Solar Impulse 2, a fully electric plane, has landed in California after its team spent months fixing a problem with overheated batteries:
An experimental plane flying around the world without a single drop of fuel landed in California after a two-and-a-half day flight across the Pacific. Piloted by Swiss explorer and psychiatrist Bertrand Piccard, Solar Impulse 2 touched down in Mountain View just before midnight (3 a.m. ET). "It's a new era. It's not science fiction. It's today," Piccard told CNN from California after his successful voyage. "It exists and clean technologies can do the impossible."
While Borschberg set a new record for the solo flight, clocking in at 117 hours and 52 minutes, a chain of events caused the batteries to overheat. It was only after he landed that the team discovered how bad the damage was. "We made a mistake with our batteries," Piccard said after the plane touched down in July. "It was a human mistake." And a mistake that took more than nine months to fix. Fast forward to this spring, and the Solar Impulse 2 has new batteries, a new cooling system that can be manually operated by the pilot, and $20 million in fresh funding to keep the mission up and running.
[...] After several stops in the United States, the pilots hope to cross the Atlantic Ocean, and then Europe or northern Africa. They plan to return to the Middle East by late summer, completing a 35,000-kilometer (27,000-mile) trip around the world.

there are many people looking at alternative materials.
Silicon is just currently, cheap enough and plentiful enough.

This doesn't mean they are inherently not clean, as in "they cannot be manufactured in a clean way". The very source you linked states at the end of the article
Also, do you imagine that the photovoltaics the pane is using were produced in a back alley factory in China?
My googling shows [sunpower.com] that Solar Impulse is " using a special Maxeon™ solar cell design of remarkable lightness and efficiency."
