Perovskite/silicon tandem photovoltaics is a promising technology to exceed the performance limit of single-junction solar cells. For utility-scale photovoltaic plants, trends and forecasts indicate that bifacial modules mounted on solar trackers will increasingly dominate the market in the next 20 years. In line with this roadmap, we investigate the outdoor performance of perovskite/silicon tandem solar cells mounted on a horizontal single-axis solar tracker in an environment with elevated solar insolation and albedo. We experimentally demonstrate in such conditions that a bifacial monolithic tandem solar cell installed on a tracker can generate 55% more power than an equivalent tandem mounted on a fixed rack. On the basis of our results, we anticipate a significant economic advantage by coupling bifacial monolithic perovskite/silicon tandem technology with solar trackers.
