Electron beam induced current method and crystal orientation analysis using SEM.
CIGS thin-film polycrystalline solar cells are expected to be low-cost next-generation solar cells. Development is underway for large-area and high-quality production. To evaluate the characteristics of the polycrystalline thin film, we conducted assessments of the pn junction using EBIC and crystal grain evaluation using EBSD on the same cross-section. We prepared a cross-section of the CIGS film and measured the open-circuit voltage (EBIC) by scanning an electron beam, visualizing the in-plane distribution of the open-circuit voltage. Additionally, by measuring EBSD on the same surface, we correlated the distribution of the open-circuit voltage with the crystal grains.
