Mallinckrodt Baker Adds Two PV Chemistries To Solar Cell Surface Modifiers


Covidien says that its Mallinckrodt Baker division has expanded its solar cell surface modifier product portfolio with two photovoltaic chemistries.

The new PV-162 and PV-200 solar cell surface modifiers will enhance solar cell efficiency by up to 0.7% absolute, increasing cell energy output for both in-line and batch solar cell manufacturing processes, according to the company.

The PV-162 solar cell surface modifier, a second-generation post-emitter surface modification product, builds upon Mallinckrodt Baker's PV-160 chemistry. A 100% water-soluble formulation requiring no intermediate rinse, PV-162 solar cell surface modifier increases cell efficiency by reducing charge recombination, the company says. The reduction in charge recombination results in higher open circuit voltage, short circuit current and fill factor.

The PV-200 solar cell surface modifier extends the efficiency-enhancing benefits of post-emitter surface modification to batch processes, which use phosphorus oxychloride doping technology. As with PV-162 chemistry, this increase is achieved by reducing charge recombination, resulting in increased open-circuit voltage and short circuit current.

The PV-200 solar cell surface modifier's tunable etch gives process engineers the ability to optimize the product's performance in their manufacturing process and achieve maximum cell efficiency gains. Its low bath temperature, between 20 degrees C and 40 degrees C, reduces energy expenditures while providing extended bath life, reducing overall cost of ownership, the company adds.
