Accelerated Optimization of TiO2/Sb2Se3 Thin Film Solar Cells by High‐Throughput Combinatorial Approach

Accelerated Optimization of TiO2/Sb2Se3 Thin Film Solar Cells by High‐Throughput Combinatorial... Sb2Se3, a V2‐VI3 compound semiconductor, has attracted extensive research attention in photovoltaics due to its non‐toxicity, low cost and earth‐abundant constituents. Herein, a combinatorial approach to optimize the performance of TiO2/Sb2Se3 thin film photovoltaics is employed. By simultaneously conducting a series of experiments in parallel rather than one after another, combinatorial strategy increases experimental throughput and reduces personnel costs. Key parameters such as TiO2 thickness, post‐annealing temperature and Sb2Se3 thickness are identified as 65 nm, 450 °C and 850 nm through the combinatorial approach. Finally, in combination with (NH4)2S back surface cleaning, TiO2/Sb2Se3 solar cells with 5.6% efficiency and decent stability are obtained, showcasing the power of high‐throughput strategy for accelerating the optimization of Sb2Se3 photovoltaics. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advanced Energy Materials Wiley

Abstract

Sb2Se3, a V2‐VI3 compound semiconductor, has attracted extensive research attention in photovoltaics due to its non‐toxicity, low cost and earth‐abundant constituents. Herein, a combinatorial approach to optimize the performance of TiO2/Sb2Se3 thin film photovoltaics is employed. By simultaneously conducting a series of experiments in parallel rather than one after another, combinatorial strategy increases experimental throughput and reduces personnel costs. Key parameters such as TiO2 thickness, post‐annealing temperature and Sb2Se3 thickness are identified as 65 nm, 450 °C and 850 nm through the combinatorial approach. Finally, in combination with (NH4)2S back surface cleaning, TiO2/Sb2Se3 solar cells with 5.6% efficiency and decent stability are obtained, showcasing the power of high‐throughput strategy for accelerating the optimization of Sb2Se3 photovoltaics.
