Perovskite Photovoltaics: The Path to a Printable Terawatt-Scale Technology

Abundant, low-cost, reliable, and clean energy is critical not just to maintain but also to improve the living conditions across the globe. Because of the world's unrelenting population and GDP growth that is only slightly offset by reductions in energy intensity per $ of GDP, it has been estimated that by 2050 the world will consume an average of 30 Terawatts (TW) of total (i.e., not just electricity) energy, of which, assuming no current generation capacity retires, at least between 10-15 TW will be completely new capacity. Addressing this 'Terawatt challenge', a term originally coined by Richard Smalley in 2004, in a nonpolluting and sustainable way is integral to addressing socioeconomic needs in both industrial and rapidly developing countries worldwide. In conjunction with ongoing electrification of the energy system, the vastness of the available solar resource will provide a solution to the world's energy needs if we can develop sufficiently low-cost, high-performance, and massively scalable photovoltaic (PV) technology.

Solvent-Assisted Linker Exchange: An Alternative to the De Novo Synthesis of Unattainable Metal-Organic Frameworks

Metal-organic frameworks (MOFs) have gained considerable attention as hybrid materials—in part because of a multitude of potential useful applications, ranging from gas separation to catalysis and light harvesting. Unfortunately, de novo synthesis of MOFs with desirable function–property combinations is not always reliable and may suffer from vagaries such as formation of undesirable topologies, low solubility of precursors, and loss of functionality of the sensitive network components. The recently discovered synthetic approach coined solvent-assisted linker exchange (SALE) constitutes a simple to implement strategy for circumventing these setbacks; its use has already led to the generation of a variety of MOF materials previously unobtainable by direct synthesis methods. This Review provides a perspective of the achievements in MOF research that have been made possible with SALE and examines the studies that have facilitated the understanding and broadened the scope of use of this invaluable synthetic tool.
