<p>A low concentration photovoltaic (LCPV) includes a solar panel (1) and a prism (2) whose principal section is in trapezoid shape, and a side of a upper bottom of the trapezoid cross section is connected to a phototropic face of the solar panel (1). Sides are respectively coupled with waists of the trapezoid facing towards a side of a lower bottom of the trapezoid, where the sides are reflecting faces. The energy conversion efficiency of LCPV is increased.</p>
