A solar furnace is a device that uses concentrated solar power to produce high temperatures for industrial processes or research, while solar cells (or photovoltaic cells) are devices that convert sunlight directly into electricity. Solar furnaces are used for heat generation, while solar cells are used for electricity generation.
Provided you are nowhere near the focal point of the furnace then they are perfectly safe.
