Flexible Solar Cell Substrate

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.

Flexible solar cell substrate.

Flexible solar cells plastic substrates light trapping embossing processes. The main difference between the rigid and flexible ultrathin organic solar cells can be seen in the substrates and passivation layers. In this section we focus on pi substrates for fabricating flexible displays. N i p processing starts with the n layer which is normally grown on a metallic back contact.

The technology for manufacturing solar cells on paper was developed by a group of. Efficient organometal trihalide perovskite planar heterojunction solar cells on flexible polymer substrates. Low sheet resistance that can maximize charge collection. Researchers at the indian institute of technology kanpur have developed 12 12 cm2 sub modules from organic solar pv cells on a paper substrate that could be used to power flexible electronic.

Google scholar das s. High optical transmittance that allows incoming solar radiation to reach and be absorbed by the photoactive layer. Except flexible displays such as amoleds pi substrates have also been applied to fabricate microelectrodes 160 solar cells 161 and sensors 162 etc. The performance of organic solar cells oscs has been steadily increasing surpassing 16 power conversion efficiency pce with advances in photoactive and charge transport materials.

Nonetheless the performance of flexible oscs still falls behind that of their rigid counterparts. 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. Further the high stability of cdte solar cells under proton and electron irradiation makes it suitable for space applications. To realize high efficiency flexible oscs substrates and transparent electrodes with the following characteristics are generally required.

High performance flexible perovskite solar cells by using a combination of ultrasonic spray coating and low thermal budget photonic curing. Further flexible materials are also used in the passivation layers. With this material they built tandem solar cells with 23 1 power conversion efficiency on a rigid substrate and 21 3 on flexible plastic. In the flexible organic solar cells flexible substrates polymers are used in most cases having thickness of 10 100 µm are used.
