By slicing the material, 1 obtains both equally an increased-grade monocrystalline material along with a lower-grade polycrystalline output. The latter can be recycled to make only monocrystalline material. Any area passivation layer have to be eradicated just before implementing the electrodes – by way of example by laser ablation (see https://angelo57z22.ka-blogs.com/88981606/the-single-best-strategy-to-use-for-cell-solar-system-statement
