Abstract
The space solar cell considers the main source of energy for spacecraft
operation. The solar cell always threatened by space radiation where the
radiation can penetrate its structure and degrade its performance. This
performance will affect dramatically on the satellite mission’s lifetime.
Prediction the space solar cell performance is very important for satellite
design. This Prediction could be estimated by exposing the solar cell to
different fluences of radiation. High power Pulsed laser beam utilized
successfully to simulate the effects of space radiation on spacecraft electronic
components. This study investigates the impact of pulsed laser irradiation on
the Si solar cell. In this work, mono-crystalline silicon solar cells were exposed
to pulsed laser beam with two different wavelengths (1064nm, 532nm) at
different locations on the solar cell, in order to know the best damaging
exposure conditions. The electrical characterization of the solar cell is
determined before and after laser irradiation by electronic circuit. PC1D
software is used for physical characterization analysis to elaborate the
degradation of solar cell performance. Finally, the variation of electrical and
physical performance is determined as a function of pulsed laser fluence.
