A multilayer composite includes a metal substrate layer, an electrically insulating layer directly disposed on the metal substrate layer, and a light absorbing layer directly disposed on said electrically insulating layer. In one embodiment, the light absorbing layer includes carbon black. This multilayer composite is bifunctional having the characteristics of both energy generation upon the absorption of electromagnetic radiation of the solar spectrum (making it useful as the photovoltaic component of a solar cell) and electrical energy storage. Therefore, in one embodiment, the multilayer composite is included in a solar cell.
