PLANT PV, a photovoltaic materials innovator, announced today at SNEC 2017 a breakthrough that enables solar cell manufacturers to capture substantially greater solar cell power output. PLANT PV’s new Silver-on-Aluminum paste is designed for easy implementation with no added investment cost for cell producers and leads to a 1% increase in relative power output for c-Si solar cells.
Silver-on-Aluminum paste provides cell manufacturers with the ability to print the paste directly onto dried aluminum film, allowing them to cover the entire back of the wafer with aluminum paste and obtain the beneficial passivation of a continuous aluminum back-surface field.
PLANT PV recently demonstrated a 0.15% absolute efficiency gain over cells using conventional rear-tabbing pastes on multi-crystalline silicon solar cells at Fraunhofer ISE in Freiburg, Germany. The company, which was incubated out of the Molecular Foundry at Lawrence Berkeley National Laboratory, will present its Ag-on-Al paste concept and test results at this week’s SNEC 11th International PV Power Generation Conference in Shanghai.
