The concept of fuzzy Galois connections is defined on fuzzy posets with Bělohlávek's fuzzy Galois connections as a special case. The properties of fuzzy Galois connections are investigated. Then the relations between fuzzy Galois connections and fuzzy closure operators, fuzzy interior operators are studied.

We evaluate an efficient semiconductor-sensitized solar cell (SSC) based on the poly(3-hexylthiophene) (P3HT)@CdSe@ZnO core−shell nanorod arrays as a photoanode. A simple and low cost electrodeposition method was applied on the whole preparation process. It has been demonstrated that coating vertical CdSe@ZnO core−shell nanorod arrays with P3HT to form p−n heterojunctions largely improves the photovoltaic performance of the CdSe@ZnO core−shell nanorod SSCs, exhibiting an energy conversion efficiency of 0.88%.
