A multicolor photovoltaic electrochromic apparatus is provided, including a first transparent substrate, a second transparent substrate opposite to the first transparent substrate, a photovoltaic electrochromic device on the first transparent substrate, and a chromogenic device between the first and the second transparent substrates. The photovoltaic electrochromic device includes thin-film solar cells and an electrochromic material on the thin-film solar cells. The thin-film solar cells have different potential differences, and each of the thin-film solar cells includes an anode, a photoelectric conversion layer, and a cathode. The chromogenic device includes two electrodes and a chromogenic material thereon. The cathodes of the thin-film solar cells, which have distinct potential differences, are connected to the first electrode and the second electrode of the chromogenic device respectively.
