Energy Yield in Hot and Sunny Climates: Impact of Silicon Solar Cell Architecture and Cell Interconnection
Haschke, J.; Seif, J. P.; Riesen, Y.; Tomasi, A.; Cattin, J.; Tous, L.; et al. (2017)In this work, we investigate the temperature and irradiance dependencies of the power output of silicon solar cell architectures (BSF, PERC, PERT, SHJ). When we compare our data with commercial module datasheets, we find ... -
Lateral transport in silicon solar cells
Haschke, J.; Christmann, G.; Messmer, C.; Bivour, M.; Boccard, M.; Ballif, C. (2020-03) -
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 ... -
Silicon Heterojunction Solar Cells on Quasi-mono Wafers
Haschke, J.; Kivambe, M. M.; Horzel, J.; Monnard, R.; Barraud, L.; Descoeudres, A.; et al. (2018)We applied hydrogen passivation, gettering and a combination of both to quasi-mono (qm) wafer material to enhance its bulk lifetime and prepared silicon heterojunction (SHJ) solar cells. We find that while our applied ... -
Simple processing of back-contacted silicon heterojunction solar cells using selective-area crystalline growth
Tomasi, A.; Paviet-Salomon, B.; Jeangros, Q.; Haschke, J.; Christmann, G.; Barraud, L.; et al. (2017)For crystalline-silicon solar cells, voltages close to the theoretical limit are nowadays readily achievable when using passivating contacts. Conversely, maximal current generation requires the integration of the electron ... -
The impact of silicon solar cell architecture and cell interconnection on energy yield in hot and sunny climates
Haschke, J.; Seif, J. P.; Riesen, Y.; Tomasi, A.; Cattin, J.; Tous, L.; et al. (2017)Extensive knowledge of the dependence of solar cell and module performance on temperature and irradiance is essential for their optimal application in the field. Here we study such dependencies in the most common high-efficiency ...
