Advances in Evaporated Solid-Phase-Crystallized Poly-Si Thin-Film Solar Cells on Glass (EVA)

Table 3

Suns-𝑉_oc results of an EVA sample measured before and after metallization of the BSF layer using line contacts in combination with an etching step that effectively reduces the shunting between emitter and BSF.
