Rutger Schlatmann, Head of Solar at Helmholtz Center Berlin, will be delivering the keynote presentation at the TaiyangNews Next-Generation PV Technology 2026 Virtual Conference. He will address the next efficiency frontier, and the role perovskite tandems will play in shaping the future of photovoltaics.
By combining complementary absorber materials, tandem structures allow a broader portion of the solar spectrum to be utilized, breaking the barriers of single-junction devices. The research community has made significant strides, and Schlatmann will take us through on what comes next.
Scheduled for April 22, 2026, from 09:30 to 13:00, participation in the event is free and can be done here.
Heterojunction (HJT) manufacturer Boamax has sold HJT module production equipment and related assets held by its subsidiary Inner Mongolia Baoxin to Otog Banner Chengzhen, a local state-owned asset management firm, for RMB 50.23 million.
The assets had a book value of RMB 78.53 million and were under court seizure after depreciating by about 36%. The proceeds will be used to offset RMB 138 million in equity repurchase obligations.
Boamax has reported losses for 11 consecutive quarters and expects a net loss of RMB 60 million to RMB 100 million for 2024. The company is also under investigation for alleged violations of information disclosure requirements, faces multiple legal disputes, and is at risk of being delisted (see China Solar PV News Snippets).
Shaanxi Province has released its 15th Five-Year Plan, targeting total renewable energy capacity of 120 GW by 2030, including over 100 GW of wind and solar and 5.4 GW of pumped hydro storage.
The plan prioritizes large-scale PV development in the northern Loess Plateau and promotes ‘PV+’ models such as forest-PV and tea-PV integration in southern regions. It also aims to develop 30 counties with more than 1 GW of diversified renewable capacity and expand ‘new energy + storage’ systems, including lithium-ion, vanadium flow, and compressed air storage technologies.
Inverter and ESS supplier Sineng Electric has announced the grid connection of a 300 MW/1200 MWh independent shared energy storage plant in Zhangye, Gansu Province.
Located in the Hexi Corridor, the project uses a 4-hour storage system to address renewable curtailment and peak-shaving needs. Sineng supplied 1,250 kW centralized PCS units to the project, featuring over 98.5% efficiency and improved battery cluster parallel performance, supporting millisecond-level response for grid services.
Recently, Sineng Electric completed on-site joint commissioning tests of its ‘single-transmission, dual-reception’ inverter solution in Heze, Shandong province (see China Solar PV News Snippets).
Shandong Province has issued its 15th Five-Year Plan outline, targeting 200 GW of non-fossil energy capacity by 2030, with continued expansion of solar PV and supporting storage infrastructure.
The plan supports utility-scale PV on saline-alkali land and promotes self-consumption PV for large energy users. It also outlines development of pumped hydro, compressed air and electrochemical storage, including projects such as pumped hydro in Weifang and Tai’an, a vanadium flow battery base in Dezhou, and a 500 MW/2000 MWh molten salt storage project in Binzhou.
