The integration of PV modules into building envelope or other applications in particular presents different constraints reducing their electrical performance compared to ground installations due to the change in their operating conditions. The objective of this PhD thesis would be the research of a global design method of a BIPV facade or roof in order to optimize its production and its impact on the integration system (building, etc.) by overcoming its constraints: static and mobile shading, temperature gradients due to low albedo, favorable solar radiation especially in cold periods, localized overheating… Different approaches will be considered:
1- Optimize the temperature management of the PV field or the uniformity of the temperature field by forced convection (with air or water as heat transfer fluid): case of a double skin facade (or roof) (extraction or recovery of heat from the rear face of the PV modules through numerical and experimental analysis of natural or forced ventilation paths (air flow) and case of a single wall facade (or roof) (with other cooling methods);
2- Passive cooling of BIPV and PV systems: research from numerical models and experimental studies and validation of simple passive technological solutions (fins, heat sinks, graduated materials, materials with photonic effect, among others).
