For photovoltaic systems that are integrated into buildings (building-integrated photovoltaics, BIPV), the aesthetical properties are crucial. While PV-modules based on crystalline silicon solar cells typically feature a geometrically regular and usually very technical appearance, architects and designers demand more freedom of design for PV-modules. Simultaneously, the electric efficiency and yield should stay in the focus when developing aesthetically valuable modules. In this work, we present a novel BIPV module concept aiming at high efficiency and innovative design. The novel concept is based on the idea that a PV cell can also consist of several parts that are electrically connected in parallel. These parts can vary in size and form and can be combined to cell clusters, strings and modules using a wire-based interconnection approach. Using glass-glass modules, the semi-transparency can be adapted to specific applications. A large variety of geometrical designs is possible, and the modules can be aesthetically integrated into the design of a building’s envelope. In the project Design2PV, we developed this concept, manufactured and characterized prototype modules, developed an electrical simulation tool that can automatically calculate the electrical properties for a given design and prepared a first demonstration site.
