TOPCon shingle solar cells: Thermal laser separation and passivated edge technology

Efficient passivated phthalocyanine-quantum dot solar cells.

The power conversion efficiency of CdSe and CdS quantum dot sensitized solar cells is enhanced by passivation with asymmetrically substituted phthalocyanines. The introduction of the phthalocyanine dye increases the efficiency up to 45% for CdSe and 104% for CdS. The main mechanism causing this improvement is the quantum dot passivation. This study highlights the possibilities of a new generati...

Mechatronics Technology for Solar Cells

A mechatronic real-time solar tracker is developed with National Instruments Compact Rio programming module, photoresistors sensor, stepper motors, and a set of nickel metal hydride (NiMH) cells. The tracking array is able to pivot on two axes by way of the stepper motors to reflect the effect of daily and seasonal trajectories of the sun. This design will keep the solar cell perpendicular to t...

Potential of Solar Thermal Technology and its Status in India

For economic development and generation of wealth, energy plays a significant role. Energy is available in two different alternatives, non-renewable and renewable sources. The need for new sustainable energy supply options that use renewable energies are emphasized due to limited fossil fuels and environmental problems associated with it. In recent years, solar energy has received great deal of...
