While SiOnyx, a MA-based startup, uses lasers to create black silicon and improve the efficiency and price of solar cells, researchers at the National Renewable Energy Laboratory (NREL) discovered a simple chemical treatment that could replace the otherwise expensive antireflective solar cell coatings currently used in the industry.

Concentrated photovoltaic systems are usually more effective than regular, flat ones, because a lens focuses the sunlight on a smaller surface of some efficient and more expensive solar cells 500 times stronger than the cells would receive in regular operation. Heat is mostly a problem with concentrated PV systems, since it has to be efficiently dissipated through complex and expensive cooling technique.
