Abstract
A photovoltaic apparatus includes a substrate, a light-concentrating heat sink unit and a solar cell. The light-concentrating heat sink unit includes a carrier connected to the substrate, at least two fins extending from the carrier, and at least two reflective layers each extending on a related one of the fins. The solar cell includes a lower electrode and a solder layer of low thermal resistance provided between the lower electrode and the carrier.
