China’s Trina Solar has unveiled a perovskite‑silicon tandem solar module prototype delivering 841 W and 27.1% efficiency, based on 210 mm tandem cells.
Trina Solar presented a new perovskite-silicon tandem solar module prototype last week during the SNEC International Photovoltaic Power Generation and Smart Energy Exhibition in Shanghai, China.
The panel has an overall module efficiency of 27.1% and is based on 210 mm tandem cells. Trina said it used low-temperature connection technology to achieve higher optical utilization and reduce resistance loss.
The manufacturer said the new product’s temperature coefficient is 20% lower than that of heterojunction modules.
More technical details on the prototype were not disclosed.
