Power conversion efficiency enhancement of polymer solar cells using MoO3/TFB as hole transport layer

Halide based perovskite offers numerous advantages such as high-efficiency, low-cost, and simple fabrication for flexible solar cells. However, long-term stability as well as environmentally green lead-free applications are the real challenges for their commercialization. Generally, the best reported perovskite solar cells are composed of toxic lead (Pb) and unstable polymer as the absorber and electron/hole-transport layer, respectively. Therefore, in this study, we proposed and simulated the photovoltaic responses of lead-free absorber such as cesium titanium (IV) bromide, Cs2TiBr6 with dopant free electron phenyl-C61-butyric acid methyl ester (PCBM), and dopant free hole transport layer N,N′-Di(1-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine (NPB) for the Ag/BCP/PCBM/Cs2TiBr6/NPB/ITO based perovskite solar cell. After comprehensive optimization of each layer through vigorous simulations with the help of software SCAPS 1D, it is observed that the proposed solar cell can yield maximum power-conversion efficiency up to 16.85%. This efficiency is slightly better than the previously reported power-conversion efficiency of a similar type of perovskite solar cell. We believe that the outcome of this study will not only improve our knowledge, but also triggers further investigation for the dopant and lead-free perovskite solar cell.

Widespread Application

Abstract State-of-art perovskite solar cells exhibit comparable power conversion efficiency to silicon photovoltaics. However, the device stability remains a major obstacle that restricts widespread application. Doping hole transport layer induced hygroscopicity, ion diffusion, and use of polar solvent are detrimental factors for performance degradation of perovskite solar cells. Here, we report phase transfer catalyzed LiTFSI doping in Spiro-OMeTAD to address these negative impacts. 12-crown-4 as an efficient phase transfer catalyst promotes the dissolution of LiTFSI without requiring acetonitrile. Crowning Li+ ions by forming more stable and less diffusive crown ether-Li+ complexes retards the generation of hygroscopic lithium oxides and mitigates Li+ ion migration. Optimized solar cells deliver enhanced power conversion efficiency and significantly improved stability under humid and thermal conditions compared with the control device. This method can also be applied to dope π-conjugated polymer. Our findings provide a facile avenue to improve the long-term stability of perovskite solar cells.

Niobium Doped

Organometal halide perovskite materials have shown high potential as light absorbers for photovoltaic applications. In this work, perovskite planar solar cells were fabricated on corning substrates with the structure as follows: the first layer made of tantalum-doped tin oxide as transparent contact material, followed by sputtering niobium-doped titanium oxide as the compact electron transport layer; covered with perovskite CH3NH3PbI3 as the light harvester by combination between spin-coating and dipping methods; CuSCN was evaporated as the hole transport layer; the final thin Al/Ag electrodes were deposited. This configuration is shortly described as Al/TTO/NTO/CH3NH3PbI3/CuSCN/Ag. Such heterojunctions are expected to be suitable for the development of efficient hybrid solar cells. The fabricated cells were measured under the air mass 1.5 illumination condition, showed the rectification effect and exhibited a power conversion efficiency of 0.007%, with a open circuit voltage of 53.2 mV, a short circuit current of 0.36 mA/cm2, and a form factor of 37%. The power conversion efficiency will be further optimized in near future.
