EXTENSION OF R & D

FeS on stainless steel substrate: Flexible solid-state supercapacitor:

The symmetric FSS-SCs device was fabricated using FeS thin film as active electrode with

PVA-LiClO4 gel electrolyte, which is schematically presented in Fig. (a). Two FeS electrodes

Fig. (b) were sandwiched by using PVA-LiClO4 polymer gel electrolyte in between. Fig. (b

to d) shows the steps involved in fabricating FSS-SCs device. The voltage window of 2 V

was successfully achieved which is auspicious for increasing energy density and

manufacturing device for practical application.

To validate the practical application of solid-state device, the formed device was charged at

2.5 V constant potential and discharged through one red colour LED. The discharged device

can glow a LED upto 30 s which is shown in figure.

DAE-BRNS Project entitled “Chemical Synthesis of Quantum Dots and their sensitization

for the applications in Solar Cells”

Development of device

grade solar cell is based on the

basic principle of dye sensitized

solar cell in which quantum dots

(q-dots) of inorganic

semiconducting materials will be

used instead of dye molecules.

These q-dots belong to group V-

VI and II-VI family will be

sandwiched between a high surface area n-type wide band gap semiconducting material

(TiO2) and p-type charge transport material (organic/inorganic). These Q-dots will be

deposited by using simple and l ow cost soft chemical and/or electrochemical routes. These

dots have chosen since it is easy to tune their band gap in the visible region of the solar

spectrum with respect to their sizes. Initially, device with liquid electrolyte will be checked

instead of p-type layer for better pores filling. After getting proper efficiency, liquid

electrolyte will be replaced with p-type material in the final stage to have complete solid-state

device.

2) DST Project entitled “Colorful, device grade dye sensitized solar cell based on

nanoporous ZnO films with targeted efficiency of 4-5%”.

The new, innovative idea is built on the development of low cost thin film solar cell based on

dye sensitized solar cell.

The following figure summarizes the latest result achieved

In this project, we have succeeded to make a active and working colorful devices based on

chemically synthesized ZnO for the dye sensitized solar cells with the structure

TCO/ZnO/dye/electrolyte/contact

3) UGC Project entitled “Hetero-junction based LPG sensor”.

Liquefied petroleum gas (LPG) is one of the most useful fuels for automobiles, vehicles,

industry and most importantly for daily household purposes. The increasing usage of this fuel

for domestic and industrial purposes has increased the frequency of accidental explosions due

to leakage and thus leakage of LPG is a serious problem as very small quantity of gas up to

1.8 volume % is the lower explosive limit and 13 % gas mixed in air shows upper explosive

limit. The normal constituents of LPG are a feed stock fuel which consists of hazardous

ingredients such as, methane, propane and butane etc. It is highly inflammable, hazardous,

toxic and explosive in nature and hence it is necessary to sense and detect LPG before

causing serious accident and to perform active suppression.

To use heterojunction as a

LPG sensor, we have

developed laboratory made

unit as shown below. We

have successfully developed

hetero-junction between

chemically deposited n-Bi2S3 /

p-CuSCN layers at room

temperature without any heat

treatment step and used as

liquefied petroleum gas (LPG) sensor at room temperature. Room temperature LPG detection

with gas response of 70.7 % at 1370 ppm (higher sensitivity value) was obtained and which is

remarkable achievement. The results are published in J. Phys. D: Appl. Phys. 43 (2010)

245302.

PATENT APPLIED: n-TiO2 and p-CuSCN as a heterojunction partners for detection of

Liquefied Petroleum Gas (LPG) at room temperature

Research work done abroad

A) As Research Associate (USA)

A carbon nanotube is a one-atom thick sheet of graphite (called graphene) rolled up into a

seamless cylinder with diameter of the order of a nanometer. This results in an essentially

one-dimensional nanostructure where the length-to-diameter ratio exceeds 10,000. Such

cylindrical carbon molecules have novel properties that make them potentially useful in a

wide variety of applications in nanotechnology, electronics, optics and other fields of

materials science. They exhibit extraordinary strength and unique electrical properties, and

are efficient conductors of heat. Inorganic nanotubes have also been synthesized. There are

two main types of nanotubes: Singled-walled nanotubes (SWNTs) and Multi-walled

nanotubes (MWNTs).

Applicant worked with the commercially available SWNT and their use to develop

SWNT/polymer composite film and also with iodine doping. He obtained a record

conductivity for the iodine doped SWNT/polymer composite films and the results are

published in the journal “Applied Physics Letters 91 (2007) 173103”.

B) As JSPS Postdoc Fellow (Japan)

Applicant worked as a JSPS (Japanese Society for the Promotion of Science)

Postdoctoral Fellow in Gifu University, Japan. The fellowship is for two years. The topic of

postdoctoral research was on Development of Solid-State Dye Sensitized Solar Cell.

Fig 2 This was based on use of one step electro-synthesized

nanoporous ZnO towards application in photovoltaic devices. This

nanoporous ZnO film consisting of high crystalline and highly

oriented hybrid crystal in a sponge-like structure enabling high

surface area led to the high expectation in its applications in DSSC

(Fig.1 LHS-surface & RHS-cross-sectional morphology). This high

surface area structure can be utilized to form solid-state device

using different dyes. Usually for dye sensitized solar cell, Ru-dye

has been used which is too costly. Now we are using the dyes like

Eosin Y, Cumarin 343, D102, D149, and Rose Bengal which are

cost effective. Using these dyes we are developing the device with

the structure FTO/ compact ZnO/nanoporous ZnO/dye/p-type

materials (CuSCN, CuI etc) [figure 2]. This whole system is based

on low temperature electrosynthesis materials preparation without

further post-heat treatment at higher temperature. Moreover, the

use of Eosin-Y as dye overcome the use of Ru-metal free and also

does not involve high mechanical stress nor aggressive chemicals,

being perfectly compatible with conductive plastic substrate, enabling flexible solid-state dye

sensitized solar cells with low cost investment in future work.

Instead of dye, we are tried to use narrow band gap semiconductor (e.g. CdSe) (also termed

as pigment sensitized or extremely thin film absorber, ETA). The main advantage of this

sensitized structure is that the region in which light excites electron is separated from that in

which charge is transported, the recombination rate is then largely decreased and the

photoelectric conversion efficiency is increased. Furthermore the band gap of the

nanocrystals can be tuned by controlling their size so that the absorption spectrum can be

tuned to match the full spectrum of solar energy.

Along with this work, the research on using polymers like P3HT, P3P7HT, PEDOT (spin

coating /drop coating) on nanoporous ZnO have been done and their photovoltaic properties

have been studied. Also, applicant partly worked on the dye sensitized solar cells on flexible

substrate to get acquainted with the techniques available. One of the solar cell flexible

module used for working solar car is shown here.

C) Research work done on European CISLINE Project

(Germany)

The applicant worked on the CISLINE European project entitled

“Improved CISCuT Solar Cells, Manufactured Roll-to-Roll in a Base

Line” in the Hahn-Meitner-Institut, Berlin, Germany. This European

project was related with transformation of a laboratory-scale achievement

into a low cost CISCuT technique to manufacture CuInS2 (CIS) on Cu-

tape (RHS figure) on the flexible substrate (Cu tape) to develop solar cell on the roll-to-roll

basis. This CISCuT solar cell had the structure Cu-tape/n-type CuInS2 (absorber) /p-type CuI

(buffer)/ ZnO window layer. In the project, the main coordinator (IST, Frankfurt, Oder) was

developing the device. In this device, they used p-CuI as a buffer layer, which was prepared

by dissolving CuI in acetonitrile and spraying on CISCuT absorber at higher temperatures

(>150 oC) which was toxic.

In this concern, our work was aimed to search the alternative ways to produce p-type

wide band gap semiconducting materials (e.g. CuI, Cu2O) with low toxic materials and the

synthesis method should be applicable to roll-to-roll process on flexible substrate. We used

Successive Ionic Layer Adsorption and Reaction (SILAR) method at room temperature to

deposit CuI. SILAR method was compatible for roll-to-roll production since it is based on

immersion of the substrates in to separately place cationic and anionic precursors.

Achievements: Applicant succeeded to deposit CuI thin films from aqueous media at room

temperature (25 oC) using the SILAR method. Efficiencies up to 4 -5 % were achieved with

maximum quantum efficiency of 60 % for SILAR deposited CuI on CISCuT absorber.

Besides of this project work, applicant synthesized thin films of TiO2, TiO2-SiO2 and

ZnS films. ZnS films showed more than 12 % efficiency when used as buffer layer in CIGSS

based solar cells.
