NOVELTY - The photovoltaic cell comprises a photovoltaic layer (302) with a light receiving top node (302a) and a bottom node, a first conductive layer (303) electrically coupled to the bottom node of the photovoltaic layer so the first conductive layer does not block light from the photovoltaic layer, a second conductive layer (304) adjacent to and electrically insulated from the first conductive layer so the second conductive layer does not block light from the photovoltaic layer, and a through silicon via (306, 308) electrically coupled to the light receiving top node of the photovoltaic layer.    USE - Used as a photovoltaic cell such as solar cell.    ADVANTAGE - The photovoltaic cell has increased efficiency and enhanced internal resistance, and reduces the obstruction of light from the metallic traces using through silicon vias.    DETAILED DESCRIPTION - The photovoltaic cell comprises a photovoltaic layer (302) with a light receiving top node (302a) and a bottom node, a first conductive layer (303) electrically coupled to the bottom node of the photovoltaic layer so the first conductive layer does not block light from the photovoltaic layer, a second conductive layer (304) adjacent to and electrically insulated from the first conductive layer so the second conductive layer does not block light from the photovoltaic layer, a through silicon via (306, 308) electrically coupled to the light receiving top node of the photovoltaic layer and the second conductive layer, a light refracting layer (314) that deflects the light into the photovoltaic layer and is adjacent to the light receiving top node of the photovoltaic layer, and a load (318) that promotes current flow between the first conductive layer and the second conductive layer. The through silicon via is electrically insulated from the photovoltaic layer and the first conductive layer. The light refracting layer is an electrode layer that is electrically coupled to the photovoltaic layer and the through silicon via. The through silicon via extends from the first node of the photovoltaic layer through the photovoltaic layer and the first conductive layer to the second conductive layer, and provides a conductive path from the first node to the second conductive layer. The through silicon via comprises a first end that is exposed at the light receiving top node and electrically coupled to the electrode layer, and is spaced relative to another through silicon via in an electrically conductive relationship so to form a through silicon via array. The electrode layer absorbs light reflected from the through silicon via. INDEPENDENT CLAIMS are included for:    (1) an apparatus for reducing obstruction of light to a photovoltaic cell; and    (2) a method of reducing blocked light to a photovoltaic cell.
