A method and apparatus for detecting crystal orientation of a silicon wafer is proposed. The detection method uses a camera shooting device to irradiate the silicon wafer in a rotation manner in different angular directions and obtains the corresponding reflection intensities, based on which a reflection curve is drawn for a grain of interest in a polar coordinate system; normal directions of three or more faces of a regular octahedron of a grain <111> are determined by identifying a pixel brightness extreme value in the reflection curve, and then all normal vectors of the regular octahedron are calculated, so that a crystal orientation of the grain of interest may be calculated. The camera shooting device has a light source and one or more camera shooting probes.

A hybrid all-back-contact (ABC) solar cell and method of fabricating the same. The method comprises: forming one or more patterned insulating passivation layers over at least a portion of an absorber of the solar cell; forming one or more hetero junction layers over at least a portion of the one or more patterned insulating passivation layers to provide one or more heterojunction point or line-like contacts between the one or more heterojunction layers and the absorber of the solar cell; forming one or more first metal regions over at least a portion of the one or more heterojunction layers; forming a doped region within the absorber of the solar cell; and forming one or more second metal regions over at least a portion of the doped region and contacting the doped region to provide one or more homojunction contacts.


In February 2014, Trina Solar and the Australian National University (ANU) jointly announced a world record aperture efficiency of 24.37% for a laboratory-scale 4cm2 IBC solar cell, fabricated on a Float Zone (FZ) n-type substrate and using photolithography patterning. In December 2014, Trina Solar announced a 22.94% total-area efficiency for an industrial version, large size (156x 156mm2, 6" substrate), IBC solar cell. In April 2016, Trina Solar announced an improved industrial low-cost IBC solar cell with a total-area efficiency of 23.5%. The new record of 24.13% total-area efficiency is just 0.24% absolute below the small-area laboratory cell record aperture-efficiency jointly established by the Company and ANU. Total-area efficiencies are always lower than aperture-efficiencies, due to efficiency losses related to the edges of the cells and electrical contact areas. "We are very delighted to announce the latest achievement from our research team at the SKL PVST. Over the last few years, our R&D team has managed to continuously improve the efficiency of our n-type IBC solar cells, pushing the limits and surpassing our previous records, and approaching very closely to the performance of our best small-area laboratory cell developed in collaboration with ANU three years ago." said Dr. Pierre Verlinden, Vice-President and Chief Scientist of Trina Solar. "IBC solar cells are one of the most efficient silicon solar cells available today and are particularly suitable for applications for which the requirement of a high power density is more important than LCOE (Levelized Cost of Electricity). Our IBC cell program has always focused on the development of large-area cells and low-cost industrial processes. We are very happy to announce today that our industrial large area IBC cell has reached almost the same level of performance as the small-area laboratory cell made three years ago with a photolithography process. In an innovation-driven PV industry, Trina Solar is always focused on developing leading-edge PV technologies and products with improved cell efficiency and reduced system cost. Our goal is to insist on technological innovation, and transform as quickly as possible the laboratory technology into commercial production."
