PV technology currently uses conventional Silicon Solar which has many limitations in terms of efficiency, throughput, costs etc. to meet the increased global energy demands. ART-PV India has a vision to research and make new generation Photovoltaic Technology based on Tandem Solar Cells , a sustainable green energy solution.The Tandem PV systems have increased power conversion efficiency, lower wattage costs, flexible and lightweight solar modules. They promise high throughput for commercialization and in situ metrology for quality control using smart machine learning.
1. Terrestrial Solar PV Application
One of our primary application focus areas has been Perovskite -Si tandem for terrestrial solar PV application. The global solar PV market is valued at approximately USD $331 Billion to $407 Billion and projected to surge past USD $689 Billion to $832 Billion by 2033–2035 (growing at a steady CAGR of ~8.5% to 10.8%). In India only the installation capacity of solar PV is mandated to reach beyond 300 GW by 2030 from the current capacity of ~160 GW. This implies massive market opportunity for solar PV.
Traditional single-junction silicon solar panels dominate the market; however, they are limited by the practical efficiency limit of 29%. As land costs rise and grid demands surge, the world desperately needs more power from less space. One obvious solution is layering a high-bandgap perovskite cell over a proven silicon base in tandem. Tandem architecture captures a wider spectrum of sunlight, smashing through silicon’s efficiency ceiling to unlock power conversion efficiencies exceeding 30-33%. By integrating seamlessly with existing silicon manufacturing backplanes, it can deliver more than 30% power conversion efficiency at module level. This significantly lowers the Levelized Cost of Energy (LCOE) for utility-scale solar farms and maximizes energy yields for space-constrained commercial and residential rooftops.
At ARTPV, our primary focus has been in improving perovskite Si solar cell efficiency and stability to meet the terrestrial field deployment requirement. With our proven technology and scale-up road map for large scale manufacturing, we aim to be market ready with our solar PV solution in the next 2 to 3 years timeline.
2. Space Grade Solar PV Solution
Space-grade solar cells are specialized, highly efficient photovoltaic devices designed to power spacecraft. Unlike terrestrial panels, they are built to withstand extreme temperatures, a near-vacuum environment, and harsh cosmic radiation. They primarily utilize advanced multi-junction (Gallium Arsenide) technology to achieve ultra-high conversion efficiencies of over 30%.
However, traditional GaAs based solar cells used for space applications are limited by cost and availability. This has opened up opportunities for other materials and device platforms like Perovskite- Si tandem solar cells. Perovskite-Si tandem solar cells can meet the requirement of specific power required for Space Cells i.e. is ~1 W/g with comparatively lesser cost than current standard (>100 $/W).
At ARTPV, we have been in the forefront for research and development of space grade Si-Perovskite solar cells. We have been working on radiation shield, radiation and thermal cycling tolerant material combinations and vacuum shielding to enable space deployability.
We anticipate that with our innovative technology, our solar cells will be ready for space deployment in the next two years.
3. Detectors
Metal halide perovskites can be used for photodetectors and direct X-ray sensors with unprecedented sensitivity across the spectrum—from visible light to high-energy radiation.
For optical applications (UV-Vis-NIR), metal halide perovskites with band gap tunability, exceptionally high absorption coefficients and high charge carrier mobility, will lead to fast, high-quantum-efficiency light sensors for machine vision and optical communications.
Heavy-atom perovskite thick films can act as direct X-ray absorbers. By bypassing traditional, scattering-prone scintillators, our sensors convert X-ray photons directly into sharp electronic signals. It would leap forward the spatial resolution, drastically lower detection limits, and minimal dark current drift for mission-critical imaging.
We aim to combine semiconductor-grade performance of Perovskite thin film device with scalable, low-temperature manufacturing there by reducing system costs while scaling up resolution for medical imaging, industrial inspection, and advanced optical sensing.
