SERIS and Ruxing Technology aim to develop commercial metallization pastes to enable above 24 percent low-cost solar cell production

The Solar Energy Research Institute of Singapore (SERIS) and manufacturer of metallization pastes for PV products Guangzhou Ruxing Technology Development Company Ltd. have signed a collaboration agreement to accelerate the development of commercial metallization pastes to enable low-cost, mass production of above 24 percent solar cells. According to the organization, over the past 15 months SERIS and its industry partners have been fine-tuning SERIS’ proprietary »monoPoly« passivated-contact solar cell technology platform for mass production, with average solar cell efficiency range of 23.0 percent to 23.5 percent and 60-cells module power above 330 Watt. »With Ruxing Technology’s expertise in developing specialized, production-ready metallization pastes, SERIS expects to increase the average efficiencies of monoPoly solar cells to 23.5 to 24.0 percent range and module power beyond 345 W.«
The »monoPoly« technology platform is a »low-cost option to enhance PERC production line performance, requiring only one tool upgrade for most PERC production lines and having one production process step less than a standard PERC production process,« says SERIS and expects »at least 3 GW of monoPoly production capacity to be installed in 2019.«
Chinese Guangzhou Ruxing Technology Development Co., Ltd. is a manufacturer of conductive pastes for the photovoltaics industry. Founded in 2008 and located at the National University of Singapore (NUS), the SERIS is Singapore’s national institute for applied solar energy research.
