In this paper, the effect of using semi-transparent Carbon
nanotube layer (CNT) on the efficiency of perovskite
solar cell (PSC) is investigated. One of the most
important process in PCS is charge collecting. In this
regard, Carbon nanotubes have the ability to act as charge
collector layer in solar cell. Carbon nanotubes, due to
suitable optical and electrical properties such as
transparency, high mobility and stability have been
widely used in solar cell structures. In the proposed
structure, we use semi-transparent CNT layer as charge
collector on top of PSC. This layer with low resistance
path for transport charge carriers has increased short
circuit current and other performance parameters of solar
cell. The proposed device structure
ITO/CNT/TiO2/CH3NH3PbI3/Spiro-OMeTAD is
simulated with Silvaco TCAD. The simulation results
show that the efficiency of the perovskite solar cell with
semi-transparent CNT layer is reached 23.59% which is
3.15% higher than simple perovskite solar cell structure
under AM1.5G. تفاصيل المقالة
