The newly developed all-peroxide series solar cells boast record high efficiency and voltage performance

Engineers have developed a modern solar cell with record voltage and efficiency for its kind. These all-peroxide series solar cells or solar pv cables use two layers of peroxides that can take advantage of different wavelengths of light, plus a special surface treatment that reduces energy waste. In photovoltaics, peroxidase is a particularly promising material …
