Abstract/Summary:

---

Aiming at obtaining reliable values on power loss and gain in PV modules, this work systematically investigated the effective impact of both established PV technologies and newly suggested improvements in a number of different combinations. Using different measurement approaches, this systematic investigation was first done using single-cell mini-modules. Referencing against the power generated by the respective cell alone, the effects of the various manufacturing stages were analysed. The different PV module components - PV cell, ribbon, encapsulation material, glass and backsheet – were varied, including new approaches like light capturing glued ribbons (LCR™) and antireflection coated glasses. The results then were compared to full 60-cell modules, to both validate the results of the mini-module series and evaluate the effect of a multi-cell vs. a single-cell arrangement. Additionally the results were measured against plausibility calculations.
