Example 2: Improved screen-print metal pastes. Example 3: Lowering manufacturing CapEx by kerfless wafering. Click to edit titleAverage S lar Resource Calculationenergy.gov/sunshot106The amount of power that is produced by a PV system depends upon the solar resource availability (in addition to other factors like temperature and snowfall), which is location dependent. The median solar resource for the United States is represented by Kansas City, MO, while the highest solar resource is represented by Daggett, CA, and the lowest solar resource is represented by Seattle, WA.PV System contribution to LCOE0.060.080.10.12LCOE($/kWh)1000 kWh/kW1500 kWh/kW2000 kWh/kWjinkosolar 1100.020.040 0.2 0.4 0.6 0.8 1 1.2 1.4LCOE($/kWh)System Cost ($/W)Minimum cell efficiency will be over 20%22%26.3%25.0%Best Cell Eff22.6%Ave. Cell Eff1320%18.5%21.6%mc-Si cell technology is still popular in 201614mc-SiMaterialsTypeB, Ga, GePCastingloadLarge grainSmall grainWire SawSlurryDiamondPurityUMGSG7nKerflessRibbonDipThin filmThickness140 um190 umSize5”6”8”CellStdSEPERCBifacialModuleStd cell1/6 OverlayWiremc-Si evolution15Mono2 sprayAcid texturingMCCTRIEHJTEWTTandemMWT23.5%IBC24.5%HBC22% lineIn general, higher efficiency come with a cost29%GaAsModule cost1622.5%HJTnPERLpAdvpStdGrid ParityCost reduction over years172017 status:Cell Ave: 18.7%Poly Si24%Module37%Cost sharejinkosolar 18P-60: 275 WASP: $0.37/WWafer16%Cell23%ASP($/W)Future cost reductionCellModule0.20.250.30.350.4Ag consumption Wafer thicknessAutomation Utility usagejinkosolar 19ASP($/W)Poly SiPoly SiWaferWaferCellModule00.050.10.152017 2020 Texturing Glasses Wire0.0800 0.0900 0.1000 0.1100 ASP($/W)jinkosolar 200.0500 0.0600 0.0700 17 19 21 23 25 27 29ASP($/W)Cell Efficiency (%)Volume production leads to cost reductionSummary Solar program targets cost not just efficiency The scale or volume production reduces the cost mc-Si technologies are marching toward the grid partyThank You23
