Abstract:

The dye-sensitized solar cell(DSSC) has attracted a great attention in the solar energy conversion fields owing to its advantages including low cost, simple fabrication process, and relatively high efficiency. The component and microstructure of semiconductor photoanode as an important part of DSSC have direct roles on the photoelectrochemical performance of solar cell. Hollow micro/nano-structure can provide large surface area and high loading capacity of dyes, improve the light harvesting and promote the charge transport in photovoltaic devices. Therefore, the photoanode materials with hollow micro/nano-structures became a hot topic in recent years. This review addresses the progress of hollow micro/nano-structured photoanode materials, including hollow microsphere, hollow box,core-shell structure, hierarchical hollow microspheres, multi-shelled structure besides the pure or hybrid components. The relationships between each structure and power conversion efficiency(PCE) are analyzed especially. The facing challenge and prospect of hollow micro/nano-structured photoanode in the future are also discussed.

Key words: hollow micro/nano-structure, multi-shelled structure, dye-sensitized solar cells(DSSC), photoanode, power conversion efficiency(PCE)
