1 Pioneering The Next Generation of Solar Energy

2 Sol Voltaics - Two Core Technologies Vertically aligning and contacting the nanowires to form a module size PV film 2 Production of low-cost GaAs solar cell nanowires via Aerotaxy

3 Sol Voltaics Power Products TANDEM MODULE (Sol Film on Si on Roof) BIPV (SolFilm Window) SINGLE JUNCTION MODULE (Sol GaAs Film) Efficiency >25% Costs Wp comparable to 19% PERC cells Efficiency 10-20% Efficiency >21% Lowest cost on the market 3

4 SolVoltaics Tandem Product GaAs Module size, SolFilm GaAs Nanowire solar cell film...in their module GaAs c-si CIGS/Si cell/module 4 Brings a 19% CIGS/Mc-Si module to 27% efficiency or a 23% C-si module to 29% efficiency

5 III-VS on Si Tandems NREL/CSEM Planar Stacked Tandem NREL/CSEM research Nanowire Stacked Tandem Sol Voltaics AB product GaAs GaAs c-si Expensive 26.8% Top Cell 32.8% stacked Eff c-si Low cost 15.3% Top Cell (to date) [S.Essig et al., Nature Energy 2, (2017)] published in IEEE JPV 5 - Stacked III-V on Silicon = Proven technology to over 30% - Industry leading costs enabled by Sol Voltaics nanowire production methodology called Aerotaxy

6 New Hire Sr. Device Characterization Engineer Dr. Stephanie Essig - Postdocs at EPFL, ANU, NREL - PhD from Fraunhofer ISE - Author of all papers with WR tandems with III/V and silicon (29.6%, 30.6% & 32.8% published) 6

7 Tandem Module Simple Integration NW FILM EVA, J-BOX TANDEM MODULE NW FILM placed on top of Si MODULE MODULE (BSF, PERC, CIGS) 7

8 SolFilm Shingle/Window SolFilm produced as thin glass-glass sandwich Sandwiched between clear glass Or with textured glass 8

9 SolFilm Products (cont.) - BIPV GaAs Nanowire solar cell film, Variation in no. of NW/area Module size, Sol Film 9

10 Single Junction SolFilm Modules Most basic module design Standard glass-glass or lightweight Module can be bifacial (transparent back contacts) or mono-facial (internal reflector) Using standard TF module technologies Lowest cost per Wp 10

11 Clear Roadmap to 35%-40% Efficiency Dual nanowire films on Si for 30-40% efficiency range Dual junction nanowires on Si for 30-40% conversion efficiency range GaAsP GaAs GaAsP GaAs CIGS/c-Si Dual NW film on Si CIGS/c-Si Dual Junction NW on Si 11

12 Why GaAs? 12

13 Why Gallium Arsenide? Highest efficiency solar cell material in the world 28.8% single junction world record. High stability Used in satellites & concentrators Inorganic material, comparable/compatible to silicon 13 Excellent high temperature and low light behavior More electricity with equal Wp

14 Power Benefits of GaAs Low Temperature Coefficient Middle East Higher radiation means that panels heat up more in the sun in ME than in EU Irradiation between 2000 and 2800 kwh/m 2 a year 14

15 Middle East Power Out Sol Voltaics GaAs vs Si Si 18.5% GaAs SJ 18.5% GaAs SJ 22% Wp panels Cost/Wp panel $0.25 $0.25 $0.25 Cost/Wp field $0.85 $0.85 $0.78 Number panels Nameplate MWp 1 MW 1 MW 1.18 MW Temp coefficiency -0.4 %/K -0.1 %/K -0.1 %/K kwh output year kwh/y kwh/y kwh/y Increase kwh in % - 19% 41% 15 - In calculation, temperature Si module in 75 C and of GaAs module 70 C (GaAs operates at a lower temperature than Si.) - Irradiation is 2200 kwh/year m -2 - Not taken into account improved light absorption at non-ideal angles and at low light conditions additional benefits of NWs
