Jinko To Reuters: Our Jacksonville Factory Is Still On Track

Jinko Solar, being a public company, has to be as positive as possible. So when Reuters asked the Chinese module manufacturer whether the new round of tariffs imposed by the Trump Administration – 25% on modules and cells on top of the 30% the administration already imposed on all imported cells – my old friend Jeff Juger had a ready answer.

He told the news service that the Jacksonville factory, which was originally supposed to double as the company’s U.S. headquarters, will be producing modules by the fourth quarter based on cells manufactured in Malaysia, which may be true now. But sources close to the factory say the original plans involved cells manufactured in China. Trump’s tariffs sent those plans into a tailspin, however, despite China being the most cost-effective source for the cells.

Juger also told Reuters he hoped Trump’s administration would exempt the Malyasian cells from the tariffs under the exemption plan included in the original tariff pronouncement. He maintains the Jinko factory in Malaysia is the only factory that produces the necessary cells and discussed how much the success of the Jacksonville factory could turn on getting the exemption, telling the news service:

The 2.5 gigawatt exemption gives us quite a bit of headroom to import tariff-free cells. If the government grants that exclusion request and lets us import these cells, it will allow us to further scale up the factory in Florida.

Therein, of course, lies the rub. It’s worth noting that initially, the factory was going to be double the size than what it’s currently projected to be and was supposed to support twice as many jobs. If the company doesn’t get the exemption it’s seeking, it’s fair to ask when, if ever, the Jacksonville Jinko factory will be running at full capacity.

For Jacksonville’s sake, we hope Jinko gets the exemption. It would be shame if that much ballyhooed factory ends up being more of a whimper than a bang.

Could Perovskites Be Right Around the Corner? Solar-Tectic Earns Patents For Thin-Film Perovskite Technology

By Frank Andorka, Senior Correspondent

Perovskites have been the hot solar technology for several years now without, frankly, a lot to show for it. But one company – Solar-Tectic – has reached the patent stage for its thin-film perovskite technology.

Could perovskite modules be close behind? The answer is a definite maybe.

According to the company’s release, the breakthrough is the width of the bottom layer in the tandem cell. The release says:

Wafer sized bottom poly- and monocrystalline silicon layers in PERC, PERL, HIT, HJ, or perovskite/silicon tandem cells are typically 200-280 microns thick, whereas ST’s thin-film crystalline inorganic bottom layers can be as thin as 20-30 microns with the same or similar efficiency; moreover, they can be processed at much lower temperatures thereby lowering costs of production significantly.

Most solar observers believe perovskites would be a valuable addition to the solar space because their photovoltaic properties are much more sensitive than silicon, meaning their conversion efficiencies – how well they convert sunlight to electricity – is much higher. The theoretical conversion efficiency for perovskites is nearly 45%, almost twice the highest silicon cell efficiency (though in reality, thin-film modules such as First Solar’s have nearly reached a 30% efficiency).

The breakthrough patents correspond to a “Tandem Series” of solar cell technologies which has been launched by ST, and that includes a variety of different proven semiconductor photovoltaic materials (i.e. III-V, CZTS, a-Si, etc) for the top layer on silicon (or germanium) bottom layer, on various substrates such as cheap soda-lime glass. Last year, ST announced the first patent ever granted for this perovskite/silicon thin-film tandem approach.

Interestingly, the entire ST process is environmentally friendly since non-toxic Sn (tin) or Au (gold) is used to deposit the crystalline silicon thin-film material for the bottom layer in the tandem/heterojunction configuration as well as in the top, perovskite, layer.
