NOVELTY - Dye-sensitized solar cell (100) comprises anodic electrode (101) including an electrically conductive first substrate and a porous nanostructured active metal oxide layer (106) supported on it, where first substrate is positionable to receive incident light from a light source; cathodic counter-electrode (101, 103) including an electrically conductive second substrate spaced apart from the first substrate; and microlens array (120) disposed between the first substrate and the porous metal oxide layer, where microlens array comprises microlens components (121) operable to transmit light.    USE - Dye-sensitized solar cell used for operating and/or recharging various electronic devices used indoors under artificial lighting conditions.    ADVANTAGE - The microlens array improves solar conversion efficiency of the solar cell. It improves internal light transmission and distribution throughout the porous nanostructured semiconductor active metal oxide layer that provides a support lattice for the charge carrier such as photosensitive dye. This results in higher absorption rates of light by the dye and release of free electrons, increasing current density and power output per given surface area of the solar cell package. The microlens array is attributed with creating better dispersion of light through the nanocrystalline dye support structure, increasing contact of light with the photosensitive dye molecules resulting in higher electron transfer rates and power output from the solar cell. In contrast to conventional dye-sensitized solar cell, the dye-sensitized solar cell with microlens array allows the solar cells to extract more electrical power from both natural sunlight, and lower intensity indoor artificial lighting sources emitting a narrower spectrum of light that is convertible to electric power.
