Abstract:In view of the environment characteristics of the Moon, Mars, Jupiter exploration missions, this paper points out key technology of Mars spectrum simulation method, Mars spectrum solar cell design, the Mars dust removal technical route for Mars surface landing and patrolling missions and low intensity low temperature (LILT) solar cell I-V curve anomaly risks for Jupiter orbiting missions. Based the engineering experience, we provide the power output calculation method of solar panel for Mars surface and Jupiter orbiting exploration in the absence of particular condition solar simulator. This paper has been significant for engineers in the field of deep space exploration.
