Solar energy conversion holds the promise to power our societies sustainably. The ability to render solar cells based on perovskite absorbers ultrathin and highly conformable enables them to supply energy for a plethora of applications beyond large scale grid installations. Here, new metrices such as high specific power (W/g) and efficient conversion at low light intensities become paramount.
This talk introduces materials and fabrication methods for thin, light, flexible and stable quasi-2D perovskite solar cells with extreme mechanical properties that are unmatched in power produced per weight (up to 44 W/g) and show record breaking power conversion efficiency under indoor light illumination. Enabled through these photovoltaic devices, we demonstrate a set of applications that span from battery free medical wearables able to analyze sweat to ultra conformable X-Ray photodetectors, from solar powered aquatic millirobots to unmanned areal vehicles. On the fundamental side, we provide insights on interface and active layer engineering for enhanced environmental stability, enabling prolonged outdoor operation of sub-10-micrometer thin perovskite solar cells.
