A solar cell pre-laminate assembly comprising (i) a solar cell component comprising one or a plurality of solar cells and having a light-receiving side and a back side, and (ii) stiff poly(vinyl butyral) sheet as an encapsulant layer, wherein the stiff poly(vinyl butyral) sheet is positioned next to the light-receiving or the back side of the solar cell component and comprises a poly(vinyl butyral) composition containing about 10 to about 23 wt % of a plasticizer based on the total weight of the composition. A process of preparing solar cell assembly comprising (i) providing a solar cell component and a stiff poly(vinyl butyral) sheet comprising a poly(vinyl butyral) composition containing about 10 to about 23 wt % of a plasticizer based on the total weight of the poly(vinyl butyral) composition, and (ii) encapsulating the solar cell component in a polymer matrix comprising the poly(vinyl butyral) composition.
