SOLAR CELL

A solar cell includes a silicon substrate and an electrode formed on the silicon substrate. The silicon substrate has at least 5 raised portions having a cross-sectional height (h) of 50 nm or more per 5 μm length. The electrode is formed from a composition for solar cell electrodes including a cond...

Beschreibung
Zusammenfassung:	A solar cell includes a silicon substrate and an electrode formed on the silicon substrate. The silicon substrate has at least 5 raised portions having a cross-sectional height (h) of 50 nm or more per 5 μm length. The electrode is formed from a composition for solar cell electrodes including a conductive powder, an organic vehicle, and a glass frit having a glass transition temperature (Tg) of about 150° C. to about 450° C.
