What I’m not seeing here is when this will be put into manufacturing and what off the manufacturing line tandem cells output production will look like. The other boggle is the recent Biden rise in the 201,301 tariff rates on many goods and materials being shipped from China, how will that affect getting this product manufactured by JinkoSolar into the Florida factory sooner than later? What about international certification of these new tandem cells? What about passing IEC 61xxx certifications is this being done now? I’m thinking U.S. company First Solar is also doing R&D testing and analysis on tandem solar PV cells and panels. It has been previously announced that Sunpower and First Solar have been working on a silicon-perovskite tandem that has been projected at the end of this year or the beginning of next year. This would be the kind of thing that will push the solar cell solar harvest efficiency out to around 35%. IF First Solar gets this product ironed out by 2025 and the promised manufacturing for the “residential market” a current best efficiency panel of around 24% would provide for at least the first year of use around 9kWp for 400 square feet of roof space and around 13.5kWp for a 600 square foot array. With the tandem silicon-perovskite at the projected at least first year of 35% efficiency, it would make a 400 square foot array about 13kWp and 600 square feet 19.6kWp a substantial bump in efficiency. Now the overarching concern is will this tandem be able to compete directly with curent TOPCon silicon cell based panels or will the LeTID become a problem to be able to compete with single silicon of 24% that is said to have 2% cell degradation the first year and some panels are claiming 0.5% to 0.25% degradation every year after? Basically a 30 year panel warranty for current silicon crystal solar PV panels is around 83.5% to 91% power output after (30) years of daily use.
