Long-standing limitation in thin-film solar cells resolved with nanometric germanium oxide layer

Long-standing limitation in thin-film solar cells resolved with nanometric germanium oxide layer

As the world urgently seeks clean energy solutions, solar power stands out for its abundance and scalability compared to other renewable energy sources. In recent years, researchers have turned to thin-film solar cell technologies as alternatives to traditional crystalline silicon solar cells, owing to their lower manufacturing costs, better reproducibility, and applicability in flexible electronics.
