Solar cells
Summary
The project is about manufacturing procedures for solar cells. Based on the details given by the client and based on our study, we have conducted patent search and prepared the taxonomy
Taxonomy
The patent documents will be clustered based on following taxonomy. More nodes could be added during patent analysis.
