In keeping with recent years, Taiwan-based solar cell manufacturer Neo Solar Power (NSP) is launching several new cells that follow a different path to high-efficiency, while claiming to be the low-cost option. Being showcased at EU PVSEC in Frankfurt next week is NSP’s polycrystalline Super18 solar cell and its mono-crystalline Black19+ with a maximum efficiency of 19.4%, all accomplished without the use of selective emitters or rear-side passivation technologies.
According to NSP, its six inch Super18 solar cell has a maximum conversion efficiency of 18.3%, with the expectation that a 60-cell module verified by TÜV would have an average output reaching 260W. A Black19+ solar cell array of 60 cells would have an average output of 270W, according to the company.

NSP said that it had implemented a new design and integrated new materials to develop the Super18 cell. The company reiterated that they had been working on techniques that significantly reduce potential-induced degradation (PID), while also working on providing cells with better low-light performance.
On a recent visit to NSP by Ellen Kullman, CEO of major materials supplier DuPont, noted that NSP was the first customer to adopt DuPont’s Solamet PV17F photovoltaic metallization paste that supported the introduction of its latest solar cells as well as other unidentified materials from the supplier.
“Founded on core values, DuPont has been a successful business for over two centuries which is a role model for NSP,” said Dr. Quincy Lin chairman, NSP.
“DuPont supplies a broad portfolio of materials designed to increase solar cell efficiency, module lifetime and lower overall system costs. All these contribute to reaching grid parity faster, and address one of the key global challenges: reducing dependence on fossil fuels. Key technologies such as photovoltaic metallizations are leading the way in boosting solar cell efficiency to new heights.”
