Researchers have developed an industry-friendly process to fabricate crystalline silicon-based heterojunction (SHJ) thin-film solar cells. This innovation uses hot-wire chemical vapor deposition (HWCVD) to lower material and thermal costs by eliminating high-temperature processes and photolithography steps, making the technology scalable. These high-efficiency, low-cost solar cells are suitable for rooftop energy generation, agricultural applications, and transportation. The laboratory-tested single and double-sided SHJ cells demonstrated promising results under standard test conditions. This advancement addresses energy accessibility in rural areas, enhancing quality of life and sustainability.
