A kind of preventing hot spot photovoltaic module comprises the cell piece array, connect conductive strips and the conductive strips that conflux, and described cell piece array is divided into some Battery pack strings, and described battery strings is formed by series connection conductive strips some cell pieces of connecting; The described conductive strips that conflux described battery strings in parallel.
Further, described series connection conductive strips form battery strings along the some cell pieces of vertical or horizontal series connection of described cell piece array; Described conflux conductive strips then along with the vertical direction batteries in parallel connection string of the conductive strips of connecting.
Further, the described conductive strips that conflux adjacent between 1 to 5 cell piece in interval.
Further, described series connection conductive strips and the conductive strips that conflux are plain conductor.
Further, described cell piece is polycrystalline silicon battery plate or monocrystalline silicon battery sheet.
Compared with prior art, the advantage of technical solutions of the utility model is:
By series connection conductive strips and the conductive strips that conflux, the cell piece array is divided into some zones, be blocked in certain zone and when becoming a load, this road electric current can be by the conductive strips shunting of confluxing, get around this zone, avoid producing the hot spot phenomenon, prevent that cell piece from damaging.Preventing hot spot photovoltaic module described in the utility model is without bypass diode, and simple in structure, series resistance is little, has not only reduced cost, and has improved the overall power of photovoltaic module.
