The CEO of 1366 Innovations, Frank van Mierlo, is a betting man. And your humble narrator bets that high-efficiency solar tandem cells are the near-term commercial potential of solar technology.
The CEO of 1366 Innovations, Frank van Mierlo, is a betting man. And he is wagering that by the end of 2022, the solar market will see 2 GW of tandem solar on the market”.
In the other hand of this wager, I am the sceptic for one glass of fine champagne, while I would consider in its place a thimbleful of the CEO’s tears.
“I never suspected silicon at all. We genuinely believed in it,’ van Mierlo said. For 45 years, the learning curve has held steady-a it’s a fairly predictable line. Why is it going to stop? ”
When I asked van Mierlo about this obvious move to tandem and shared my reservations about this technology direction, the CEO proposed that we embark on a small gamble on the commercial potential of the tandem. He predicts that by the end of 2022, the solar industry will see 2 GW of tandem solar on the market.
In reality, not only do I expect that many gigawatts of tandem will be sold before the end of 2022, but I am also sure that more than 50 per cent of the market share of our industry will be commanded by tandem in a decade,” van Mierlo said.” Is it that I do not believe in silicon’s long-term position anymore? No!-No! Actually, it is the incredible accomplishment of silicon that now makes tandem modules the next unavoidable phase. Silicon is the optimal candidate for the bottom cell in a tandem configuration with its low bandgap of 1.1 eV and its low cost. A silicon bottom cell in this role converts less than one-third of the energy absorbed by the light, but still bears 100 per cent of the cost of the cell.
Solar startups in parallel include:
- In order to build perovskite-on-silicon tandem solar cells and modules, Oxford PV has raised more than $140 million. Meyer Burger collaborated with the start-up to build equipment and took an ownership stake in the venture as well.
- In order to make tandem panels, Swift Solar stacks perovskite solar cells. These layers may be placed on lightweight substrates and foils by the firm.
- The goal of Tandem PV is to print thin-film perovskites on a glass plate monolithically and stack them on top of silicon cells mechanically.
- Other pioneers of Perovskite solar technologies include Saule Technology and HPT.
