State-of-the-art metal halide perovskite-based photovoltaics often employ organic ammonium salts, AX, as a surface passivator, where A is a large organic cation and X is a halide. ONE Lab is a core contributor to the MIT GridEdge Solar research program, working toward scalable design and manufacturing of lightweight, flexible solar cells. Our work in ONE Lab focuses on the basic photophysics and chemistry of emerging PV materials, from QDs to molecular organics to perovskites, as well as development of scalable device architectures and large-area processing methods for emerging thin-film PV technologies. They can also satisfy global energy needs without major constraints on material abundance, material production, or land use. In the long term these technologies could reach PV module and system cost floors unachievable with conventional silicon. Flexible, monolithically integrated modules are inexpensive to manufacture and durable when deployed, with no wafers to break or solder joints to fail. Low-temperature processing allows lightweight substrates to be used, leading to high power-to-weight ratios and flexible cells that are easy to transport, store, and install. Unlike conventional technologies, organic solar cells can be made visibly transparent for ubiquitous deployment. These materials open the door to new formats for deploying solar power. Emerging nanomaterials such as perovskites, organics, and QDs are structurally complex but simple to process. While PV module costs continue to decline rapidly, however, further system-level cost reductions will likely require lightweight and flexible module designs that are inaccessible with today's c-Si technologies.Įmerging thin-film PV technologies provide new functionality today and could reshape the solar landscape tomorrow. Global PV deployment is dominated by crystalline silicon (c-Si) wafer-based technologies, which benefit from high power conversion efficiencies, abundant materials, and proven manufacturability. Solar photovoltaics (PV) are the fastest-growing energy technology in the world and a leading candidate for terawatt-scale, carbon-free electricity generation by mid-century.
