摘要：
A solar cell having buried contacts is provided. Curved trenches are formed on a surface of a Si substrate to form the buried contacts. The curved trenches have deep depths with wafer break prevented. The buried contacts have good efficiency on collecting electrons obtained from conversion by the longer wavelength light. The present invention is fit for mass production with a high yield, a simple fabrication procedure, a low cost and a good performance.
