Dr Ismael and the team published a paper on large-area CVD-grown monolayer MoS2-based flexible photovoltaic devices on ultrathin 3 μm polyimide films for space structures. A subnanometer-thick single MoS2 monolayer absorber characterized under 1 sun AM0 illumination achieved a VOC of 0.180 V and a specific power of 0.001 kW/kg. Model projections also indicate a 12.97 kW/kg specific power can be obtained for a 100 nm-thick MoS2 (stacked monolayers) absorber layer. Techno-economic analysis shows that, despite the lower efficiency of 2D TMDC-based PV arrays designed for a 6U CubeSat, their specific power is 2 orders of magnitude higher than a Si PERC panel, and the cost when deployed in space forecasts to be 1 order of magnitude less. This signifies that this flexible, large-area, high-specific power 2D material-based PV has excellent potential for space applications. Read all about it here.
