NOVELTY - A photovoltaic solar panel comprises: (a) a first sheet (510) and a second sheet (550) adjacent to each other defining a space in between the two sheets; (b) energy conversion cells (525) arranged in groups in the space; and (c) an access matrix (540) in the space.    USE - The photovoltaic solar panel is useful for converting solar radiation incident to electricity.    ADVANTAGE - The photovoltaic solar panel includes photovoltaic cells and/or high voltage energy conversion cells. A high voltage energy conversion cell can generate power of high voltage which can be substantially proportional to the number of sub-cells it includes. Preferably, the energy conversion cell can generate a higher voltage than 0.6V.    DETAILED DESCRIPTION - A photovoltaic solar panel comprises: (a) a first sheet (510) and a second sheet (550) adjacent to each other defining a space in between the two sheets, where the first sheet is transparent to solar radiation incident on the panel; (b) energy conversion cells (525) arranged in groups in the space, where each group comprises an energy conversion cell, where the energy conversion cells are distributed across a substantially two-dimensional plane between and adjacent to the two sheets; and (c) an access matrix (540) in the space, where the matrix comprises electrical conductors that are electrically connected to the groups and that extend out of the space to provide electrical access to the groups from locations outside the panel, where the space is hermetically sealed to enclose the energy conversion cells. INDEPENDENT CLAIMS are included for:    (1) a photovoltaic power generation system comprising the photovoltaic solar panel; and    (2) a method of manufacturing the solar panel comprising: (a) providing the first sheet, the second sheet, energy conversion cells arranged in the groups, and the access matrix; (b) placing the first sheet; (c) placing the energy conversion cells distributed across the substantially two-dimensional plane over the first sheet; (d) placing the access matrix; (e) forming electrical connection between the access matrix and the energy conversion cells; (f) placing the second sheet over the access matrix; and (g) forming a hermetically sealed space comprising the first sheet, the second sheet, energy conversion cells, and the access matrix.
