Graphene-functionalisation of solid-state dye sensitivity

光伏(PV)市场目前由晶硅太阳能电池(c-SiSC)主导，具有21%的功率转换效率(PCE)，但这种技术的广泛使用是成本有限的。或者，薄膜太阳能电池(TFSC)的制造成本很低，但性能不如c-SiSC，而且退化速度也比c-SiSC快。尽管TFSC技术的最新进展是使用钙钛矿吸收层，但光伏电池设计中的一个主要挑战是优化电荷收集，需要取得重大突破才能达到理论上的最大PCE。因此，有人提出，石墨烯前所未有的电子和结构性质为改变TFSC的效率和表面稳定性提供了一个独特的机会，通过精心设计的石墨烯将其引入TFSC。该项目旨在证明将石墨烯引入基于钙钛矿的薄膜固态染料敏化太阳能电池(SsDSC)中的概念，充分探索可能的效率提高以及石墨烯封装器件表面性能的改善。一个成功的项目的成果可以产生SC性能的阶梯变化，以比现有的c-Si SC技术更低的成本提供更高的PCE，并减少退化。

The photovoltaic (PV) market is currently dominated by crystalline silicon solar cells (c-SiSC), with < 21 % power conversion efficiency (PCE), but widespread use of this technologyis cost-limited. Alternatively, thin film solar cells (TFSC) can be manufactured cheaply but donot perform comparably and degrade more quickly than c-Si SC. Although recent advances inTFSC technology have been made using perovskite absorbing layers, a principle challenge inPV cell design is optimising charge collection and a significant breakthrough is required toachieve the theoretical maximum PCE. It has therefore been proposed that the unprecedentedelectronic and structural properties of graphene offer a unique opportunity for a step changeimprovement in TFSC efficiency and surface stability, through carefully engineeredincorporation of graphene into TFSC. The project aims to prove the concept of grapheneincorporation into thin film solid-state Dye Sensitised Solar Cells (ssDSC) based onperovskite, fully exploring the possible efficiency gains, as well as improvements to thesurface properties of graphene encapsulated devices. The outcomes of a successful project canbe developed to produce a step change in SC performance, providing higher PCE at lowercost than existing c-Si SC technologies, with reduced degradation.
