Web1 nov. 2008 · Most research indicates that microwave ovens result in less extreme temperatures and in fact require less time for cooking than stove-top or oven methods. Boiling food is particularly deleterious. WebIn this case, the microwave radiation produced more efficient solar cells as compared to conventional annealing methods, but the reason is not clear. The current work is being undertaken partly to answer that question. More information: Binesh Puthen Veettil et al, Microwave annealing of silicon solar cells, Applied Physics Letters (2024). DOI:
