NOVELTY - An organic solar photovoltaic cell (1) is manufactured by obtaining indium-oxide-patterned substrate, forming sol-gel zinc oxide precursor solution, spraying sol-gel zinc oxide precursor solution on patterned indium oxide substrate (5) to form zinc oxide layer, annealing zinc oxide layer, spraying active layer (15) containing bulk heterojunction composition on zinc oxide layer, spraying anodic layer containing poly(3,4)-ethylenedioxythiophene:poly-styrenesulfonate mixed with 5 vol.% of dimethylsulfoxide on active layer to form solar photovoltaic cell array, and placing cell into high vacuum.    USE - Manufacture of organic solar photovoltaic cell (claimed).    ADVANTAGE - Fabrication process is shortened which reduces manufacturing cost, power conversion efficiency and device characteristics, such as shunt resistance and fill factor, are improved, and human factors e.g. manual erasing of active layer to make series connections by providing a complete solution processable manufacturing process are eliminated.
