Using a liquid or gel electrolyte as a hole transfer medium, the DSSCs with 4.31 % or 2.75 % global photon-to-electron conversion efficiency was obtained, respectively.

The more we transfer from hole to hole, the happier we become.

Don't need to seal box, make transfer person can see after made, microwave oven, oven can cut a hole to let a person see the items in the versions.
