Latest Patents

One of his latest patents is a method for fabricating a solar cell using inductively coupled plasma chemical vapor deposition (ICP-CVD). This method includes a first electrode, a P layer, an intrinsic layer, an N-type layer, and a second electrode. The process involves forming an intrinsic layer that consists of a hydrogenated amorphous silicon (Si) thin film by utilizing an ICP-CVD device with a mixed gas of hydrogen (H) and silane (SiH). In this mixed gas, silane gas is maintained in a ratio of 8 to 10 relative to the total gas mixture. Another notable patent also focuses on the fabrication of solar cells using ICP-CVD, where at least one of the second-type layer, intrinsic layer, and first-type layer is formed as a crystallized Si layer. This method employs a mixed gas with silane gas in a ratio of 0.016 to 0.02.
