Oxford PV collaboration simplifies perovskite tandem solar cell

Perovskite solar cell developer Oxford Photovoltaics (PV) has produced a 1 cm2 perovskite-silicon two-terminal tandem solar cell with a verified conversion efficiency of 25.2%, through an ongoing collaboration with Helmholtz-Zentrum Berlin (HZB) and the Photovoltaics and Optoelectronics Device Group at the University of Oxford, led by Professor Snaith.

Solliance and ECN touts 26.3% conversion efficiencies of tandem perovskite solar cell

Researchers at Solliance and ECN have fabricated a 6 inch industrially processed c-Si cell with a perovskite top layer that is mechanically stacked using ECN’s MWT-SHJ (metal-wrap-through silicon heterojunction) design that has achieved conversion efficiencies of 26.3%. The work was published during the Silicon PV/nPV conference, in Lausanne, Switzerland.

New perovskite aging measurements offered for standardization by EPFL

The École polytechnique fédérale de Lausanne (EPFL) is proposing the standardization of aging measurements of perovskite solar cells after developing a range of new methods that are claimed to best represent some of the unique characteristics of perovskite materials.

Progress and trends in CIGS and perovskite/CIGS PV

Thin-film solar cells based on chalcopyrite semiconductor Cu(In,Ga) (S,Se)2 compound (hereafter called CIGS or CIGSeS irrespective of the exact composition) have continuously drawn interest because of their progressively increasing high photovoltaic conversion efficiencies and the merits of long-term performance stability, high energy yield, low cost production potentials and other advantages for industrial manufacturing and application of solar.

JinkoSolar starts perovskite cell R&D collaboration

Leading ‘Silicon Module Super League’ (SMSL) member JinkoSolar has started a collaboration with Greatcell Solar, formerly Dyesol and the Nanyang Technology University (NTU) in Singapore on perovskite solar cells.
