TL;DR: In this article, three independent approaches to improving the performance of Micromorph® tandem solar cells are presented. But none of these methods can achieve the state-of-the-art performance of the current state of the art for thin film silicon solar cells.

TL;DR: In this article, a first draft of novel rather flat scattering superstrates with an optimized high bandgap amorphous silicon top cell including a carbon-free buffer at the p/i interface is presented, and careful optimization of the interfaces (including suboxide doped layers and buffers) and of the bulk crystallinity of the middle and bottom microcrystalline subcells allowed to reach a stabilized efficiency of 13.5 % (after 1000h light-soaking, internal measurement).

TL;DR: In this article, rough etched glass substrates were used to decrease the sheet resistance of zinc oxide layers grown on it and showed improved light trapping potential compared to ZnO films grown on flat glass.

TL;DR: In this article, the effect of the transparent conductive oxide (TCO) layer roughness on the reflection spectrum of the SiC tandem cells is studied. But the authors focus on the impact of the intermediate reflector on the performance of SiC.
