6 FAQs about [Solar cell defect dataset]
Are defective solar cells affecting the power efficiency of solar modules?
The dataset contains 2,624 samples of 300x300 pixels 8-bit grayscale images of functional and defective solar cells with varying degree of degradations extracted from 44 different solar modules. The defects in the annotated images are either of intrinsic or extrinsic type and are known to reduce the power efficiency of solar modules.
Can deep learning detect defects in crystalline silicon solar cells?
This paper presents a benchmark dataset and results for automatic detection and classification using deep learning models trained on 24 defects and features in EL images of crystalline silicon solar cells. The dataset consists of 593 cell images with ground truth masks corresponding to the pixel-level labels for each feature and defect.
What is automatic defect detection & classification in solar cells?
Automatic defect detection and classification in solar cells is the subject of many publications since EL imaging of silicon solar cells was first introduced by Fuyuki et al. for detection of deteriorated areas in solar cells in 2005.
How are solar cell images annotated?
Every image is annotated with a defect probability (a floating point value between 0 and 1) and the type of the solar module (either mono- or polycrystalline) the solar cell image was originally extracted from. The individual images are stored in the images directory and the corresponding annotations in labels.csv.
Can El models detect defects in solar cells?
The models tested are effective in detecting, localizing, and quantifying multiple features and defects in EL images of solar cells. These models can thus be used to not only detect the presence of defects, but to track their evolution over time as modules are re-imaged throughout their lifetime.
What are the defects in El images?
The defects in the annotated images are either of intrinsic or extrinsic type and are known to reduce the power efficiency of solar modules. All images are normalized with respect to size and perspective. Additionally, any distortion induced by the camera lens used to capture the EL images was eliminated prior to solar cell extraction.
