Looking past PERC solar cells

While the adoption of large-format wafers has driven a wave of capacity expansion for PERC, existing manufacturers and new entrants continue to evaluate TOPCon and HJT. An increasing number of HJT pilot lines and gigawatt-scale capacity expansion projects are appearing, as manufacturers see the advantages of fewer process steps, higher efficiency ratings, and better yield rates. The localization of equipment is also a driving factor. PV InfoLink’s Derek Zhao offers an update on the latest developments and process routes for HJT.

US solar market in flux

Next year will set new records for the U.S. solar market, with 30.4 GW of installations expected. The utility-scale PV pipeline in 2022 is nearly 50% greater than 2021 and 2023, due to the combined effects of pandemic-related supply chain impacts, the solar Investment Tax Credit schedule, and other module procurement challenges. Over the next two years, solar installations will be concentrated in Texas, California, Ohio, Indiana, and Nevada, with large portions of the pipeline being developed by a few key players in each state. IHS Markit’s Eric Wright takes a closer look.
