The proposed method is improved the classification performance and stability by integrating the residual connection and SPP into the inception network.
The statistical metric values indicate that the proposed Res-Inc-v3-SPP provides a more effective generalization capability in classifying PV solar cell defects. When all deep learning models are investigated in terms of their Pr and F1 values, the proposed method has the most impressive results, which are 93.94% and 93.64%, respectively.
