While perovskites offer high optical absorption, a significant portion of light can still be transmitted through the thin photoactive layer without being fully utilized. To address this, we propose the development of back electrodes and reflective structures based on low-cost, durable metals. This approach aims to trap more light within the perovskite layer, either by reflecting transmitted photons back for a second pass or by plasmonic enhancement. Given the cost-effective nature of perovskite fabrication, it is crucial that these back-contact solutions also leverage inexpensive and robust metals (such as Al, Cu, or Ag alloys) to maintain the overall economic advantage over silicon solar cells and facilitate future commercialization. Research in this area is essential to push the power conversion efficiency of perovskite photovoltaics closer to their theoretical limits without compromising their low-cost potential.
