Renewables still Australia’s lowest-cost option, says CSIRO
Firmed solar and wind deliver the cheapest pathway for new electricity supply across all scenarios in Australia, the Commonwealth Scientific and Industrial Research Organisation (CSIRO) says in its latest cost report.
The impact of transparent conductive electrodes on perovskite-silicon tandem solar cell performance
An Oxford researcher has found that transparent conducting electrodes can reduce perovskite–silicon tandem solar cell efficiency by over 2%, with losses linked to electrical resistance, optical effects, and geometric trade-offs. Using a unified optical–electrical model, the scientist showed how careful optimization of TCE stacks, coatings, and cell design is critical to closing the gap toward the 37%–38% efficiency frontier.
