Thin film solar cell module and method of manufacturing the same

A thin film solar cell module comprising: a first substrate; a first electrode layer over the first substrate; a light absorption layer over the first electrode layer; a second electrode layer over the light absorption layer; and a second substrate over the second electrode layer; wherein an edge region is located between the first and second substrates and an encapsulation layer is provided between the said first and second substrates in at least the said edge region; characterised in that the thin film solar cell module further comprises an electrically conductive member situated in the said edge region, the said electrically conductive member forming an edge seal extending at least a part of the way between the first and second substrates.
