A composite quasisolid electrolyte is prepared by adding a layered vermiculite (VMT) into the iodide/triiodide electrolyte including 4-tert-butylpyridine. which obviously improves the photovoltaic properties of quasisolid dye-sensitized solar cells (DSSCs). When adding 6 wt% VMT. the maximum photovoltaic conversion efficiency of 3. https://hollandscountryclothinges.shop/product-category/bobble-hats/
