Customer ServiceThe development of lightweight and flexible modules, both for thin-film solar cells and c-Si solar cells, along with the utilization of stacked solar cell modules, will be an important future issue in the solar cell industry.
The thin film solar cells with an average conversion efficiency of 30% (AM0) were connected together in series to increase the module’s voltage up to 500 V. The flexible thin film module was thermal laminated using a POSS modified transparent polyimide film.
The strings at the busbar were connected by machine soldering, and the strings of the four-cell modules were connected in series by hand soldering. To fabricate a lightweight solar cell module, we used a 0.025 mm-thick PET film sheet as both a front-cover and a backsheet. The solar cells were encapsulated with EVA.
Solar cells are one of the most sustainable forms of renewable energy. Crystalline silicon (c-Si) solar cell modules hold greater than 90% of the solar cell module market share. Despite recent developments in other types of semiconductor cells , c-Si solar cell modules are predicted to remain a major type of solar cell module in the future.
The thin film solar cells with an average conversion efficiency of 30% (AM0) were connected together in series to increase the module’s voltage up to 500 V. Increasing module’s voltage allows to reducing the resistive losses during long distance current transportation and is enable inverter simplification leading to more efficient.
