The cost of solar photovoltaic cells has dropped a stunning 90 percent over the past decade, partly because of ramped-up manufacturing—particularly in China—Bahar says.

When inventor Charles Fritts created the first crude solar photovoltaic cells in the 1880s, one might have thought the achievement would rapidly revolutionize global electricity production.

International Trade Commission recommended levying comparatively modest tariffs on imports of silicon-based solar photovoltaic cells and solar panels.

By 2030, utility-scale solar photovoltaic cells—big arrays of panels, not the rooftop version—will take the title of cheapest new power source.

China also produced 60% of the world's solar photovoltaic cells in 2014, yet less than 5% of these panels were installed domestically.
