  本篇英国代写论文-钙钛矿太阳能电池讲了标准的钙钛矿太阳能电池是一个非倒置的钙钛矿太阳能电池是建立在玻璃/ITO形式的衬底。衬底位于金属背面,为了使钙钛矿成为一个工作模型,必须有用于接口的区域。由此产生了两个界面层,分别是电子层和空穴层。通常在标准界面层的情况下没有太多的问题被报道,这可能是因为用于该层的聚合物的种类比其他的工作得更好。本篇英国代写论文文章由英国第一论文 Assignment First辅导网整理,供大家参考阅读。

  Literature Review

  The standard Perovskite solar cell is the non-inverted one that the Perovskite solar cell is built on glass/ITO form of substrates. The substrate rests on a metal back and in order to make the Perovskite a working model it is necessary to have the regions for the interfacing. Two interface layers are hence created which are for the electrons and the holes. Usually there are not much issues reported in the case of the standard interface layer and this could be because the class of polymers that are used for the layers work much better than others (Park, 2015). For instance, studies show that PEDOT:PSS and the PTAA-class of polymers are seen to make better hole interface layers in the perovskite solar cell. On the other hand, the material that is used to construct the electron interface is different. The electron interface is constructed by means of PCBM, C60, ZnO and TiO2.

  Once again in deciding for the material to develop and use as hole interact or electron interface is not exactly a fixed thing, this is because research on the topic is still under development and hence it cannot really be said with clarity on what the comprehensive list of materials is in this context. Research needs to be conducted in order to study how energy levels might be maximized or might be minimized when different materials are being made use of. Some of the interface can be studied by means of permutation and combinations.
