高效率鈣鈦礦太陽能電池

通過開發(fā)新型溶液法制備基于有機無機混合型鈣鈦礦CH3NH3PbI3材料的高效率的廉價太陽能電池，該項技術(shù)由于實現(xiàn)了低成本和高效率的兩大目標,并且可以在不同襯底上制備各種顏色的高效電池，使其成為很有商業(yè)應用前景的熱點研究。我們通過設計新的合成體系實現(xiàn)了了動力學調(diào)控合成具有特殊納米結(jié)構(gòu)的鈣鈦礦材料，實現(xiàn)了電池的高效率和高穩(wěn)定性。

High Efficiency Low Cost Perovskite Solar Cell

Most recently, lead halide perovskites CH3NH3PbI3, developed by Park, Gratzel, Snaith, Seok and other pioneering groups, have been emerged as one of the most promising materials for low-cost solar cells with >15% efficiency.This new cells are made from a low cost inorganic/organic hybrid perovskite CH3NH3PbX3 with tunable spectrum to efficiently absorb sunlight. The material is easy to fabricate using solution chemistry, which could be printed on substrates like ink in a printing press, or made from simple evaporation. We had developed a MACl assistant kinetic control growth of high quality CH3NH3PbX3 as an easy, affordable route to fabricate high efficiency solar cells.

光電化學光解水電池Photoelectrochemical Water Splitting Cells

利用原料廣泛可以充分利用可見光的硅材料制備空氣中穩(wěn)定的納米硅光電極，將其用于高效率的光催化產(chǎn)氫。開發(fā)和制備納米結(jié)構(gòu)的高性能的穩(wěn)定性產(chǎn)氧反應助催化劑，設計和研究取代貴金屬的低成本催化劑用于光電化學電池的產(chǎn)氧反應。通過組合光陽極和光陰極來實現(xiàn)高效率的完全光解水。

Photoelectrochemical Water Splitting Cells

Photosynthesis is a proof of a very large scale solar fuel demonstrated by nature. Although photosynthesis provides all the food and the fossil fuel, the energy conversion efficiency in photosynthesis is just about 1%, which is much lower than photovoltaics. Photoelectrochemical cells (PECs) is a promising technique to achieve higher solar fuel conversion efficiency. Our research focus on developing air stable nanostructured photocathod based on inexpensive, earth-abundant, and industrially mature Si with the advantages of a low band gap that uses much of the solar spectrum and more active surface area for hydrogen production.We also work on  developing high active catalysts to overcome kinetically demanding process in the four-electron oxidation of water limit the performance of photoanodes to achieve a better overall water splitting PECs.

用于環(huán)境催化的多孔功能材料

    多孔功能材料由于其較高的比表面積，規(guī)則的孔道結(jié)構(gòu)，易修飾的表面性質(zhì)以及組分可調(diào)而提供了優(yōu)異的吸附、催化的微納米空間，，也逐漸用于環(huán)境中不同形態(tài)污染物的治理。新興多孔功能材料的開發(fā)以及在環(huán)境催化中的應用是未來污染控制材料的重要選擇和環(huán)境污染物治理的重要手段。

Porous functional materials for Environment catalysis

Owing to the high surface area, ordered porous structures, easily functionalized surface properties and various compositions, porous functional materials provides excellent adsorption and catalysis micro/nano-space, which have been widely used in remediation of all kinds of environmental pollutants. We are focusing on developing new porous functional materials and their practical applications in environmental catalysis as the candidates for pollution control and environmental pollution remediation, respectively.

環(huán)境凈化光催化材料

    光催化屬于高級氧化中的一類新興氧化技術(shù)，其基本原理是通過光激發(fā)半導體材料后形成的電子和空穴，以及電子和空穴與周圍物種間形成的自由基，進而利用電子的還原能力以及氧化物中和空穴的氧化能力凈化環(huán)境污染物。到目前為止，光催化存在量子效率低，太陽光中可見-紅外光部分利用不足，光催化劑失活等問題。我們致力于開發(fā)高效、低廉以及高壽命的光催化材料，實現(xiàn)對太陽能最大效率利用等問題。

Photocatalysis for environmental remediation

    Photocatalysis belongs to one of the most popular oxidation techniques in the advanced oxidation process (AOP). The basic principle of photocatalysis is to cleanup environmental pollutants via the redox reaction by photoexicted electrons/holes or their derived radicals under the irritation of sunlight. We are dedicated to develope efficient, low-cost and long use-life photocatalytic materials and realizing the maxium utilization of solar energy.
