[Analysis Case] Evaluation of Composition Distribution in the Active Layer of Organic Thin-Film Solar Cells
Preprocessing and depth direction analysis are possible under controlled atmosphere conditions.
In bulk heterojunction solar cells using p-type and n-type material active layers, it is necessary to properly control the mixing state of the materials within the film. After performing annealing treatment post-deposition, we conducted TOF-SIMS depth profiling analysis on samples that showed an improvement in photoelectric conversion efficiency along with an increase in fill factor without any change in open-circuit voltage. As a result, it was found that PCBM was segregated at the interface with the PEDOT:PSS layer before annealing.
