[0158] Example 1 - Fabrication of perovskite solar cells for use in modules of the invention

[0159] A glass substrate (10x10 cm) coated with fluorine-doped tin oxide (FTO) was first etched with an automated fiber laser 2 , RSH=7Ω / Sq, product code: TCO22-7, Solaronix), and cleaned by sonication in 1% aqueous Hellmanex, acetone and isopropanol (15 minutes each). Then, by spray pyrolysis in a dilute solution of bis(acetylacetonate)titanium diisopropoxide (75% in isopropanol, Sigma-Aldrich) in absolute ethanol (1:80) using oxygen as a carrier gas Deposition of dense TiO on etched glass substrates 2 layer (30-40 nm), the substrate was placed on a hot plate set at 550°C. Areas of the substrate have been masked with glass strips to prevent coating in subsequent contact (silver) areas. After cooling to room temperature, silver paste (Sun Chemical CRSN2442) was screen printed and dried at 150° C. for 15 minutes to obtain silver contacts of anode and cathode. by dense TiO 2 On-la...

Abstract

The present invention relates to a double sided solar cell assembly, including at least one carbon-based perovskite solar cell unit which has been included in a sandwich structure together with a second solar cell unit which is a dye-sensitized photoelectrode.

Description

technical field [0001] The present invention relates to solar cells. [0002] In particular, the present invention relates to a solar cell module that can be used in various applications such as building-integrated photovoltaic applications, solar power parks with vertical vertical panels or inclined vertical panels, and for outdoor and indoor applications thereof consumer electronics. Background technique [0003] The current solar cell market is mainly composed of silicon-based cells. However, these are expensive alternatives, thus limiting their widespread use. In recent years, great progress has been made in the development of other battery types. [0004] A perovskite solar cell is a solar cell including a perovskite structure compound as a light harvesting active layer. The perovskite structure is usually composed of organic and inorganic components, the most common inorganic component being lead trihalide (PbX 3 ). [0005] The advantages of perovskite solar cel...
