What are some recent advancements and developments in solar energy use?

I’m doing a science report on solar energy, but I’m having a hard time finding information on more recent advances and developments in the area of harnessing solar power or putting it to use.
Also, how do solar chargers for cell phones, etc, work? Do they usually hook directly up to a solar panel, or do they connect a solar panel to a small solar cell, or…?

one simple device i’ve seen is a solar collector designed to heat water for residences. one variety consists of a piping or tubing laid out in a spiral shape or a rectangular panel, facing south to harness the sun’s rays to heat the water. it’s the same principle, as the ’sun shower’ used by outdoors enthusiasts.

some examples…
