Abstract

A photovoltaic panel (1) is provided, comprising in the order named, a first electrically conductive layer (10), a photovoltaic layer (20) of a perovskite photovoltaic material, a second electricallyconductive layer (30), and a protective coating (40) that at least forms a barrier against moisture. The first electrically conductive layer (10) is partitioned along first partitioning lines (L11, L12) extending in a first direction (D1). The second electrically conductive layer (30) and the photovoltaic layer (20) are partitioned along second partitioning lines (L21, L22) extending in the firstdirection (D1) and along third partitioning lines (L31, L32) extending in a second direction (D2) different from the first direction (D1l). The first and the second partitioning lines alternate each other and a space (50) is defined by the first and third partitioning lines that is filled with a protective filler material forming a barrier against moisture, therewith defining photovoltaic cells encapsulated by the protective material of the coating and the protective filler material.

Description

technical field [0001] The present invention relates to photovoltaic panels. [0002] The invention further relates to methods of manufacturing photovoltaic panels. Background technique [0003] Perovskites are promising materials for use as photovoltaic materials in the photovoltaic layers of photovoltaic panels. The name "perovskite" is used to refer to materials with the ABX3 crystal structure. The most commonly studied perovskite for use in photovoltaic cells is methylammonium lead trihalide (CH3NH3PbX3, where X is a halogen atom such as iodine, bromine, or chlorine), which has an optical bandgap between 1.5, depending on the halide content. and between 2.3eV. Another example is formamidinum lead trihalide (H2NCHNH2PbX3), which has a band gap between 1.5 and 2.2 eV. So far, no suitable substitute for the component lead has been found. Tin-based perovskite photovoltaic materials such as CH3NH3SnI3 have also been investigated. In the future, these tin-based perovskit...
