A new approach to produce low-cost silicon solar cell sheets. Currently more than 80% of the commercial solar cell production requires cutting large silicon crystals, which is time consuming and generally results in the loss, as ‘saw-dust’, of around 50% of the expensive cast silicon material.

Solar Silicon Wafers as-cut wafers high-quality-low-price

Silicon heterojunction solar cells (SHJ), which consist of N-silicon wafers (Cz), have aroused growing industrial interest. The low efficiencies can be achieved by using low-cost, high-efficiency silicon cells, and the cheap silicon can also be used to form SH J cells. The work uses a Monte Carlo simulation approach that allows us to take into ...
