Flexible Solar Cell Substrate

Efficient organometal trihalide perovskite planar heterojunction solar cells on flexible polymer substrates.

Flexible solar cell substrate.

In 2011 researchers from mit created a flexible solar cell by inkjet printing on normal paper. Further flexible materials are also used in the passivation layers. Thin film silicon solar cells are classified into p i n and n i p configurations which refer to their deposition sequence. Flexible solar cells plastic substrates light trapping embossing processes.

Perovskite solar cell pscs have achieved an amazing power conversion efficiency pce of 24 2 which exceeds the pces of inorganic solar cells. This enabled us to fabricate a crack free perovskite film on an ultra thin substrate 2 5 μm and to demonstrate ultra flexible solar cells with high efficiency 17 03 with unprecedented flexibility sustained after 10 000 cycles of bending at a 0 5 mm radius. Flexible solar cell research is a research level technology an example of which was created at the massachusetts institute of technology in which solar cells are manufactured by depositing photovoltaic material on flexible substrates such as ordinary paper using chemical vapor deposition technology. The main difference between the rigid and flexible ultrathin organic solar cells can be seen in the substrates and passivation layers.

The biggest trend in recent history when it comes to printed electronics is the widespread use of them in solar cells. Except flexible displays such as amoleds pi substrates have also been applied to fabricate microelectrodes 160 solar cells 161 and sensors 162 etc. Google scholar das s. The technology for manufacturing solar cells on paper was developed by a group of.

The cost effective material mechanical durability and the potential for a solution based roll to roll process make the psc suitable for realizing flexible solar cell on a plastic substrate. In 2018 researchers at rice university have developed organic solar cells which can be painted or printed onto surfaces. In this section we focus on pi substrates for fabricating flexible displays. Efficient and ultra lightweight inverted pbs qds solar cell is fabricated on all cvd growth of parylene graphene ocvd pedot substrate and an efficiency of 7 1 and a power per weight of 12 3 w g 1 ar.

Since the solar cell can be as thin as 5 μm and the flexible substrate is 5 10 μm thick weight savings compared to glass substrates are significant. In the flexible organic solar cells flexible substrates polymers are used in most cases having thickness of 10 100 µm are used.
