A close-up of a polycrystalline photovoltaic (PV) cell, showing blue tint and a patchwork of crystal domains. First, let’s look at the efficiencies of other familiar uses of energy to put PV into perspective. Snark Attack So 15% is far too low for you? Perhaps you drive a car. Electric cars deliver battery-stored energy to the wheels at something like 85% efficiency. If you’re low on energy, you might consider eating. Perhaps you are a fan of biofuels.
