A good question. Light can not exactly move an object into space but once an object is in space the light from the sun can be used to move it, and I don't mean solar panels harnessing electricity. A probe can actually have a "sail" like panel protruting from it that can harness radiation being given off by the sun and use it like a sail boat does to harness energy for movement. You might have heard the term solar wind which is basically the same idea. Believe it or not, space probes and other vehicals can obtain pretty fast speeds just by using solar wind. Hope this information was helpful.
