The solar industry is growing rapidly in India and worldwide. Recognizing this momentum, the Maharashtra government is actively supporting a ground-breaking project from IIT Bombay (IITB). The initiative has successfully enhanced solar cell efficiency to thirty percent by integrating perovskite with conventional silicon solar cells.
Potential for Even Greater Efficiency
According to IITB, this efficiency could potentially rise to forty-five percent. The Maharashtra Institution for Transformation (MITRA), the state’s policy think tank, is championing the project. MITRA views this innovation as a disruptive technology that could boost India’s self-reliance and position the country as a global leader in next-generation solar energy solutions.
Innovative Solar Technology by IIT Bombay and ART-PV India
IITB, in collaboration with ART-PV India—a startup incubated within SINE-IITB—has developed a 4T silicon-perovskite tandem solar cell. This advanced solar cell not only generates more electricity using fewer cells but also significantly reduces costs compared to traditional solar cells.
Addressing Stability Challenges in Perovskite Solar Cells
Professor Dinesh Kabra of IITB explained, “Perovskite solar cells offer high power conversion efficiency and low production costs. However, they previously lacked stability and degraded faster than conventional solar cells. We have successfully fabricated a stable perovskite tandem solar cell that increases solar efficiency to 30%. Based on simulation studies, we believe this efficiency could reach up to 45%”.
As reported by thehighereducationreview.com, the breakthrough in solar technology could revolutionize the industry, making solar energy more efficient, affordable, and widely accessible.
