From the project

This repository contains the designs for the Big Red Sat-1, a 1U CubeSat examining the performance of perovskite solar cells in low earth orbit.

This repository contains the original designs for the Big Red Sat-1 1U CubeSat, conceived, designed, and launched by a multi-disciplinary team of middle schoolers and high schoolers from the Nebraska public school system, as well as undergraduate students and graduate students from the University of Nebraska-Lincoln.

The goal of this scientific mission is to characterize the performance and degradation of experimental perovskite solar cells from the National Renewable Energy Laboratory while in low earth orbit. To accomplish this, a custom precision curve tracer was designed along with a…
