PHOTOVOLTAIC PANEL AND ITS MANUFACTURING METHOD Russian patent published in 2021 - IPC H01L31/465 H01L31/18 H01L51/42 H01L51/46 

FIELD: coatings.

SUBSTANCE: photovoltaic panel (1) is proposed containing sequentially arranged first electrically conductive layer (10), photovoltaic layer (20) of perovskite photovoltaic material, second electrically conductive layer (30) and protective coating (40), which at least forms a barrier against moisture. First electrically conductive layer (10) is divided along first dividing lines (L11, L12) passing in the first direction (D1). Second electrically conductive layer (30) and photovoltaic layer (20) are divided along second dividing lines (L21, L22) passing in the first direction (D1) and along third dividing lines (L31, L32) passing in the second direction (D2) other than the first direction (D1). The first and the second dividing lines alternate with each other, and the first and the third dividing lines define area (50) that is filled with protective filling material forming the barrier against moisture, thereby defining photovoltaic cells sealed with protective coating material and protective filling material.

EFFECT: invention provides for the formation of the photovoltaic panel having a design that reduces the risk of lead or tin present in the photovoltaic layer entering the environment.
