染料敏化太阳能电池

太阳能的有效利用是解决化石能源的日益枯竭及温室效应和环境污染等问题的重要途径之一。太阳能电池能实现无机械转化和污染副产品的情况下，把太阳能直接转化为电能，一直是研究热点。染料敏化太阳能电池由于其价格便宜、工艺简单、环境友好、形状多样化等优点而可能替代传统的硅基电池。染料敏化太阳能电池通常由在导电基底上的敏化纳晶多孔半导体作为工作电极，由铂等作为对电极，在两片电极中间由含有氧化还原电对的电解质构成。氧化还原电对在两片电极之间传输电子，同时在电子注入到半导体能带后使激发态染料得以再生。近年，腐蚀性低，吸光弱的基于联吡啶钴的电解质使得电解质的发展逐渐转向无碘电解质。我们已经成功将过渡金属(钴、锰等)配合物氧化还原电对用于染料敏化太阳能电池中并取得了优异的光电转换效率。通过对电解质进行凝胶固化，器件的稳定性得到了很大的提升。同时，我们采用水作为电解质溶剂来代替有毒的有机溶剂，获得了目前世界效率最高的水电解质染料敏化太阳能电池，这是制备环境友好的太阳能电池器件的一个重要途径。研究成果分别发表在能源与化学顶级期刊Energy & Environ. Sci.，Angew. Chem. In. Ed.，ChemSusChem等并被选为封面文章和热点文章进行报道。

钙钛矿太阳能电池

有机无机杂化钙钛矿太阳能电池自2012年起已在世界范围内进行广泛的研究，并被科学杂志选为2013年科学界十大突破之一。在这种新型全固态杂化太阳能电池中，具有ABX3晶型结构的有机-无机-卤素钙钛矿材料为吸光材料。A是有机阳离子，B是金属离子，X是卤素离子。这种三卤钙钛矿材料具有很宽的吸光范围(300-800 nm)和高摩尔吸光系数，因此，很薄的一层吸光层(~ 300 nm)就足以满足高效钙钛矿太阳能电池的要求。而提高钙钛矿太阳能电池光电转换效率和稳定性的方法在于材料的选择和工艺的优化。这种低成本和简单工艺的太阳能电池是光伏建筑一体化工程的重要组成部分。

五、Research field (no more than 3)

Due to the gradual depletion of fossil fuels and the increasing energy demand to support the current model of economic growth,mankind is facing a global energy problem. Amongst the number of alternative resources, renewable energies are rapidly becoming the leading solution to fulfill the growing needs of power sources. At present, solar energy is considered the most promising renewable resource. A simple calculation leads self-evidently to the conclusion that covering only around 0.1% of the earth’s surface by means of energy conversion devices having an efficiency of about 10% would satisfy the present global energy needs. These encouraging numbers are inducing the scientific community to make even greater efforts towards the direction of improving solar energy conversion technologies as well as proposing new intriguing solutions.

Dye-sensitized solar cells

Dye-sensitized solar cells (DSCs) have been intensely studied as promising renewable energy technology with the potential to achieve high energy conversion efficiencies at low cost. DSCs typically consist of a sensitized mesoporous semiconductor film on a conductive substrate as working electrode and a platinized counter electrode, bridged by an electrolyte film containing the reduced and oxidized forms of the redox mediator. The latter mediates charge transport between the two electrodes and is also responsible for the regeneration of the photooxidized dye, following electron injection into the TiO2. The application of a cobalt(II)/(III) tris(bipyridine) based electrolyte has recently resulted in a benchmark efficiency of >12%. This result has accelerated the transition to non-iodide based electrolytes, which are less corrosive and exhibit weaker absorption of visible light. Transition metal, such as cobalt, iron and manganese based redox couple have been successfully developed and promising efficiencies were obtained in both n-type and p-type DSCs. By solidifying the electrolyte, the stability of the devices can be further improved. More mportantly, the replacement of organic solvent in the electrolyte with water paves the way for environmentally friendly devices, which keeps us in the leading role in this area worldwide. These breakthroughs were published on Energy & Environ.Sci. and Angew. Chem. In. Ed., and one of them was selected as the front-cover and hot article.

Perovskite solar cells

Alkylammonium lead(II) halides ([CH3NH3PbX3]n) have been shown to be efficient photovoltaic materials with excellent light harvesting, high carrier mobility, and facile solution processability. A rapid growth of intensive research into this photovoltaic technology since 2012 has resulted in a certified energy conversion efficiency over 20% and the topic has been selected as one of the top 10 breakthroughs of 2013 as announced by the journal Science.These organic– inorganic lead(II) complexes crystallize in the well-known perovskite structure with general formula ABX3, where A is an organic cation, Bis a metal, and X is a halide. A very thin perovskite film (~ 300 nm) is sufficient enough for highly-performed perovskite solar cell due to its broad light absorption range from 300 to 800 nm and a high molar extinction coefficient. Materials selection and process optimization are essential to high performance of perovskite solar cells with long-term stability. This new type of solar cells with low cost and easy fabrication is the key part of the building integrated photovoltaics (BIPV).
