A photovoltaic cell includes: (1) a front contact; (2) a back contact; (3) a set of stacked layers between the front contact and the back contact; and (4) an encapsulation layer covering side surfaces of the set of stacked layers. At least one of the set of stacked layers includes a halide material having the formula: [AaBbXxX′x′X″x″X′″x′″][dopants], where A is selected from elements of Group 1 and organic moieties, B is selected from elements of Group 14, X, X′, X″, and X′″ are independently selected from elements of Group 17, a is in the range of 1 to 12, b is in the range of 1 to 8, and a sum of x, x′, x″, and x′″ is in the range of 1 to 12. |
