Solar cell module waterproof level

Are flexible organic solar cells waterproof?

Waterproof flexible organic solar cells without compromising mechanical flexibility and conformability remains challenging. Here, the authors demonstrate in-situ growth of hole-transporting layer to strengthen interfacial and thermodynamic adhesion for better waterproofness in 3 μm-thick devices.

Can ultraflexible solar cells withstand a machine-washing test?

Moreover, the ultraflexible devices withstand a machine-washing test with such a thin encapsulation layer, which has never been reported. Finally, we demonstrate the universality of the strategy for achieving waterproof solar cells. Water is a significant factor in the degradation of flexible electronics 1, 2.

How to fabricate a lightweight solar cell module?

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. As a reference sample, we fabricated solar cell modules with 3.2 mm-thick glass as the front-cover material. The sample structures are shown in Fig. 1.

What are the optical properties of single-cell modules?

Single-cell modules were visually inspected, and light I-V characteristics were measured at standard test conditions, STC (25 C and light intensity of 1,000 W/m2). The main optoelectronic properties monitored included the power at the PMAX, short-circuit current, VOC, and FF.

Are solar cells sustainable?

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.

What are the advantages of fabricated solar cells?

The fabricated modules have flexible properties. The lightweigh and flexible modules exhibit high reliability under both high temperature and high humidity conditions. Lightweight and flexible solar cell modules have great potential to be installed in locations with loading limitations and to expand the photovoltaics market.
