Sungrow’s new power optimiser has a rated input power of 600 W, a maximum efficiency rating of 99.4%, and a weighted efficiency of 98.8%. It can accommodate up to 30 modules per string.

GoodWe plans to bring a range of building integrated photovoltaics (BIPV) products to Australia, announcing a partnership with specialist Umax Energy. The manufacturer this month released the details of its lightweight new panel, and plans to introduce an integrated solar roof tile to the Australian market.

Chinese researchers have developed a solar cell using CsSnI3 perovskite, known for its unique phase transitions and near-IR emissions. By simulating the device with various electron transport layers (ETLs) and hole transport layers (HTLs), they determined that the optimal cell could be created using a titanium oxide (TiO2) ETL and a nickel(II) oxide (NiOx) HTL.

An influential Australian union will propose a “significant, punitive tax” on the export of raw critical minerals as a means of promoting more value-adding onshore. The news comes as longstanding trade allies voice criticism over Australia’s growing momentum towards domestic manufacturing.

Battery companies hoping to get a foothold in Australia’s rapidly growing storage market were the main exhibitors at the Smart Energy Conference held in Sydney last week, outnumbering solar companies almost two-to-one. Pv magazine Australia looked at what is on offer and who the new hopefuls in the battery space are.

While Australia’s home battery market seems to have attracted most of the interest from newcomers, there has been some significant new developments in the commercial and utility-scale space. Pv magazine Australia examined the new products and companies in the commercial and utility battery storage space on display at the Smart Energy Conference.

An international research group led by Longi Central R&D Institute has published a paper describing Longi’s heterojunction solar cell based on a full-size silicon wafer that made a sensation in November, as it beat the long-lasting efficiency record held by Japanese manufacturer Kaneka for years. The researchers attributed the cell efficiency improvement to the implementation of a p-type amorphous silicon hydrogenated layer together with a modified transparent conductive oxides contact, which they said greatly reduced the cell contact resistivity.

JinkoSolar, Long, JA Solar, and Trina Solar have all reported impressive growth figures for the first quarter of this year.

Zhengrong Shi and his company, Suntech, are true pioneers of the Chinese solar industry. While Suntech burned bright, and eventually flamed out, under Shi’s leadership, the company’s solar ecosystem and innovation persist as China’s PV market surges past 100 GW(AC) today.

China reached 327.4 GW cumulative installed PV capacity at the end of February, according to new figures from the National Energy Administration (NEA).
