As one of the core components of PV modules, solar panel performance is strongly influenced by its temperature. Moreover, different types of SCs respond differently to temperature. And the
In the past, concentrator photovoltaics for space applications using multi-junctions solar cells (>1 cm 2) have struggled to balance high concentrating factors with large angular tolerances, while keeping a low-mass and compact optics; along with an advanced thermal cooling.
Solar cells (SCs) are the most ubiquitous and reliable energy generation systems for aerospace applications. Nowadays, III–V multijunction solar cells (MJSCs) represent the standard commercial technology for powering spacecraft, thanks to their high-power conversion efficiency and certified reliability/stability while operating in orbit.
A focus is made to study the feasibility of concentrator photovoltaics, which demonstrated record performances, reaching a cell efficiency of 47.1%. These systems do not seem to be adapted to missions with environments: highly scattered, with temperatures higher than 523 K and solar irradiances exceeding 3000 W/m 2.
Abstract — To successfully operate a photovoltaic (PV) array system in space requires planning and testing to account for the effects of the space environment.
For high-temperature operation, as discussed before, a high-bandgap solar cell ma-terial would be preferred, but the blue-deficient spectrum puts a limit on the availability of short-wavelength photons.
Currently, micro-concentrator photovoltaic systems using µ-cells (<900 µm 2) have the potential to address all these issues at once, reducing the optical profile and mass, and improving a passive thermal management, while having a moderate concentration factor (<100X).
