192025 Affordable efficiency gains integrating perovskite-silicon tandems in next-generation photovoltaic systems Results in Engineering
Perovskite silicon tandem solar cells suggest a promising pathway to surpass the efficiency limits of traditional photovoltaics while remaining cost-competitive. In this study, a whole modeling process was endeavor to optimize perovskite-silicon tandem module production and deployment. Particle swarm optimization (PSO) yielded optimal parameters for manufacturing which are a coating speed of 10.00 m/min, an annealing temperature of 151.48°C, and a material thickness of 0.79 μm, resulting in an overall yield of 79.9 % and a defect rate of approximately 10.3 %. The manufactured cost was simulated at $0.387/W, significantly lower than the range of current industry benchmarks ($0.50-$1.00/W), prospects for a reduction to $0.25/W are promising within seven years. The simulated 25.4 % efficiency of modules provides ample room for improvement against our current best, of 34.6 % in laboratory conditions.
