This will never happen, simply because the total amount of solar energy falling onto a car’s roof is a very small fraction of the energy needed for average daily driving. The expense is largely bound up in the two-hours-per-cell metalorganic vapor phase epitaxy (MOVPE) production process, which involves several chemical vapors being deposited onto a substrate in a single chamber. Earth and Space Science 573. Kelsey Horowitz, part of the techno economic analysis group at the NREL’s Strategic Energy Analysis Center, suggested D-HVPE cells made at scale could generate electricity at $0.20-0.80/W, with the help of some tweaks and said applications such as electric vehicle integration, systems for roofs not strong enough to support a silicon PV array, and portable or wearable solar panels could be viable at that cost.
