NOVELTY - The module (1) has a main body provided with a negative terminal (5) and a positive terminal (6), where parallel connection (3, 4) of sub-modules (2) is connected to the negative and positive terminals. Each of the sub-modules comprises a string of series-connected back-contact cells. The cells of each sub-module are arranged in an array. The parallel connection and connections for the string of back contact cells are provided in a rear conductive sheet. The sheet comprises designated areas for the parallel connection corresponding to edge parts of the corresponding sub-module.    USE - Photovoltaic (PV) module such as building applied PV (BAPV) module and building integrated PV (BIPV) module, for use in shade-tolerant PV appliances and PV systems on roofs of a building.    ADVANTAGE - The module provides interconnections between the cells on the rear conductive sheet of the photovoltaic module so as to increase efficiency both in operation and during manufacturing. The module avoids need for bypass diodes for providing improved performance under partial shading conditions, and ensuring better shade tolerance of the PV module, thus reducing cost due to absence of bypass diodes made possible by parallel interconnection and better shade performance. The module allows module shapes and enables coverage of roofs with different panel shapes for allowing positioning nearby/around obstacles i.e. chimneys, thus enhancing freedom in roof coverage and achieving improved building aesthetics. The module allows efficient power production from the roofs, and can be tuned for standardized voltage regardless of module shape or size for enabling DC-DC converters or micro-inverters optimized for particular voltage.    DETAILED DESCRIPTION - The rear conductive sheet is a single rear conductive sheet. The back-contact cells are metal wrap through (MWT) cells, emitter wrap through (EWT) cells and interdigitated back contact (IBC) cells. The parallel connections are bussing leads.
