摘要: Multi-junction solar cells (MJSC) operating at working conditions under concentration are subjected to temperatures (T) for which the optical coupling provided by their anti-reflective coatings (ARC) has not been optimized. High and wide ray angles produced concentrator on interface of cell can significantly modify ARC performance. This effect is especially pronounced ARCs adapted silicone encapsulant because refractive index (n) sensitive temperature, modifying optimal design thickness material composition. magnified tilted rays whose path length through layer most modified. In this work, an absolute external quantum efficiency (EQE) characterization system perform angular temperature spectral response analysis, allowing quantify impact mismatch caused increase each junctions. The intricacies upgraded technique explored, providing insight important unexpected measurement variables such as finger orientation with respect incident bundle. A significant between junctions due change in observed, leading short-circuit current (I SC ) losses high 6% (T=25°C) impinging tilt 70° more realistic operation 65°C. arise from subcells variations coupling. Lessons analysis may be taken into account future CPV designers.
