Market Survey On Metallization Pastes

Overview on Solar Cell Contacting Technology And Product Specs Of Latest Pastes

Market Survey On Metallization Pastes

Metallic pastes, taking the role of electrical contacts on solar cells, have always been at the epicenter of discussions concerning improvements in PV. Pastes not only influence solar cell’s performance characteristics considerably, they equitably affect the manufacturing costs of cell processing. While cell efficiencies ranged around 16 to 17% about 10 years ago, today typical solar cell efficiencies have reached around 20%, but there are already mono PERC cells in production that exceed 22%.

For our market survey on metallization pastes, 14 suppliers, including the market leaders, provided the data for 122 products. These paste models are listed under 7 different categories –

  • Front contact silver pastes (p-type)
  • Silver pastes for double or dual printing (p-type)
  • Rear tabbing silver pastes
  • Aluminum pastes for Back Surface Field (BSF)
  • Pastes for Passivated Emitter and Rear Cell (PERC) architecture
  • Pastes for n-type cells
  • Low temperature curable pastes, typically used for heterojunction cells and some thin-film PV

The 14 companies answering our market survey are mainly from China. Even those 5 that are not originally Chinese companies – Heraeus from Germany, DuPont from the United States, Monocrystal from Russia and Samsung and Phoenix Materials from Korea – are usually manufacturing in China, where the bulk of the cell manufacturers is located.

  • DK Electronic Materials Co, China
  • DuPont, US
  • Environmental Natural Chemicals (ENC), China
  • Heraeus, Germany
  • Hunan National Silver New Materials Co.,Ltd (HNSNM), China
  • Jiangsu Hoyi Technology Co., Ltd, China.
  • Monocrystal PLC, Russia
  • Phoenix Materials Co., Ltd, Korea
  • Samsung SDI, Korea
  • Shanghai Transcom Scientific Co., Ltd., China
  • Soltrium Advanced Materials Technology, China
  • SZ Glory New Materials, China
  • Zhejiang Gonda Electronic Technology Co., Ltd, China
  • Zhejiang LongSun Electronic Technology Co., Ltd, China

Shravan Chunduri is Head of Technology at TaiyangNews. Shravan caught the solar bug vey early in this career, starting 20 years ago in research, followed by solar manufacturing, then writing and consulting. At TaiyangNews his responsibility spans from writing technology articles and reports. He also works as a solar consultant for MISCHCO. Until 2014, Shravan was a Technology Analyst at Photon International, where he worked for 7 years, covering everything from silicon to solar module technology. Before moving into writing, he was a Technology Officer at Indian Module maker PT Solar and Process Engineer in solar cell manufacturing at Microsol in Fujairah. Shravan first taste of the “solar mother milk” roots back to his time at the Research Center Juelich, Germany, where he worked as Research Associate.Shravan holds a B.Sc. from Wesley College in Hyderabad, India and a Master of Science in Renewable Energies from the University of Applied Sciences in Aachen, Germany.
