Novel IBC solar cell architecture based on crystal photonics shows efficiency potential of 29.1%
Scientists in Germany designed a poly-Si on oxide (POLO) interdigitated back-contact (IBC) solar cell integrating photon crystals and found this architecture has the potential to reach a power conversion efficiency of over 28%, which would be 1% higher than the current practical limit set by the scientific community. They also found that by improving passivation, the efficiency may be raised up to 29.1%.
Flexible PV panels based on hyperconnected back-contact solar cells
US start-up mPower Technology is scaling up its flexible crystalline silicon solar module technology for spatial and terrestrial applications. The back-contact solar panels consist of micro-singulated silicon dies that are “hyper-interconnected” in series or in parallel. The devices have efficiency ranging from 22 to 23% depending on the size or applications.
