Photovoltaic Cell Defect Severity Classification with Squeeze-and-Excitation Enhanced ResNet50 on the ELPV Benchmark Dataset

Öz

Cell defects in photovoltaic (PV) modules directly affect production yield, making early and reliable detection critical. Electroluminescence (EL) imaging is widely used for this purpose since it reveals defects such as microcracks and inactive regions; however, manual assessment is time-consuming and subjective. In this study, EL images from the public ELPV benchmark dataset are automatically classified into four defect-severity levels (flawless, low, medium, high). The proposed method augments a ResNet50 backbone with the Squeeze-and-Excitation (SE) block, which adaptively recalibrates channel-wise features. The model is compared against ResNet50, MobileNetV2 and EfficientNetB0 baselines using ImageNet pretrained weights and stratified 5-fold cross-validation. The proposed SE-ResNet50 outperforms all baselines with 0.7609 accuracy and 0.559 macro-F1. Furthermore, an ordinal error-magnitude analysis shows that the SE block yields the smallest and closest errors, reducing the mean absolute level error to 0.443. Nevertheless, the contribution of SE remains limited for the minority 'medium' class, indicating that class imbalance is the principal bottleneck.
