Overview

PVCracks is the DuraMAT project that investigates the effects of cracks on power loss in photovoltaic (PV) solar cells and tracks crack progression over time. We provide:

  • Open-source cell-level imaging and electrical datasets
  • MultiSolSegment: segmentation of cracks, busbars, and dark areas in electroluminescence (EL) images
  • Variational Autoencoder (VAE): parameterization & clustering of segmented data
  • XGBoost model: estimation of power loss (ΔPMPP) per cell
  • pvspice_lite: spice toolset for simulating current-voltage (I-V) curves and building synthetic module I-Vs (more features to come)
