Trina Solar continues to push the abilities of multicrystalline silicon, today announcing the first multi c-Si solar PV cell with an efficiency of over 21%.

The company’s State Key Laboratory of PV Science and Technology of China has produced a new world record 21.25% efficient PV cell, as verified by Fraunhofer ISE.

The 156 square millimeter cell was fabricated on a p-type multicrystalline substrate, and integrates Trina’s Honey Plus technologies including back surface passivation and local back surface field.

This beats the previous record of 20.76%, which Trina set in late 2014. The company says that only low-cost industrial processes which can easily be integrated into high-volume production were used to fabricate the cell.

    And that shifts the goal posts further away from coal and the grid.

    A small increase in efficiency as one would expect with relatively new technology, just cast your minds back to the first solar cells with an output of 4% efficiency.
    Yes there are cells that cost a heap that are better however the slow increase is helpful to a final delivery of every lower price for the end product.
    One does not have to mention the cost to a consumer for a PV installation which is now in the range of buying a few consumer items.
    I see every day more PV being installed on houses all the time.
    I hope they are across the incoming LV from my experience it may be something to take a note of.
