摘要:
The present invention discloses a solar cell having a multi-layered structure that is used to generate, transport, and collect electric charges. The multi-layered nanostructure comprises a cathode, a conducting metal layer, a photo-active layer, a hole-transport layer, and an anode. The photo-active layer comprises a tree-like nanostructure array and a conjugate polymer filler. The tree-like nanostructure array is used as an electron acceptor while the conjugate polymer filler is as an electron donor. The tree-like nanostructure array comprises a trunk part and a branch part. The trunk part is formed in-situ on the surface of the conducting metal layer and is used to provide a long straight transport pathway to transport electrons. The large contact area between the branch part and the conjugate polymer filler provides electron-hole separation.

A photovoltachromic device includes a photoelectrode, a counter electrode electrically connected to the photoelectrode, and an electrolyte layer disposed between the photoelectrode and the counter electrode. The photoelectrode includes a first transparent electrode, an electron-transport layer disposed on the first transparent electrode, and a sensitizing layer disposed on the electron-transport layer. The counter electrode includes a second transparent electrode and an electrochromic layer disposed on the second transparent electrode. The second transparent electrode contacts both of the electrolyte layer and the electrochromic layer thereby accelerating the response times for coloring and bleaching the photovoltachromic device.
摘要:
A lithium aluminum oxide (LiAlO2) substrate suitable for a zinc oxide (ZnO) buffer layer is found. The ZnO buffer layer is grown on the LiAlO2 substrate. Because the LiAlO2 substrate has a similar structure to that of the ZnO buffer layer, a quantum confined stark effect (QCSE) is effectively eliminated. And a photoelectrical device made with the present invention, like a light emitting diode, a piezoelectric material or a laser diode, thus obtains an enhanced light emitting efficiency.
