NOVELTY - A photovoltaic cell module comprises several of serially connected photovoltaic cells on a common substrate, each containing a first electrode, a printed light-harvesting layer and a printed second electrode, where at least one of electrodes is transparent, and where the second electrode of first cell is printed such that it forms electrical contact with the first electrode of an adjacent second cell without forming an electrical contact with the first electrode of the first cell or the light-harvesting layer of the second cell.    USE - As photovoltaic cell module used in the item such as a hat (claimed).    ADVANTAGE - The Photovoltaic module of serially connected photovoltaic devices has a simple construction. The photovoltaic cells are formed as nested loops, such as concentrically-arranged loops, which permits a cell module to be formed in a wide range of desired shapes while only requiring two terminals, thus this device can be made to match the surface available while maximizing the power output. The device has transparent first electrode is the cathode, which avoids the use of low work function metals as electrodes, thus improves the stability of the device.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for following:    (1) making a photovoltaic cell module involving forming a first electrode layer for each cell on the common substrate; printing a light-harvesting layer for each cell over the first electrode layer; printing a second electrode layer for each cell over the light-harvesting layer such that the second electrode layer of a first cell forms an electrical contact with the first electrode layer of an adjacent second cell without forming an electrical contact with the first electrode of the first cell or the light-harvesting layer of the second cell;    (2) an item comprising the photovoltaic device, a power consuming device and/or power storing units; where the power consuming device is a radio, and the power storing units is a rechargeable battery.
