Nanocrystalline Silicon Oxide Stacks for Silicon Heterojunction Solar Cells for Hot Climates

Haschke, J.; Monnard, R.; Antognini, L.; Cattin, J.; Abdallah, A. A.; Aissa, B.; et al. (2018)

Today, solar cells are generally optimized for 25 degrees C, whereas in most climates, especially hot and sunny ones, the operating device temperature is usually much higher, e.g. in the range of 60 degrees C. We investigate ...
Record-Efficiency n-Type and High-Efficiency p-Type Monolike Silicon Heterojunction Solar Cells with a High-Temperature Gettering Process

Kivambe, M. M.; Haschke, J.; Horzel, J.; Aissa, B.; Abdallah, A. A.; Belaidi, A.; et al. (2019)

We report independently confirmed 22.15% and record 22.58% power conversion efficiencies for thin (130-140 mu m) p-type and n-type monolike Si solar cells, respectively. We comparatively assessed advanced n-type and p-type ...
