HI-PROSPECTS - HIgh resolution PRinting Of Solar Photovoltaic EleCTrode Structures

点击翻译按钮获取中文摘要

PV OEMs face continued pressure to reduce the cost/W of solar cells. Additionally, they face significant price volatility andoverall cost for Ag electrode structures. Second and third generation PV cell manufacturers also face high costs for ITOand high performance TCO coated glass. Therefore technologies that enable cell efficiency gains and that facilitate thereplacement of expensive materials with cost effective alternatives generate strong business opportunities. The HIPROSPECTSteam will deliver a high resolution (< 3 microns) electrostatic ink jet (ESJET) technology capable of printingcost effective nano Cu front contact electrodes for Si cells and fine line Cu grid structures as a cost effective alternative toITO. In addition, the team will develop Si-Perovskite tandem cells with an efficiency of up to 26% at a cost < £230/ kWp.
