation Utilizing Automatic Indirect Voltage Source

“…As we understand from former research that PID severely impacts the performance of PV modules [1,7], we had experienced the same outcomes after employing the PID test on the PV string. Accordingly, we have taken the EL images before the PID test (Figure 3(a)).…”

“…Although PV modules have long been considered reliable under field conditions with low degradation and failure rates, they can be affected by diverse degradation mechanisms, which collectively reduce the module crop power over time. One of the main degradation mechanisms is called potential-inducted-degradation (PID) [1][2][3]. For many PV systems, PID is one of the leading causes of module degradation caused by the high voltage between the encapsulants and the front glass surface, which is grounded via the substructure of the cell or the frame [4].…”

“…PID becomes more prevailing as the module ages, and whilst it normally doesn't affect all the solar cells in the module, it does have a critical impact as it cannot be repaired [5]. For example, in recent studies [1,6], PV modules with different types of structure (poly/monocrystalline silicon) were subjected to PID experiments under the IEC61215 standard [7]. They explain that there are 8-30% power losses under standard test conditions.…”

Metrology and Measurement Systems

“…In general, manufacturers do not provide information on model parameters, although they constitute the base for the characterisation of a photovoltaic panel. Moreover, the long exposure of a panel causes it to suffer multiple forms of degradation [9,10], which also unpredictably changes the values of the model parameters [11][12][13]. Therefore, identifying the photovoltaic model parameters from the current-voltage measurements is crucial to the characterization of PV panels.…”

Assembly Considerations for Dye-Sensitized Solar Modules with Polymer Gel Electrolyte

“…Because stability is one of the main features for commercialization of DSSCs, all the components of the device have to be carefully selected, looking at the compatibility among them, the power generated and shelf life. Several reports discuss stability tests for DSSCs carried out in outdoor conditions ,− or with application of temperature, − and excellent reviews about DSSCs stability can be found elsewhere. , Overall, it is accepted that high-quality sealing is required to prevent physical degradation (i.e., electrolyte evaporation or leakage); effective isolation of metal grids from the electrolyte is necessary, and changes in the composition of the electrolyte, either via physical process (iodine sublimation, crystallization, etc.) or via unwanted chemical reactions, , might happen and have to be considered.…”
