Photovoltaics Moving into the Terawatt Age
In the last few years, PV electricity became cost-competitive with electricity produced by conventional sources. Global PV production capacity will reach in the next 2-3 years 100-120 GWp/a, doubling the production volume of 2016, soon bringing global PV installations into the Terawatt range. A key factor for this growth will be continuous technology advances aimed at higher efficiencies at reduced cost. In addition, cell efficiency will be even more important than lowest cost, to optimize energy harvest from a given area. Crystalline Silicon technology currently represents more than 90% of the global PV market. This technology is approaching a ceiling of 29% efficiency for a single-bandgap semiconductor. New approaches for higher efficiencies require heterojunctions, and several approaches will be discussed. These include heterojunctions on silicon, allowing to combine well-established large-scale Silicon PV technology with new technologies, such as low-cost III/V or Perovskite layers.
