Scientists in India have simulated a perovskite cell based on methylammonium tin iodide which they claim may achieve a short circuit current density of 25.97 mA per square centimeter, an open-circuit voltage of 1.203 V, and a fill factor of 87.79%. The cell is composed of a fluorine-doped tin oxide (FTO) substrate, a titanium oxide layer, a methylammonium tin iodide perovskite film, a copper oxide hole transport layer (HTL), and a layer made of gold (Au).
Bidders have until April 29 to lodge their interest to install and commission a 20 MW ground-mounted solar project for Central Coalfield Limited (CCL). The plant shall come up at CCL’s coal handling and preparation plant in Piparwar village. Solar cells and modules of any origin are allowed for the project.
The solar plant in the Jamshedpur city of Jharkhand is expected to generate an average 32 million units of electricity per year, offsetting approximately an average 25.8 million Kg of CO2 annually.
March 30 is the last date to bid for the solar capacity tendered by NTPC Vidyut Vyapar Nigam Limited. The project—to be set up on turnkey basis—shall come up at Panchet power station of Damodar Valley Corporation and shall be awarded through domestic competitive bidding followed by reverse auction.
Developers have until January 15, 2020 to submit bids for the project that shall come up at Central Coalfields Limited’s plant in Piparwar of Jharkhand.
Bids can be submitted till December 27 for the project which shall come up at the state-run power producer’s Panchet project in Dhanbad district. The project shall be awarded through tariff-based domestic bidding followed by reverse auction.
Prospective developers have until November 18 to submit bids for standalone PV systems, with inverter and lead-acid batteries, at various government high schools, health sub-centres and Anganwadi Centres.
Bids are invited for design, supply, installation and commissioning of solar home cooking systems in five districts of different states (Meghalaya, Chhattisharh, Jharkhand, Uttar Pradesh and Gujarat). Bidding closes on November 8.
The chargers will be set up in six cities (Agra, Bengaluru, Goa, Hyderabad, Ranchi, Shimla) and along Delhi-Jaipur-Agra-Delhi and Mumbai-Pune-Mumbai highways.
