The Influence of MoS2 Thickness on the Efficiency of Solar Energy Conversion in TiO2/MoS2/P3HT Cells
In the era of global energy crisis, more attention is paid to efficient energy harvesting from renewable sources. Solar power is one of those widely utilized, yet the efficiency of devices converting energy needs to be constantly improved. One of the ideas is to create solar cells that benefit from 2D van der Waals structures combined with other materials such as TiO2 and conductive polymers. Such hybrid solar cells show higher power conversion compared to non-composite photovoltaic devices. In this work, a TiO2/MoS2 heterojunction created in the magnetron sputtering process was covered with a P3HT polymer coating. Composite multilayer systems were investigated (TEM, XRD, Raman spectroscopy and TOF-SIMS) to define the composition, optical properties and solar energy conversion potential. The photovoltaic response of the multilayer system was successfully improved by MoS2 band gap engineering based on the quantum size effect. Furthermore, TiO2/MoS2/P3HT revealed enhanced optical properties and improved charge transport performance with reasonable energy band alignment. The photovoltaic efficiency of hybrid cells doubled compared to previously published work and reached 2.7%. Furthermore, the photovoltaic performance of the solar cells based on TiO2/MoS2/P3HT exhibited an improvement compared to that of the solar cell based on TiO2/P3HT or MoS2/P3HT.
期刊介绍：
Progress in Photovoltaics offers a prestigious forum for reporting advances in this rapidly developing technology, aiming to reach all interested professionals, researchers and energy policy-makers.
The key criterion is that all papers submitted should report substantial “progress” in photovoltaics.
Papers are encouraged that report substantial “progress” such as gains in independently certified solar cell efficiency, eligible for a new entry in the journal''s widely referenced Solar Cell Efficiency Tables.
Examples of papers that will not be considered for publication are those that report development in materials without relation to data on cell performance, routine analysis, characterisation or modelling of cells or processing sequences, routine reports of system performance, improvements in electronic hardware design, or country programs, although invited papers may occasionally be solicited in these areas to capture accumulated “progress”.
