In order to accurately evaluate the materials, structures and manufacture of DSSC, an exact measurement method on DSSCs’ photovoltaic character is necessary.
It was reported the traditional monochromatic incident photon-to-electron conversion efficiency (IPCE) measurement method in previous studies, such as the American Society for Testing and Materials standard (ASTM), is not suitable for measuring the IPCE of dye-sensitized solar cells (DSSCs) [3].

The THF process depends on reasonable selection of material, right performing and reasonable loading paths, etc.
Then the tube is locked in the axial direction for reducing material flow over the corner.
Guo Cheng et al. [9] developed a device to evaluate the material formability in THF.
