Flexible semi-finished photovoltaic module

Method for manufacturing a semi-finished free-formable photovoltaic module for a three-dimension (3D) formed solar panel, the method comprising:

• providing a plurality of flexible photovoltaic elements (10), each flexible photovoltaic element comprising:
• a thin film photovoltaic stack disposed on a flexible carrier;
• a first polarity back terminal stretching out along a first portion of a back surface of the flexible photovoltaic element;
• and
• a second polarity front terminal including a front current collecting element disposed along a light receiving front surface of the photovoltaic stack, the front current collecting element having side-portions laterally protruding across a side of the photovoltaic stack to form a front contactable second polarity front terminal;
• folding the side-portions forming the front contactable second polarity front terminal at least in part back along the back surface of the flexible photovoltaic element to form a back contactable second polarity back terminal;
• disposing a plurality of flexible electrically conductive wiring elements in a pattern adapted to match a layout of the plurality of flexible photovoltaic elements comprised in the semi-finished free-formable photovoltaic module;
• placing the plurality of flexible photovoltaic elements in a layout matching the pattern such that the first polarity back terminal and the second polarity back terminal have an overlap with the respective conductive wiring elements;
• and
• encapsulating the disposed plurality of flexible electrically conductive wiring elements and the placed plurality of flexible photovoltaic elements, thereby fixating a relative laterally separated position of the plurality of flexible photovoltaic elements and the plurality of flexible electrically conductive wiring elements and thereby forming an electrically conductive interconnection between adjacent flexible photovoltaic elements.
