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.A researcher in Germany has analyzed how top-cell transparency levels may affect bottom-ce…
In the world of solar energy, an improvement in efficiency of even just 0.1% is considered a remarkable achievement. Now imagine what it means to exceed by 1.15% what for decades has been considered an insurmountable theoretical limit. This is exactly what Longi has done with its new tandem silicon/perovskite photovoltaic cell. A conversion efficiency of 34.85%, certified by the prestigious American National Renewable Energy Laboratory, which re…
