SINOLTECH Powerful Foldable 215W Solar Panel for outdoor charging (FSC-HJT-215)
Introduction about Heterojunction Solar Cell The Most Potenttional & Competitive Solar Cell
>Japan Sanyo firstly disclosed a new solar cell structure named HIT (Heterojunction with Intrinsic Thinlayer) in 1990. p-n heterojunction is formed by passivating crystalline silicon cell surface with intrinsic a-Si:H and doped a-Si:H thin film bilayers. The structure avoids direct contact between metal electrode and silicon surface. It is a typical passivated contact solar cell with full area passivated.
> In 2014, Sanyo combined technical advantages of HIT and IBC (Interdigitated back contact) cell features, achieving solar cell efficiency up to 25.6%.
> In 2017, Kanaka improved the efficiency of HBC (Interdigitated heterojunction back contact) cell to 26.7%, which is now the highest efficiency record of crystalline cells.
> Silicon Heterojunction solar cell (short for "HIT" or "SHJ'') combines technical advantages of crystalline silicon cells and amorphous silicon cells. SHJ solar cell has low temperature coefficient excellent weak-light response, high bi-facial power gain and no LID. It can also made by supper-thinner silicon wafer. These features enable it the most potential and competitive crystalline solar cell.
