A method of manufacturing a flexible photovoltaic module, comprising: preparing photovoltaic web material including a photoactive top layer formed of semiconductor material and a conductive sheet as a back contact layer; scribing the web material by removing semiconductor material down to the front side of the conductive sheet, thereby defining a series of discrete photovoltaic cell regions on top of the conductive sheet along the long axis of the web material, each cell region comprising at least one interconnection pad area defined on the front side of the conductive sheet and disposed on a long edge of each cell region; cutting entirely through the web material between adjacent cell regions, to partially singulate the cell regions wherein cutting entirely through the web material between adjacent cell regions includes forming cuts that extend most of the way across the web material in a direction perpendicular to a long axis of the web; applying a conductive grid pattern to a transparent front sheet, the grid pattern including multiple sub-patterns, wherein each sub-pattern corresponds to one of the discrete cell regions and comprises at least one interconnection tab corresponding to the pad area of the adjacent cell region; laminating the web material to the transparent front sheet with each grid sub-pattern being registered with one of the cell regions so that each interconnection tab of the grid pattern is registered with a corresponding interconnection pad area of the adjacent cell region, such that adjacent cell regions can be connected electrically in series via said interconnection tabs and pad areas; trimming edge regions of the web material to complete singulation of discrete cells, after laminating the web material to the transparent front sheet; and electrically interconnecting adjacent cells in series by electrically connecting the interconnection tabs to the corresponding interconnection pad areas. preparing photovoltaic web material including a photoactive top layer formed of semiconductor material and a conductive sheet as a back contact layer; scribing the web material by removing semiconductor material down to the front side of the conductive sheet, thereby defining a series of discrete photovoltaic cell regions on top of the conductive sheet along the long axis of the web material, each cell region comprising at least one interconnection pad area defined on the front side of the conductive sheet and disposed on a long edge of each cell region; cutting entirely through the web material between adjacent cell regions, to partially singulate the cell regions wherein cutting entirely through the web material between adjacent cell regions includes forming cuts that extend most of the way across the web material in a direction perpendicular to a long axis of the web; applying a conductive grid pattern to a transparent front sheet, the grid pattern including multiple sub-patterns, wherein each sub-pattern corresponds to one of the discrete cell regions and comprises at least one interconnection tab corresponding to the pad area of the adjacent cell region; laminating the web material to the transparent front sheet with each grid sub-pattern being registered with one of the cell regions so that each interconnection tab of the grid pattern is registered with a corresponding interconnection pad area of the adjacent cell region, such that adjacent cell regions can be connected electrically in series via said interconnection tabs and pad areas; trimming edge regions of the web material to complete singulation of discrete cells, after laminating the web material to the transparent front sheet; and electrically interconnecting adjacent cells in series by electrically connecting the interconnection tabs to the corresponding interconnection pad areas.
