Abstract: A flexible and mechanically-resilient Photovoltaic (PV) cell is formed of a single semiconductor wafer. It includes non-transcending craters or bling gaps, that penetrate upwardly from a dark-side surface towards a sunny-side surface but do not reach the sunny-side surface. The craters segment the wafer into miniature sub-regions, and provide mechanical resilience and mechanical shock absorption. A set of conducting wires are located on each side of the PV cell; one set collects the negative electric charge, and the other set collects the positive electric charge. The conducting wires are embedded in an adhesive transparent flexible plastic foil. Optionally, a bi-facial PV cell is similarly provided, as well as methods and systems for producing such PV cells.

Abstract: Engineered stone, and methods of manufacturing same. An engineered stone comprises: a surface of the engineered stone, wherein the surface comprises one or more pores; and a sealant mixture including a sealant material and a functional component, wherein the functional component modifies one or more properties of said engineered stone.
