Influence of random pyramid surface texture on silver screen …
Most industrial monocrystalline silicon wafer (mono-Si) solar cells are metallised by screen using thick film pastes. Silver (Ag) screen-printed pastes are generally used to form electrodes to phosphorus (P)-doped n + Si. Traditionally Ag crystallites grown into the n + Si during the firing step have been identified to be primarily responsible for contact formation [1].
