High-quality super bright solar LED wall lamp solar knowledge: low conversion efficiency but lower cost silicon film

A non-silicon solar cell is not a pn junction but a pin-junction hydrogenated non-silicon (a-Si:H) thin film solar cell. The difference from a bulk silicon solar cell is that this type of solar cell does not utilize a minority carrier current. The spread of the child. Non-product silicon pn junctions do not have as good diode characteristics as crystalline silicon. This is mainly because the non-product silicon after doping, whether it is n-type or p-type, is of poor quality compared with undoped, the dangling bond catches the carrier, so that it cannot be separated, and the carrier is in the dangling bond. A rapid transition between them forms a short circuit. In order to prevent this from happening, it is necessary to form a certain structure, and insert a good performance i layer between the p layer and the n layer (i denotes Intrinsic, which is an abbreviation of intrinsic). When the i-layer produces a photo-generated carrier pair, the hole will be concentrated to the p-layer by the built-in electric field generated at the p-layer and the layer interface, and the electron will be concentrated to the n-layer by the built-in electric field generated at the interface of the retreat and the n-layer, so that the electron It will be effectively separated from the vacancies.
