Perovskite-silicon tandem cells move from theory to reality with Hanwha Qcells' breakthrough
Solar energy is transforming the global energy landscape, driving the shift to renewables and accelerating decarbonization. Since the invention of the first practical silicon solar cell in 1954, solar technology has surged to a global capacity of 1.6 terawatts in 2023 — now supplying 5.5% of the world’s electricity. This remarkable growth underscores solar’s pivotal role in reshaping how we generate and consume energy. However, this progress has not come without challenges. Historically, the cos
