JinkoSolar today announced a record high efficiency of 24.2% was achieved by its large-area n-type TOPCon monocrystalline silicon solar cell. Testing was conducted by the Photovoltaic and Wind Power Systems Quality Test Center at the Chinese Academy of Sciences (CAS).
TOPcon (Tunnel Oxide Passivated Contact) is a newer solar manufacturing concept where a thin oxide layer is introduced to the silicon cell to reduce recombination losses and increase cell efficiency.
The large-area N-Type cell features JinkoSolar’s “HOT” cell design, which is based on the tunnel oxide passivating contact technology. JinkoSolar’s high quality n-type wafer, selective doping technology and advanced fine-line printing technology allow the company to achieve 24.2% cell efficiency across its entire product chain. The world PV module power record of 387.6 W for n-type half-cell module was fabricated using JinkoSolar’s HOT cell design.
N-type HOT technology is a key R&D milestone for JinkoSolar and is opening up a new path toward developing high-efficiency industrial products. N-type HOT technology also demonstrates the competitiveness of JinkoSolar products when compared to current HIT and IBC technologies.

what is the availability and cost of n-type wafer compared to p-type wafers? I know that n has smaller market share as p. Will that change? why?

Hi Robert,
I completely agree. It seems as though no one has a reliable, proven system to do exactly that.

Woooow am so amazed and already excited to use this wonderful technology for such a high perfomance..keep up the fighting spirit in this competitive field

Why are solar companies so reluctant to put wind power with their systems when I talked to solar Representatives that want to install the solar panels they don’t want to hook up a wind generator let’s face it The Best of Both Worlds when the sun’s down and was always win no matter how can they claim to be so high-tech when they when they don’t even try to hook up a wind generator with the system
