Abstract: Buildings consume approximately 40% of the world's energy demand, and the use of renewable energy sources is becoming increasingly urgent and important in the face of limited fossil fuel supply. Therefore, the integration of clean energy utilization and buildings is crucial.
Building-integrated photovoltaics (BIPVs) have many commercial uses, including BIPV foil products, BIPV tile products, BIPV component products, BIPV solar cell glass, and BAPV products. In all of these categories, various BIPV products are applied to various parts of building systems, including roofs, outdoor building partitions, semi-transparent curtain walls, windows, and shading systems. However, for photovoltaic curtain walls, the traditional black or dark blue colors of BIPVs are often inadequate to meet the color diversity requirements of architects for building materials.
Currently, many researchers have publicly disclosed several solar cell panel coloring techniques, but most of them are still in the laboratory stage. Among the relatively few colored solar cell panel products in the market, semi-transparent colored CdTe thin-film solar cell panels occupy a certain market share in the BIPV market due to their low cost and wide range of color options. Currently, related research has confirmed that the photovoltaic conversion efficiency of semi-transparent CdTe thin-film solar cell panels is around 12%. However, there is little evaluation of colored semi-transparent CdTe thin-film solar cell panels.
The purpose of this study is to evaluate the effect of blue and red backplanes on the maximum output power and photovoltaic conversion efficiency of CdTe thin-film solar cell panels in semi-transparent form. Results from simulation experiments and actual experiments show that the addition of colored backplanes to CdTe thin-film solar cell panels can have a certain impact on the temperature of the panels, thereby affecting the maximum output power. However, the impact is very small, with a reduction in maximum power of around 8% compared to CdTe thin-film solar cell panels without colored backplanes.
This also demonstrates that the use of colored backplanes as a way of coloring CdTe thin-film solar cell panels can maintain a certain output power while having a low cost and promising market prospects.
