Photovoltaic devices such as solar cells, hybrid solar cell-batteries, and other such devices may include an active layer having perovskite material and copper-oxide or other metal- oxide charge transport material. Such charge transport material may be disposed adjacent to the perovskite material such that the two are adjacent and/or in contact. Inclusion of both materials in an active layer of a photovoltaic device may improve device performance. Other materials may be included to further improve device performance, such as, for example: one or more interfacial layers, one or more mesoporous layers, and one or more dyes. |
