This breakthrough in photovoltaic effects within two-dimensional (2D) semiconductor homobilayers will fundamentally reshape the design paradigm of next-generation optoelectronic devices. From a technical standpoint, it advances atomic-level doping control and nanoscale photovoltaic response measurement, opening new pathways for applications in photovoltaics and optical sensing. Upstream, material synthesis will see accelerated development of high-purity, defect-controlled 2D crystal growth, while downstream device fabrication faces heightened demands for doping precision and interface engineering. In terms of compliance, the technology’s commercialization may trigger stricter international supply chain reviews, particularly affecting semiconductor manufacturing hubs in Taiwan, China and Hong Kong, China, under potential export controls. Market players are likely to accelerate R&D investments in 2D material photonic chips, with traditional firms pursuing M&A strategies to gain technological parity. Over the next 12–24 months, this innovation is expected to drive growth in low-power, high-sensitivity photodetectors and flexible solar cells, establishing new market niches.
