Jinko's polycrystalline cells are so thin as to be almost impossible to keep from breaking, something on the range of 150um. I've got a few sitting here on my desk. Even an ultra-low pressure vacuum pick and place breaks them half of the time.
- philipkglass 8y agoThe mechanical fragility of thinner silicon has broadly stalled the progression toward even thinner wafers/cells. It's a pity since the optically/electronically optimum thickness would be thinner than is common now, and thinner wafers would yield more wafers per ingot. Do you know how Jinko is handling such thin wafers when they assemble their own modules? If they're making cells of such thinness they presumably have found a way to do it; nobody can afford to accidentally break half of their cells on the way to modules.
- lightedman 8y agoJinko rarely makes yheir own modules. They do very bad (almost to the point of fraud) subcontracting where they make you buy their materials, and any B-grade panel you make, you have to buy from Jinko. I honestly smell a scam in the way they operate, and I think the thinness of their janky poly cells is intentional.
