6 FAQs about [Single crystal silicon solar folding]

What is the device structure of a silicon solar cell?

The device structure of a silicon solar cell is based on the concept of a p-n junction, for which dopant atoms such as phosphorus and boron are introduced into intrinsic silicon for preparing n- or p-type silicon, respectively. A simplified schematic cross-section of a commercial mono-crystalline silicon solar cell is shown in Fig. 2.

How thin is a silicon solar cell?

Strobl et al. reported a 15.8% efficiency silicon solar cell with a thickness of 50 μm in the locally thinned regions and 130 μm for the frames 25. But other details of this structure are particularly underreported. There is also a “3-D” wafer technology developed by 1366 technology, Inc. around 2016.
