Since their use in the discovery of dark energy, Type Ia Supernovae (SNe Ia) have remained one of our most powerful tools to constrain the expansion history of our universe. Modern cosmological measurements using SNe Ia have largely relied on spectroscopy to both confirm the type of SN and obtain reliable redshifts. While this has been feasible for our current datasets (~2k SNe), our spectroscopic resources will be vastly outpaced by the troves of SNe (O(100k)) soon to be discovered by imminent surveys such as the Vera Rubin Observatory Legacy Survey of Space and Time (LSST). Without efforts to address the limitations imposed by requiring spectroscopy, the power of these surveys to constrain dark energy and its time evolution will be drastically diminished. In this talk, I will highlight work using data from the Dark Energy Survey (DES) that shows photometric SNIa cosmology using photometric redshifts rather than spectroscopic redshifts is a promising avenue for next-generation constraints.
