Building-integrated (BIPV) and building-applied (BAPV) photovoltaics demand solutions that balance power yield, form, and function. Our research addresses: - Design-performance trade-offs: How size, shape, color, and orientation affect energy output - Vertical & façade-specific conditions: Temperature, ventilation, and shading effects on CIGS, perovskite and crystalline Si modules - Innovative integration concepts: - PV-green façade hybrids - Concrete-integrated solar elements - Custom-shaped, colored, or translucent modules - Case Study: Our living lab for BIPV in Berlin-Adlershof features a 380 m² blue-tinted CIGS façade with 120+ sensing points, enabling detailed analysis of: - Rear-side ventilation & module temperature dynamics - Impact of microclimate on long-term performance - BIPV-specific degradation mechanisms
