Evaluation of electrical characteristics and crystalline in perovskite solar cells
Lead halide perovskite solar cells can be easily fabricated by solution coating and drying. Samples were prepared with different heat treatment times at the same one of 150 ℃ under nitrogen atmosphere. Here we evaluated the surface spreading resistance of the perovskite layer by SSRM measurements, the particle size or the phase fraction of perovskite (PVK) and PbI2 phases, and crystal orientation by ACOM-TEM analysis.

Surface analysis of power generation layer for Perovskite Solar Cells
Since the Perovskite Solar Cell (PSC) has high efficiency and simple manufacturing process, it is expected as the next generation solar cell. X-ray diffraction (XRD), SEM (Secondary Electron Microscopy), and SSRM (Scanning Spread Resistance Microscopy) can evaluate the crystal structure, the form of the surface, the distribution of element, and spread resistance.

Evolved gas analysis by TPD-MS and depth profile analysis by SIMS of perovskite solar cells
Lead halide perovskite solar cells can be deposited using the coating process, and inexpensive and highly efficient solar cells have become available. To improve the heat treatment process, it is important to understand the decomposed gases from the material and the composition distribution in the material. Here, we show the evaluation results of evolved gases during heating by TPD-MS and the elemental distribution in the depth direction by GCIB-TOF-SIMS and Dynamic-SIMS.

Depth profile analysis to element and organic matter of Perovskite Solar Cell
Since the Perovskite Solar Cell (PSC) has high efficiency and simple manufacturing process, it is expected as the next generation solar cell. Cross-sectional TEM, Dynamic-SIMS(D-SIMS) and GCIB-TOF-SIMS can be performed the distribution of element and organic matter with high spatial resolution and high sensitivity under non-exposed atmospheres.

Composition and impurity analysis of light absorbers of perovskite-based solar cells
It is important to figure out the concentration of composition and impurity of light absorbers to achieve high efficiency in perovskite-based solar cells. For the analysis of inorganic elements, ICP-AES, ICP-MS and ion chromatography are available.
