India-Japan team ups photovoltaic cell efficiency

The cost of production of a megawatt of solar power is high. The efficiency of conversion of sunlight into energy by existing solar cells also must be improved considerably. These two factors are limiting the expansion of solar power as compared to standard sources like thermal and hydel energy.

There is some excellent news on the technology front. An Indo-Japanese research initiative has reported a lift within the conversion efficiency of dye sensitised solar cells (DSSC) to 11.4 per cent. to realize this, they need developed a replacement material (a co-adsorbent).

India-Japan team up to improve solar cell efficiency

This is the very best certified efficiency, breaking the record set five years ago. The work has been administered at the Indian Institute of Chemical Technology (IICT), Hyderabad, and Japanese researchers and reported within the journal Energy & ecology of the Royal Society of Chemistry.

DSSCs are easy to fabricate and utilise low-cost materials. it’s emerging as an alternate to the primary generation of silicon solar cells, which are expensive. The IICT plans to develop new co-adsorbents with structural modifications to further increase efficiency thereto of silicon-based solar cells and make them competitive, he told line .

Stating this, Malapaka Chandrasekharam, senior scientist at the IICT, said DSSC technology with its low fabrication costs will become a big player in future large-scale solar power conversion. Compared to silicon-based cells, the main advantages of those cells are — they’re cheap, flexible and may be operated even under diffused light.

Multinationals like G24 Innovations in Wales have established large production facilities for flexible DSSCs.

The IICT-Japanese research work has been independently certified by the Advanced Industrial Science and Technology, Tsukuba, Japan. it’s focussed on developing new materials for DSSC technology with higher efficiency and long durable properties.
