Researchers in Switzerland have fabricated a perovskite-silicon tandem solar cells that utilizes a heterojunction cell as bottom device. The cell is said to circumvent the film formation issue ...
In HJT cells, an n-type crystalline silicon (c-Si) wafer is sandwiched between intrinsic amorphous silicon (i-a-Si:H) layers. The front is coated with n-type microcrystalline silicon (μc-Si:H), while ...
Maxwell Technologies has announced that its independently developed HJT solar cells have achieved a conversion efficiency of 26.92% on a full size 210 half-cut wafer (220.76 cm²). This milestone, ...
The cells used copper metallisation paste in place of silver. Image: Fraunhofer ISE. Scientists at the Fraunhofer Institute for Solar Energy Systems (ISE) have developed a new heterojunction ...
NexWafe’s EpiNex solar wafers achieved 24.4% efficiency on a commercial M6 heterojunction (HJT) cell line, for the first time delivering performance parity with conventional CZ wafers. Modules made ...
