Photo by rubensalgadoescudero | Chinecherem Joseph Okoli-Onumazi, 21, administers a rapid antigen test to a local resident at Holzmarkt 25, one of Berlin’s renowned nightlife spots. Last summer the city invested in providing free testing around town. Joe, as he's known, works for Coronabike, a locally developed and government-subsidized company that does mobile testing seven days a week. Passersby can be tested free of charge by trained staff and receive results within 15 minutes. The testing facilities all use solar lanterns to illuminate their workspace once the sun goes down. This portrait demonstrates the work that these employees have done on a daily basis to help reduce risk at public gathering spaces. This is the latest chapter of my long-term project, Solar Portraits, which focuses on the impact of solar power in communities.
