“…Additionally, the hybrid transparent solar module exhibited a series resistance of 2.3 Ω cm 2 (Figure 1g), similar to the series resistance of a commercial c‐Si solar module (2–4 Ω cm 2 ). [ 22,23 ] Furthermore, the FF of the fabricated transparent c‐Si solar module was 74.45%, which was 159% higher than that of the solar module interconnected using only microgrid electrodes with micrometer‐scale interconnection electrodes (Figure 1h and Table 1 ). These results show that the new modularization method effectively reduces carrier collection loss.…”

Transparent solar cells can be used where conventional solar cells are inapplicable, such as, in glass windows of buildings; however, reports on modularization, which is essential for their commercialization, are scarce. Here, a novel modularization method has been proposed for the fabrication of transparent solar cells and a 100‐cm2 neutral‐color transparent crystalline‐silicon solar module has been developed using a hybrid electrode comprising a microgrid electrode and an edge busbar electrode. The transparent solar module exhibits a power conversion efficiency (PCE) of 11.94 and 13.14% when connected in series and in parallel, respectively, with an average visible transmittance of 20%. Additionally, the module exhibits negligible losses in PCE (lower than 0.23%) in outdoor, mechanical‐load, and damp‐heat (at 85°C/85% RH) stability tests, indicating high stability. The transparent solar module proposes here could facilitate the commercialization of transparent solar cells.

“…One of the most critical aspects influencing PV module performance is series resistance. Some researchers are discovered that the series resistance is affected on the FF and power output of PV modules due to the series resistance has a greater impact on the solar cell's output power than any other parameter [3,5,6]. Also, the 𝑅 𝑠 is reduced the short-circuit current but it didn't influence on the 𝑉 𝑜𝑐 [7].…”

In this paper, a theoretical investigation to the effect of the series resistance ( ) on the solar cell output parameters, such as efficiency (η), open-circuit voltage ( ) , output maximum power ( ) , fill factor (FF) and short circuit current( ) was performed. Multisim software was used to achieve the investigation. It is reproduced by using the current-voltage (I-V) characteristics in accordance with double-diode modeling of the solar cell. The results showed that there is a change in the characteristic curve form due to the variation of series resistance values between (0.01- 0.5) Ohm. Moreover, it was found that the fill factor, short circuit current, and open circuit voltage decreased linearly when the value of the series resistance increased. Consequently, the conversion efficiency of the solar cell declined. In other words, the series resistance has a significant effect on the performance of the solar cell.

Aiming at improving the effectiveness and real-time performance of the fault detection of the photovoltaic (PV) array under different outdoor conditions, a novel method based on Grubbs criterion and local outlier factor (G-LOF) method is proposed in this study. The simulation model of the PV array is built to obtain the reference current of each PV string. The local outlier factor (LOF) is a ratio of the average local reachability density of sample neighbourhoods relative to its local reachability density. In this study, the LOF is used to quantify the abnormality by comparing the measured current and the simulated reference current. To reduce the false alarm probability of LOF, the Grubbs criterion is utilised as the test criterion to detect the abnormality of PV strings and it is merged with the LOF to derivate the G-LOF. The experiments of partial shading, open-circuit fault and short-circuit fault of PV modules are implemented in sunny and cloudy days. Experimental results verify that the proposed G-LOF method can sensitively detect above abnormalities, especially can detect the slight performance reduction caused by the partial shading or faults.
