Top cell transparency remains critical challenge for tandem solar cells
New research from Germany has shown how improving top-cell transparency and performance remains key to the commercialization of tandem perovskite-silicon solar cells, as well as for all other types of tandem devices. The analysis demonstrated, in particular, that the top cell must achieve higher single-cell efficiency to compensate for reduced transparency.
Balcony solar gains US foothold with plug-and-play systems
Bright Saver, a San Francisco-based nonprofit, aims to bring the European balcony solar trend to US homes with low-cost, plug-in systems that require no interconnection approvals or permits in some jurisdictions.
Preventing soiling with surface textured photovoltaic dummies
Scientists in South Africa have used computational fluid dynamics to investigate whether a dummy panel, placed in front of a working PV panel, can mitigate soiling. They have tested this setup with various inclination angles, heights, and distances and have found that the dummies accumulated up to 58% more dust than the PV panels.
Chinese PV Industry Brief: Polysilicon, solar module prices continue to slide
