| 與硅太陽能電池和染料敏化太陽能電池相比,量子點太陽能電池成本低、性能優(yōu)越、具有更廣闊的前景,而采用固態(tài)電解質(zhì)制備全固態(tài)量子點太陽能電池的研究更是太陽能電池的未來發(fā)展方向。如何改進光電極的電子傳輸和固體電解質(zhì)的填充是提高電池性能的關(guān)鍵所在。本項目通過兩步陽極氧化法制備出TiO2納米管陣列作為電子的超快傳輸通道,首先采用連續(xù)離子層吸附與反應(yīng)法在TiO2納米管陣列表面沉積CdS核層量子點,通過離子置換法構(gòu)建核殼結(jié)構(gòu)量子點作敏化劑,然后通過電化學(xué)法在納米管中原位聚合PEDOT作為空穴的傳輸通道,制備出全固態(tài)核殼量子點敏化TiO2納米管陣列太陽能電池,并研究核殼量子點和PEDOT的制備條件對太陽能電池光吸收特性、電荷遷移特性以及光電轉(zhuǎn)換效率的影響,揭示TiO2納米管陣列/核殼量子點/PEDOT之間的電荷轉(zhuǎn)移與輸運機制。本項目的研究成果對于新型太陽能電池微觀結(jié)構(gòu)的設(shè)計和研究具有重要的科學(xué)意義。 |

| Compared with the silicon solar cell and dye-sensitized solar cell, quantum dots solar cell is characterized by its low cost, superior performance and ever broader prospects. It was demonstrated that future development direction of quantum dots solar cell is research all solid-state quantum dots solar cell based on solid electrolyte. Among related Technologies, key technologie include how to improve the electron transport in photoelectrode and how to fill suitable electrolyte. This project application will carry on a study in two-step anodization TiO2 nanotube arrays as ultrafast electron transport channels: the first, A CdS nuclear layer is deposited on surface of TiO2 nanotube arrays by successive ionic layer adsorption and reaction (SILAR), shell structure of quantum dots as a sensitizer was built through ion replacement method; the second, electrochemical method is used to form a hole transport channel in the nanotube via situ polymerization of PEDOT, we get the all solid state nuclear shell quantum dots sensitized TiO2 nanotube array solar cells. On this basis, we will perform a further exploration of the relationship between the nuclear shell quantum dots and PEDOT preparation condition on both optical absorption properties and photoelectric conversion efficiency of the new solar cell. Our work would help for revealing the mechanism of mechanism of charge transfer and transport between TiO2 nanotube arrays / core-shell quantum dots / PEDOT. The research project has important scientific significance for the design and study of a new solar cell microstructure. |

| Compared with the silicon solar cells and the dye sensitized solar cells, the quantum dot (QD) solar cells have the advantages of lower cost, better performance and wider applications, and one trend is to develop the all-solid-state QD solar cells with solid electrolytes. The key to the performance of solar cells lies in how to improve the electron transport of the photoelectrode and the filling of solid electrolytes. In this research, the two-step anodic oxidation method was utilized to prepare the TiO2 nanoarray as the ultrafast transmission channel for electrons, and CdS QDs were deposited on the nanoarrays by successive ionic layer adsorption and reaction process, followed by the formation of the core-shell QDs as the sensitizer with the ion replacement method. Then PEDOT, which acts as the transmission channel for holes, was prepared in the nanotubes by in-situ polymerization via the electrochemical process. The all-solid-state QD-sensitized TiO2 nanoarray solar cells were thus fabricated. Effects of the fabrication conditions for the core-shell QDs and PEDOTs were studied on the absorption properties, charge transfer and photoelectric conversion efficiency of the solar cells, and the mechanism for charge transfer and transport were revealed in the TiO2 nanoarrays/core-shell QDs/PEDOTs. This finding is of great scientific significance to the microstructure design and study of novel solar cells. |
