Optimizations of high-efficiency silicon heterojunction solar cells for tandem applications

Silicon heterojunction (SHJ) solar cells have exhibited efficiencies well above 25%. To further boost the efficiencies of c-Si-based solar cells, high-bandgap perovskite cells are stacked on top achieving a record efficiency of 29.52%. However, as most of the high-quality perovskite films are solution-processed, the front surface of the bottom...

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...
