Growth Of TOPCon Technology

• TaiyangNews Top Modules List in January 2022 featured 2 TOPCon products, accounting for 10% share of all the products listed
• The product count of TOPCon modules increased to 8 by December 2022, and its share rose to 24%
• At the end of 2023, 18 TOPCon products were part of the listing, increasing their share to 33%, making it the only cell technology stream that increased its product share over the 2-year period.

TOPCon has had quite a journey in the solar energy market, rapidly expanding its product offerings and increasing its market share significantly over a 2-year period. This cell technology, which  had little presence with only 2 products in January 2022, quickly entered the commercial space and to reach 8 products by December 2022. Over this period, its share increased from 10% to 24%. By the end of 2023, TOPCon had 18 products listed, translating into a share of 33%. It's the only cell technology stream that has increased its product share over the 2-year period (see Share Of Cell Technologies).

In January 2022, we first listed products from JinkoSolar and Jolywood, which remained the only pair of TOPCon module makers that could offer higher efficiency products. Qcells and Astronergy joined in with their TOPCon products in May of 2022. In August, EGing PV also joined the stream, followed by JA Solar, DAS Solar and Trina, which also commercialized TOPCon modules that were reflected in the September 2022 listing. However, in the subsequent 2 months, Qcells' product lost its place in the list as its data was not accessible, to only become available again in December 2022.

All above 22%: By the end of 2023, all the 18 TOPCon module products listed had an efficiency above 22% with JinkoSolar taking the top seed at 22.65% for most of the year, while Astronergy joined in at the end (Source: TaiyangNews).

The next change happened in March 2023 when 2 more companies – Tongwei and Canadian Solar – started offering TOPCon modules commercially. With these additions taking the listed products to 10, the technology's share increased to 27%. However, in June 2023 again, Qcells' product was removed from the company's website, consequently also from our listing. The product count still remained at 10 with DMEGC's product entering our listing for the first time the same month (see Top Efficiency Of Each Cell Technology).

In July, 5 modules were included from companies using their own TOPCon cells – Qn-SOLAR, Suntech, GCL-Si, Runergy and SolarSpace. Then URECO joined the stream in August, followed by Yingli and CECEP in October. The total product count increased to 18 through these additions and remained unchanged till the end of 2023, as did TOPCon's share of 33%.
