Thin-film solar cells, which use light-weight, highly-absorbing semiconductors, have the potential to dramatically lower manufacturing costs and accelerate deployment of solar energy via mechanically flexible architectures. Hybrid metal halide perovskites are the leading materials for this next-generation solar technology by virtue of their unprecedented optoelectronic properties and their synthesis from earth-abundant elements. The groundbreaking promise of perovskites is that they can be manufactured by scalable solution-coating methods, making them a potentially low-cost and high-performance energy technology with projected levelized cost of electricity (LCOE) below 3¢ / kWh.
This talk will discuss the current understanding of the optoelectronic properties of perovskites as well as how these properties inform the design of single-junction and tandem perovskite-silicon cell architectures. We will consider routes to upscaling perovskite module fabrication and look at challenges related to the fundamental thermomechanical reliability of these material systems.
