  • LONGi Green Energy mono PERC solar cell hits 22.71 percent efficiency

    The Fraunhofer ISE CalLab of Germany certified the photovoltaic conversion efficiency of 22.71 percent of LONGi Green Energy Technology Co.’s monocrystalline PERC cell, which is a new world record for this cell type. As the industry’s leading manufacturer of high efficient monocrystalline products, LONGi has always been committed to the improvement ofRead More — Solar Builder magazine

  • This new Silver-on-Aluminum paste could boost PV cell efficiency

    PLANT PV, a photovoltaic materials innovator, sent word about a breakthrough that enables solar cell manufacturers to capture greater solar cell power output and with no added investment cost for cell producers. “For 20 years the industry has had to accept an efficiency loss from printing silver bus bars directlyRead More — Solar Builder magazine

  • Trina Solar says it hit a new mono-crystalline PERC cell efficiency record

    Feels like its been awhile since a module manufacturer touted an efficiency record. The wait is over: Trina Solar Limited announced that its State Key Laboratory of PV Science and Technology of China set a new world conversion efficiency record of 22.61 percent for a high-efficiency p-type mono-crystalline silicon (c-Si)Read More — Solar Builder magazine

  • Researchers exceed the theoretical limit of silicon solar cells (hit 30.2 percent)

    So, get this: Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with the Austrian company EV Group (EVG) say they have successfully manufactured a silicon-based multi-junction solar cell with two contacts and an efficiency exceeding the theoretical limit of silicon solar cells. Tell me more! For thisRead More — Solar Builder magazine

  • Natcore Technology’s new solar cell design shows huge efficiency jump in 11 months

    Natcore Technology Inc. has achieved commercial-level efficiencies for its laser-processed solar cells. This refinement of Natcore’s all-back-contact silicon cell structure, which utilizes low-cost aluminum instead of high-cost silver, has progressed rapidly. Less than 11 months ago, early proof-of-concept cells were delivering 4 percent efficiencies. Today, the cells have already reached efficienciesRead More — Solar Builder magazine
