Kesterite solar cells offer a promising alternative to conventional solar cells but suffer from short-carrier lifetimes. This work introduces a comprehensive analytical model applicable to such solar cells. We developed a novel approach to accurately represent the recombination rates of the carriers within the depletion region using a Gaussian function. This model overcomes the limitations of existing approximations and enables more precise dark current calculations. Additionally, we employed a fully analytical generation rate calculation based on the transfer matrix method for accurate photocurrent determination. The effectiveness of this model was validated by comparing its results with simulated and experimental data for kesterite solar cells, demonstrating excellent agreement in dark current and photocurrent, with maximum percentage errors of 1.9% and 1.7%, respectively. Beyond accuracy, the model also achieved a 75-fold improvement in computation speed compared to finite element method simulations. This highlights the effectiveness of the model in capturing the complex recombination processes within kesterite solar cells and in providing a valuable tool for understanding and optimizing the performance of solar cells based on short-lifetime materials, particularly kesterite-based devices with one-sided junction characteristics.</p>\u0000 </div>","PeriodicalId":223,"journal":{"name":"Progress in Photovoltaics","volume":"33 8","pages":"890-904"},"PeriodicalIF":8.0,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144646953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the inherent instantaneous fluctuation nature of field test conditions, obtaining high quality repeatability measurement results of photovoltaic (PV) modules in the field is still challenging. In this paper, firstly, we defined repeatability of PV modules measurement in the field, including repeatability and relative repeatability of measured and standard test conditions (STC)-corrected electrical parameters for fielded PV modules. Because STC is quite difficult to directly obtain outdoors, the correction procedure 4 in IEC 60891:2021 is used to obtain module STC characteristics. Then, the effect of the correction procedure on repeatability of electrical parameters of PV modules in the field was studied. The results show that repeatability of electrical parameters is changed before and after correction process. The variation reason was revealed by the established repeatability error propagation model. It is remarkable that there exist module maximum power point offsets before and after module characteristics correction. Moreover, the covariance terms contribute significantly to repeatability variation for fielded PV modules. Finally, the effect of field test conditions variation on repeatability of electrical parameters of PV modules was studied. The relative repeatability precision of module STC maximum power between field and indoor measurements was also compared. It is found that there is a greater probability to obtain indoor-level repeatability results within 0.7–1.0 kW/m<sup>2</sup> irradiance ranges (3.29%–5.04%) than that within 0.3–0.7 kW/m<sup>2</sup> irradiance ranges (0.47%–2.90%) for PV measurements in the field.

However, evaluating these losses in different locations is complex, time-consuming, and expensive. To address this challenge, our study collected dust samples from various sites and conducted soiling experiments in the laboratory using standardized methods. The investigation correlated the transmittance loss (<i>T</i><sub><i>loss</i></sub>), short-circuit current loss (<i>Isc</i><sub><i>loss</i></sub>), and dust density with the surface coverage. As a result of this analysis, a direct and precise comparison of the individual soiling losses is possible based on the gradient of the correlation lines. Additional characterization of the dust enables an exact allocation of the soiling losses to the chemical composition, optical properties, water content, and particle size. Our study used dust samples from Morocco, Qatar, and two from Thailand. The data analysis indicates that three dusts exhibit a comparable slope in soiling loss relative to surface coverage. However, one dust from Thailand has a significantly higher slope of 12.8% in transmittance loss. A comparative evaluation of the <i>Isc</i><sub><i>loss</i></sub> reveals an identical ranking. A root cause analysis identified the differences in the soiling behavior through detailed dust characterization. In addition, the calculated <i>Isc</i><sub><i>loss</i></sub> based on the transmission measurements showed a discrepancy between measured and calculated <i>Isc</i><sub><i>loss</i></sub>. The deviation is quantified, and possible causes are described. The newly evaluated evidence of the different correlation slopes between the measurement methods not only contributes significantly to our understanding of the effects of dust on photovoltaic systems but also has practical implications.

Key issues include light-induced halide segregation in mixed halide high bandgap perovskites and the risk of solvent damage to underlying layers during top-cell deposition. To overcome these challenges, we developed a high bandgap, inorganic perovskite absorber, CsPbI<sub>2</sub>Br, using thermal evaporation at room temperature, eliminating the need for post-deposition annealing.
