Are flexible photovoltaics (PVs) beyond Silicon possible?

Recent advancements for flexible photovoltaics (PVs) beyond silicon are discussed. Flexible PV technologies (materials to module fabrication) are reviewed. The study approaches the technology pathways to flexible PVs beyond Si. For the previous few decades, the photovoltaic (PV) market was dominated by silicon-based solar cells.

Which substrate material is used for crystalline silicon (c-Si) photovoltaic modules?

Currently, rigid substrate materials, most commonly glass, are employed for crystalline silicon (c-Si), including both the monocrystalline silicon (mono-Si) and polycrystalline silicon (poly-Si) photovoltaic modules.

Can glass be used as a flexible PV substrate?

However, even with high flexibility, the intrinsic opaque appearance makes it much less interesting for being utilized as flexible PV substrates. Glass has long been the common choice for quite many building envelope applications including atrium roofs and skylights where materials with lightweight, high strength, and low cost are essential.

Do flexible PV cells with a silicon substrate work better?

Flexible PV cells with a silicon substrate can work much better than other similar flexible materials [9, 10]. In this study we consider a basic mechanism for the conversion from Sol. Energy to power generation and the progress in PV development by using silicon materials.

Can plastic substrates be used for flexible PV devices?

Among them, plastic (polymer) substrates have been widely used for conventional flexible PV devices. Plastic substrates have many advantages, such as good optical transmittance in the visible range, low cost, lightweight, and a simple design. Recently, many studies have focused on the use of plastic materials for flexible circuits [19, 20].

Can metal sheets be used as flexible PV substrates?

With appropriate thickness, metal sheets could be suitable for layer deposition, and enough flexible for flexible PV needs. However, even with high flexibility, the intrinsic opaque appearance makes it much less interesting for being utilized as flexible PV substrates.
