The present invention relates to a chemical toner composition and a method for preparing the same. The chemical toner composition includes: a resin emulsion; a pigment dispersion; a wax dispersion; and a dispersible polymer coagulant, wherein the dispersible polymer coagulant is a copolymer comprising unsaturated ester monomers and amino-containing monomers. Accordingly, the present invention uses a novel dispersible polymer coagulant to prepare uniform toner particles with excellent roundness and improved flowability and to reduce moisture absorption.

A retractable lens assembly with a variable-volume lens is provided. The retractable lens assembly includes an optical lens, a variable-volume lens, a fluid pump, a communication tube, and a storage tank. The variable-volume lens includes a lens film, an accommodation space wrapped by the lens film, and a transparent fluid within the accommodation space. Therefore, when the transparent fluid is pumped from the accommodation space to the storage tank by the fluid pump, the variable-volume lens is folded because of atmospheric pressure, such that the overall thickness and volume are reduced. When the variable-volume lens is folded, the thickness of the retractable lens assembly is as small as possible. When the variable-volume lens is stretched out because of being filled with the transparent fluid, the variable-volume lens and the optical lens are of a coaxial configuration, forming a photographic optical system.

This invention discloses a novel method for fabricating solar cells. Using the existing screen-printing, masking or photolithography techniques, a P-type or N-type diffusion source is coated on the sites of an N-type or P-type silicon wafer desired for forming electrodes. Then, a low dose P-type or N-type diffusion source is in situ diffused into the N-type or P-type silicon wafer together with the P-type or N-type diffusion source coated on the N-type or P-type silicon wafer in the furnace. Thereafter, a P−/P+ or N−/N+ diffusion region is formed within the N-type or P-type silicon wafer. Finally, electrodes aligned to the P+ or N+ diffusion region are formed by means of screen-printing. Then, a solar cell with high photocurrent and low series resistance can be obtained.
