Informal summary:
We studied the photovoltaic properties of the SunPower corporation's C60 monocrystalline, back contact solar cells to determine if they could work as precise, large area photometric calibrators. Our results were promising, and limited only by the precision of our electronics. Conducting a series of experiments, we conclude that these solar cells are reliable photometric calibrators to 1% precision. Pushing to the sub-percent level, as we hope to do with LSST calibration, would require better electronic instruments.
We developed a statistical test, based on Fourier analysis, to search for evidence of such oscillations. We found that there was no evidence of cosmic oscillations, and constrained a few simple oscillatory cosmic models.
