New product line aims for PV efficiency

A new line of PV products from Rohm and Haas is set to help increase solar cell efficiency across Europe.

Enlight photovoltaic products use innovative materials to improve the efficiency of solar cells, enhancing their ability to convert the sun’s light into electrical energy. The company’s technology also helps solar cell manufacturers more quickly produce their products.


Bob Ferguson, vice president and business unit director in Rohm and Haas Electronic Materials said: “Rohm and Haas entered the photovoltaic market in 2006 with unique technology that improves cell efficiency and increases manufacturing yield.

“Since then, we’ve worked with many leading photovoltaic companies to enhance and broaden our product portfolio. When you combine strong customer support, our passion for technical excellence, and the introduction of our newest Enlight products, we’re excited about what we can offer – and the material difference we can make – to the renewable energy industry.”

Enlight product solutions include:

• Enlight SilverPlate 620 for PV metallization offers an improved Light Induced Plating (LIP) solution over our first generation product. This new technology can increase cell efficiencies by as much as 0.6% compared to standard paste processes.
• Enlight JetResist 1310 for PV imaging is a hot melt ink that is compatible with most drop-on-demand inkjet systems. The product has resolution capability down to 60um and is compatible with most etches, including BOE, HF and cupric chloride.
• Enlight JetStrip 1210 Stripper is optimized to remove JetResist 1310 with fast stripping speeds. It can be used in either spray or immersion equipment configurations and will not attack underlying emitter layers.
• Enlight Wafer Clean 320 Series for PV cleaning has been optimized to allow for customized cleaning and etching performance while being compatible with mono-crystalline and multi-crystalline substrates.
