This report describes the development of perovskite-on-silicon tandem solar cells. Tandem solar cell technology has the potential to achieve an efficiency that improves upon today’s solar panels by up to 50 percent relative, thereby reducing the cost of solar installations and lowering the cost of solar for California ratepayers. Advancements were also made in devel-oping a mechanically compliant conductive adhesive for silver-free shingling of cells into robust modules. The cell and architecture advances hold promise to enhance energy yields of solar installations when the sun is not shining directly overhead, raise overall system efficiency, and reduce the cost and resource-intensity of solar. This technology contributes significantly to California’s mandated energy goals to reduce greenhouse gas emissions, meet renewable energy targets, and promote a cleaner environment.
