3D-printed anti-reflective cover based on aluminium oxide increases PV cell efficiency by 25%
An international team of scientists have combined cyclic-olefin copolymers with a powder of aluminum oxide to create a filament that can be used by a 3D printer to create anti-reflective covers for PV modules. The proposed innovation can reportedly improve PV cell efficiency by over 25%.
KAUST, Helmholtz-Zentrum Berlin present 31.2%-efficient blade-coated perovskite-silicon tandem solar cell
The perovskite-silicon tandem device has a two terminal configuration and a 2D perovskite layers at the bottom interface. It was able to retain around 80% of its initial efficiency for 1,700 h.
Multiple designs of photovoltaic-thermal collectors
Scientists have modeled eight different kinds of PVT systems, some with a glass covers and some without. They found the worst efficiency was achieved in uncovered systems with parallel round tubes.
