Abstract: Methods, systems, and devices are disclosed for implementing and fabricating electrochemical solar cells including dye-sensitized and perovskite-sensitized solar cells. In one aspect, a dye-sensitized solar cell device includes a cathode including a metal mesh structure that is optically transmissive and electrically conductive, an anode including a metal base layer that is optically opaque and electrically conductive, one or more layers of a semiconductive oxide coupled to the anode, the one or more layers of the semiconductive oxide including nanostructures having a photosensitive dye material coating, in which the anode generates photoelectric energy based on absorption of light by the photosensitive dye material, and an electrolyte of a substantially transparent substance and formed between the cathode and the one or more layers of a semiconductive oxide.

Abstract: A wrap-around jumper dress capable of neatly fitting a variety of shapes and sizes of female figures. The garment is formed of a separate bib and a separate wrap-around skirt. The lower edge of the bib is concave and joined to the concave edge of the front central portion of the skirt. A sash is attached to the opposite upper corners of the skirt and a sash-receiving opening is formed in one of the upper corners of the front central portion of the skirt. Preferably, the skirt is formed in three sections, a front central section and right and left hand sections. The invention is deemed an improvement over the garments shown in patents Nos. 1,209,018; 1,497,232; 2,136,983 and 2,507,602.
