NOVELTY - Method for producing artificial leaves and needles in which petiole, stalk, including main leaves nerve and its rib segments are designed to hold and carry flexible thin-film representing a natural leaves shape and form, involves (a) preparing artificial petiole/stalk and leaves using variety of materials comprising synthetic materials including plastics (polythene, polystyrene), synthetic fibers (nylon, acrylics, and polyesters), synthetic resins, synthetic rubber, and recycled synthetic materials, and (b) affixing artificial leaves to form natural appearance of nature's existing flora.    USE - The method is useful for producing artificial leaves and needles used for capturing and converting environmental energies such as solar radiation, wind and sound energy into electrical energy.    ADVANTAGE - The method is inexpensive and simple. The obtained artificial leaves are strong hence cannot torn easily, and has different beautiful colors e.g. spots of yellow, red and white and several intermediate colors.    DETAILED DESCRIPTION - Method for producing artificial leaves and needles in which petiole, stalk, including main leaves nerve and its rib segments are designed to hold and carry flexible thin-film representing a natural leaves shape and form, involves (a) preparing artificial petiole/stalk and leaves using variety of materials comprising synthetic materials including plastics (polythene, polystyrene), synthetic fibers (nylon, acrylics, and polyesters), synthetic resins, synthetic rubber, and recycled synthetic materials, and (b) affixing artificial leaves to form natural appearance of nature's existing flora. The artificial petiole/stalk is prepared using waste biomass materials. The artificial leaves are prepared using bio-based material from renewable plant source. The artificial leaves are prepared in variety of shapes chosen from linear, elongate, obovate, egg shaped, narrow at base, ovate, pinnately lobed, palmately lobed, reniform, lanceolate, sagittate, arrow-shaped, falcate, flabellate, hastate, acuminate, aristate, cordate, cuneate, deltoid, obcordate, digitate, elliptic, obtuse, orbicular, rhomboid, rosette, acicular, spatulate, palmate, pedate, palmate, spear, bipinnate including pinnate, peltate, subulate, awl shape, perfoliate, trifoliate/ternate, odd pinnate, tripinnate including bipinnate, pinnate, truncate, pinnatisect, unifoliate, and whorled ring. The artificial petiole/stalk has a unit to receive and connect with a piezoelectric connecting element, or as a separate element being an integral part of the leaves. The artificial leaves surface areas are designed to absorb indirect or secondary solar radiation and to mimic leaves solar radiation reflection and solar radiation refraction. The artificial leaves surface area is in the form of canescent (covered with fine whitish hairs or down), echinate (bearing or covered with spines or bristles, and prickly), farinaceous (textures that are rough to the touch or substances consisting of relatively large particles), floccose (covered with tufts of soft hair), glandular (relatinq to affecting or resembling a gland), hirsute (covered with stiff or coarse hairs), hirtellous (pubescent with minute and somewhat rigid hairs), hispid (covered with stiff or rough hairs, and bristly), lanate (having or consisting of woolly hairs), lepidote (covered with small, and scurfy scales), muricate (shaped like a murex, and pointed), pannate (fine hairs), papillate (minute projection on the surface of a stigma, petal, or leaves), pilose (covered with fine soft hair), puberulent (covered with minute hairs or very fine down, finely pubescent), pulverulent (made of, covered with, or crumbling to fine powder or dust), resinous (any of numerous clear to translucent yellow or brown, solid or semisolid, viscous substances of plant origin), scabrous (having or covered with scales or small projections and rough to the touch), scurfy (a loose scaly crust coating a surface, especially of a plant), sericeous (covered with soft silky hairs), setose (having or covered with protective barbs or quills or spines or thorns or setae), stellate (arranged or shaped like a star, radiating from a center), strigose (having stiff, straight, closely appressed hair), tomentose (covered with short, dense, matted hairs), tuberculate (covered with tubercles), uncinate (bent at the end like a hook), velutinous (covered with dense, soft, silky hairs), and villous (covered with soft, shaggy unmatted hairs). INDEPENDENT CLAIMS are included for the following:    (1) use of synthetic or organic flexible substrate provided with a thin-film photovoltaic cell and thermovoltaic cell on either side of the flexible thin-film substrate;    (2) artificial leaves for converting solar radiation into usable electrical energy;    (3) separately designed element; and    (4) separate piezoelectric connective element.
