IIT Roorkee and CSIR-NCL jointly develop dyes to increase efficiency of solar cells

Researchers from IIT Roorkee have developed organic dyes in collaboration with CSIR-NCL Pune that can increase the efficiency of Dye-Sensitised Solar Cells (DSSC).

The team of researchers led by Dr. M. Sankar, Associate Professor, Department of Chemistry, IIT Roorkee, have worked to improve the photovoltaic conversion efficiencies of an organic dye called porphyrin for DSSC applications.

Their latest research results have been published in a journal of the American Chemical Society (ACS) called ACS Applied Energy Materials.

Solar cell technologies fall into three generations; the first and second generations comprise photovoltaic cells that use inorganic semiconducting materials such as single crystal silicon (Gen I) and thin film silicon and CdSe type semiconductors (Gen II).

Inorganic semiconductors of both generations continue to be expensive and challenging for scale up.

The third generation, which is in the research stage, includes dye-sensitized solar cells or DSSC, which use a combination of cheap organic dyes and nanoparticles of titanium dioxide, to convert light into electricity.

Although the cost of DSSC is much lower than the earlier generations of photovoltaics, their conversion efficiencies are also very low, necessitating further research into dyes used in such cells.

Porphyrin is a complex organic molecule and is the building block of chlorophyll, the key chemical that allows plants to harvest light energy for photosynthesis.

The first study on the use of porphyrins in DSSC dates back to 1993, in which, porphyrin containing copper, resulted in power conversion efficiencies of 2.6%, too low for practical applications.

Since then, various modifications of porphyrin have been studied for use in DSSC. Zinc-containing porphyrins have been found promising and the research team at IIT Roorkee uses this type of porphyrin for its studies.

One way of improving the efficiency of the dye is to add molecular pendants or groups to it, which can result in a ‘push-pull’ architecture that involves the shuttle of electrons released in the molecule.

Such push-pull mechanisms also improve the absorption of light in the red and infrared regions, thereby increasing the efficiency of the dye in photo-electric conversions.

For dye molecules like porphyrin, these functional groups are introduced through reactions that involve many complex steps and need expensive palladium and platinum-based catalysts. Compounds made by these reactions have low efficiencies.

Dr. Sankar and the research team have developed a process to produce functionalized porphyrins, without the use of platinum and palladium catalysts.

“Our continuous efforts to develop simple, efficient, stable, and cost-effective sensitizers involving fewer synthetic steps have resulted in five porphyrins Zn(II) complexes with a power conversion efficiency ranging from 5.3% to 7.1%”, explains Dr. Sankar
“We have also shown the scalability of the synthetic approach”, he adds, on the advantage of the method developed.

The researchers have used the Density Functional Theory (DFT) calculations to understand the electron density distribution in frontier molecular orbitals (FMOs) and for geometry optimization.

They have studied the photoelectric properties of the dyes by standard methods such as optical and fluorescence spectroscopy, cyclic voltammetry, impedance spectroscopy and PV measurements, all of which have shown improved performance of the dyes.

Aggressive research all over the world on improving the light-to-energy conversion efficiencies of DSSC has made it a credible competitor to first and second generation solar cells.

This collaborative work by IIT Roorkee and CSIR-NCL on the improvement of sensitizers for DSSC could lead to dyes with higher conversion efficiencies, which in turn could lead to better and low-cost DSSCs than possible today.

The research team comprises Ravi, Kamal and Dr Sankar from IIT Roorkee and Sudhakar, Dr Krishnamoorthy from CSIR-NCL, Pune.

CEA working on optimized power system cost for 2030

CEA working on optimized power system cost for 2030

The Central Electricity Authority (CEA) has undertaken a study to ascertain the cheapest power mix in 2030, its Chairman Pankaj Batra said.

“We are working on what should be the ‘Ideal System Cost’ in 2030 and a report is expected in a month’s time,” Batra told .

The report will try to find out the cheapest power mix with grid stability in 2030, and would give a direction to the power sector developers, he said.

The outcome of the study will also act as components to the regulators in determining power tariffs.

According to estimates by the Ministry of Power, the share of renewable energy in India’s electricity mix is set to increase to around 55 per cent by 2030.

At present, renewables account for nearly 20 per cent of the total installed capacity.

India has committed to produce about 40 per cent of its installed electricity capacity from non-fossil fuel sources by 2030. It has also set a target of adding 175 GW of renewable energy capacity by 2022.

Meanwhile, the CEA is also closely working with stakeholders in building a cost-effective power evacuation infrastructure in Leh and Ladakh region of Jammu and Kashmir.

“The region holds potential for 35,000 MW of solar power. We need to build a cost-effective evacuation transmission network before the solar projects are awarded there,” Batra said.

It can be executed by a combination of underground cables and towers installed by airlifting, he said.

The Jammu and Kashmir government has already signed an MoU with the Centre for development of two mega solar parks with a total capacity of 7,500 MW in the Ladakh region.

The Government should offer an incentive to help India achieve solar power target by 2022: LSI

The Government should offer an incentive to help India achieve solar power target by 2022: LSI

Rating agency Crisil had, in its last report, said India will not be able to achieve its ambitious target of generating 100GW solar power by 2022

New Delhi: Sebi approved merchant banker LSI Financial Services feels Indian government should contemplate offering financial stimulus including price incentives and subsidized credit to domestic solar cell and module manufacturers.

The incentives will not only make the country’s module manufacturers globally competitive but also help India achieve its ambitious National Solar Mission target to add 100 gigawatts (GW) of solar power capacity by 2022, the merchant banker’s research arm said in a report. India is the world’s third-largest energy consumer after the US and China with the current solar power capacity at about 24GW.

Rating agency Crisil had, in its last report, said India will not be able to achieve its ambitious target of generating 100GW solar power by 2022. In its report, Crisil’s industry research arm said that in the best-case scenario, the country will touch 78-80 GW, against the current capacity of 21.65 GW. Crisil expects an additional 56-58GW of solar capacity addition between fiscals 2019 and 2023. While this is a vast improvement from the 20GW added during 2014-18, it still falls short of the National Solar Mission target by a fifth.

Institutional and regulatory bottlenecks like the imposition of safeguard duty on solar modules from China and Malaysia, which took effect this month and will continue for two years, is expected to slow capacity addition, the report stated.

Elaborating further, the report said uncertainty regarding the safeguard duty is making developers wary about project viability as the imposition of duties will increase the price of imported solar modules compelling manufacturers to either downsize or exit from the market. Investors and banker confidence will also suffer a setback and quite a few solar projects may get scrapped, the report added.

The government, on July 30, ordered safeguard duty of 25 percent on solar panels and modules imported from China and Malaysia to protect domestic manufacturers and to encourage solar project developers to buy units locally. However, faced with mounting pressure from solar power developers, the duty has been temporarily lifted. About 90 percent of the solar cells and modules used in India are imported from China and Malaysia, according to industry estimates.

Industry experts believe that the safeguard duty will raise capital costs by 15-20 percent. Solar power tariffs in India plunged to a record low of Rs 2.44 per unit in July due to a decline in module prices and improvements in capacity utilization. The declining tariffs have attracted good investments but have raised concerns over the long-term sustainability of the projects.
