Direct Integration of Perovskite Solar Cells with Carbon Fiber Substrates
The integration of thin?film photovoltaics with structural components represents an attractive prospect for mobile power applications. In this work, the first example of perovskite solar cells deposited directly onto rigid carbon?fiber?reinforced polymer composite substrates is demonstrated, heralding a new class of photocurrent?generating materials with both high specific strength and power.Integrating photovoltaic devices onto the surface of carbon?fiber?reinforced polymer substrates should create materials with high mechanical strength that are also able to generate electrical power. Such devices are anticipated to find ready applications as structural, energy?harvesting systems in both the automotive and aeronautical sectors. Here, the fabrication of triple?cation perovskite n–i–p solar cells onto the surface of planarized carbon?fiber?reinforced polymer substrates is demonstrated, with devices utilizing a transparent top ITO contact. These devices also contain a “wrinkled” SiO2 interlayer placed between the device and substrate that alleviates thermally induced cracking of the bottom ITO layer. Devices are found to have a maximum stabilized power conversion efficiency of 14.5% and a specific power (power per weight) of 21.4 W g?1 (without encapsulation), making them highly suitable for mobile power applications.
