NOVELTY - Concentrated solar power (CSP) device comprises flat reflective panels attached or positioned along latitudinal sides of rectangular photovoltaic cell (1) or cell combination (thus orienting to sun's diurnal east-west motion) and/or at longitudinal ends (thus orienting to seasonal changes in sun's path), to redirect by angulature rays falling adjacently outside its periphery upon cell, where cell or cells and device are fixed, tiltable, or heliostatic, hence extending daily input to cell or cells at different times along with amplifying cell's or cell's net daily power output.    USE - The concentrated solar power device is useful for nocturnal usage for office, store, and household lighting at both night and day.    ADVANTAGE - The concentrated solar power device: utilizes flat or curved reflectors and/or lenses which increase the power from full, diffracted and low-angle sunlight and optimizes photovoltaic energy in situ without expensive heliostat systems; and has increased cell receptivity.    DETAILED DESCRIPTION - Concentrated solar power (CSP) device comprises flat reflective panels attached or positioned along the latitudinal sides of a rectangular photovoltaic cell (1) or cell combination (thus orienting to the sun's diurnal east-west motion) and/or at the longitudinal ends (thus orienting to seasonal changes in the sun's path), to redirect by appropriate angulature rays falling adjacently outside its periphery upon the cell or cell combination, where the cell or cells and device are fixed, tiltable, or heliostatic, hence extending daily input to the cell or cells at different times along with amplifying the cell's or cell's net daily power output.
