Textured back reflectors for thin-film silicon solar cells

The low conversion efficiency of thin-film silicon solar cells currently prevents them from competing, commercially, with the dominant crystalline silicon technology. The small thickness of the photo-active layer in thin-film silicon solar cells is an advantage for reducing raw material consumption and increasing industrial throughput, but...

Optical characterization of photovoltaic materials and structures for thin-film solar cells based on advanced texturization

Advanced texturization is a promising approach to increase the performance of thin-film solar cells. Currently, light trapping schemes implemented in state-of-the-art devices utilize randomly textured interfaces to increase their optical performance. Periodic gratings, however, have the potential to outperform their random counterparts and are...

Optimization of ITO TCO for thin-film silicon and HIT solar cells

Within thin-film silicon solar cells, the so-called Transparent Conductive Oxide (TCO) plays an important role. The optimization of TCOs is a very meticulous process since these thin layers not only need to be both highly transparent and conductive, but are also used for light management; that is manipulating the path of the light through the...
