Trina Solar presented a new Perovskiet-Silicon Tandem solar module Prototype last week during the SNEC international photovoltaic power generation and smart energy exhibition in Shanghai, China.
The panel has a general module efficiency of 27.1% and is based on 210 mm tandem cells. Trina said that the low temperature of connection technology used to achieve higher optical use and to reduce resistance loss.
The manufacturer said that the temperature coefficient of the new product is 20% lower than that of heterojunction modules.
More technical details about the prototype were not announced.
In March, Trina Solar’s National Key Laboratory of Photovoltaic Science and Technology said that the newly developed Perovskiet-Polysilicon Tandemmodule had achieved a peak power of 808 W carried out in tests carried out by Tüv Süd.
The module, built on a 210 mm silicon wafer and the measurement of 3.1 m², was the first industrial standard PV module worldwide to surpass 800 W, the manufacturer said at the time, without providing further details.
The company also said in April that it had achieved 31.1% efficiency in a 210 mm industrial perovskiet-silical cell. A few days before Snec it said that it achieved 30.6% efficiency in a toothing module of 1,185 cm².
