Free-Standing TiO2 Nanotube Arrays for Front-Side Illuminated CdS Quantum Dots Sensitized Solar Cells

Near infrared light‐induced photocurrent in NaYF4:Yb3+, Er3+/WO2.72 composite film

“…Solar cells without the pollutions and consumption of fossil fuels present an effective and promising strategy to obtain the renewable and clear energy . The core components of solar cells are the semiconductors such as silicon, organic, and inorganic perovskite . The semiconductors can absorb the sunlight with energy close to their band gap energy, exciting the electrons located at the valence band to the conduction band.…”

“…[1][2][3] The core components of solar cells are the semiconductors such as silicon, organic, and inorganic perovskite. [4][5][6] The semiconductors can absorb the sunlight with energy close to their band gap energy, exciting the electrons located at the valence band to the conduction band. Thus, the electrons and holes were generated in the semiconductors, and the electron or holes transfer result in the production of photocurrent in the solar cells.…”
