Abstract

An integration of perovskite and cadmium telluride (CdTe) solar cells in a tandem configuration has the potential to yield efficient thin-film tandem solar cells. Owing to the promise of higher efficiency at low cost, the presented study aims to explore the potential for combining this commercially established CdTe photovoltaics (PV) with next-generation perovskite PV. Here, we developed four-terminal (4-T) CdTe/perovskite tandem solar cells, starting with 18.3% efficient near-infrared-transparent perovskite solar cells (NIR-TPSCs) with an average transmission (T_avg) of 24.76% in the 300–900 nm wavelength range. These were then integrated with 19.56% efficient opaque CdTe solar cells, achieving 23.42% efficiency in a 4-T tandem configuration. Additionally, using a refractive index matching liquid increases the overall power conversion efficiency (PCE) to 24.2%. This pioneering achievement marks the first instance of a 4-T CdTe/perovskite thin-film tandem solar cell exceeding a PCE of 24.2%, a significant 123.72% increase in overall PCE.

效率大于 24% 的 4-T 碲化镉/磷灰石薄膜串联太阳能电池

将透闪石和碲化镉（CdTe）太阳能电池集成在串联配置中，有可能产生高效的薄膜串联太阳能电池。由于有望以较低的成本实现更高的效率，本研究旨在探索将这种商业化的碲化镉光伏（PV）与下一代过氧化物光伏相结合的潜力。在此，我们开发了四端（4-T）碲化镉/包晶串联太阳能电池，首先是效率为 18.3% 的近红外透明包晶太阳能电池（NIR-TPSCs），其在 300-900 纳米波长范围内的平均透射率（Tavg）为 24.76%。然后，这些电池与效率为 19.56% 的不透明碲化镉太阳能电池集成，在 4-T 串联配置中实现了 23.42% 的效率。此外，使用折射率匹配液体还将整体功率转换效率（PCE）提高到 24.2%。这一开创性成就标志着 4-T 迭层碲化镉/过氧化物薄膜太阳能电池的 PCE 首次超过 24.2%，整体 PCE 大幅提高了 123.72%。

期刊介绍： ACS Energy Letters is a monthly journal that publishes papers reporting new scientific advances in energy research. The journal focuses on topics that are of interest to scientists working in the fundamental and applied sciences. Rapid publication is a central criterion for acceptance, and the journal is known for its quick publication times, with an average of 4-6 weeks from submission to web publication in As Soon As Publishable format. ACS Energy Letters is ranked as the number one journal in the Web of Science Electrochemistry category. It also ranks within the top 10 journals for Physical Chemistry, Energy & Fuels, and Nanoscience & Nanotechnology. The journal offers several types of articles, including Letters, Energy Express, Perspectives, Reviews, Editorials, Viewpoints and Energy Focus. Additionally, authors have the option to submit videos that summarize or support the information presented in a Perspective or Review article, which can be highlighted on the journal's website. ACS Energy Letters is abstracted and indexed in Chemical Abstracts Service/SciFinder, EBSCO-summon, PubMed, Web of Science, Scopus and Portico.
