Work experience

 Providing strategic guidance and support to member countries with energy transition and technology development.

Collaborating with international stakeholders - policy makers, industry experts, researchers, etc. to drive innovation and sustainability in the solar energy sector.

Working on portfolios including Integrated PV- AgriPV, Floating PV, BIPV, and PV waste Management.

Leading a special guest issue on 'Integrated PV applications' in Solar Compass (Elsevier journal) as Guest Editor

Led PV system reliability and degradation based experimental studies (in climatic chambers for humid, UV and salt mist condition) in harsh environments for Floating PV and Agri PV applications

Assisted in development of pilot Floating PV demonstrator at CRES and other pilot sites in France

Coordinated international R&D collaborations for PV modules reliability testing (with CEA, and Fraunhofer ISE)

Conducted review of market standards for Floating PV and Agri PV installations to foresee potential reliability concerns

Developed tunnel junctions (nc:Si:H, polySi, a:Si:H, µc-SiOx..) by PECVD for high efficiency (above 30%) c-Si/Perovskite tandem solar cells

Developed first in-house fabricated Si/perovskite tandem solar at IPVF with efficiency above 18%

Mentored PhD students and interns for projects on silicon passivation and heterojunction cells

Contributed to the benchmark of existing c-Si technologies for internal needs (prototyping, market studies, integration in modules, etc.)

Acted as the technical support in collaboration with key industrial and academic players including CNRS, TotalEnergies, and EDF

Studied and developed novel ultra-thin dielectric layers- SiOx, AlOx, TiOx and SiNx  using Spatial ALD, PEALD, LPCVD, PECVD and wet chemical deposition methods for application in industry relevant passivated contact technologies

Pioneered successful deployment of 2 nm thick PE-ALD and LPCVD SiNx films in highly electron selective SiNx/poly-Si contacts for achieving ultra-high efficiency solar cells; this approach resulted in 1.2% higher efficiency compared to standard SiOx/poly-Si contacts

Conceptualized and synthesized biodegradable, dopant free, organic material alternatives (tunnel layer/PEDOT:PSS) for high efficiency solar cells; it has a potential to reduce the annual production costs by ~25% and environment benefits

Investigated and tabulated a comparative analysis of product portfolio with 100+ solar products (industrial and domestic use) in Germany, India and Singapore

Led a team of 3 Young India Fellows to conduct policy infrastructure analysis of central and state government policies in India aiding the power generation and distribution of solar energy

Coordinated  and developed strong interfaces with various stakeholders – government, solar investors, PV manufacturers, project developers,  dealers, distributors and end users to understand the gaps in the process chain

Directed product development from ideation to mobile application for providing maintenance services, and trained manpower in India

Designed a school monitoring system to capture real time data points for school infrastructure, student matrix, teacher matrix, parental participation, mid-day meal scheme, etc. of private and public schools in India

 Analyzed the education policies in India and abroad, and developed a comparative standard for data collection

Ran a pilot in two government schools in Delhi along with Saanjha using above matrix

Synthesized large grain poly-Si thin films of solar cell quality using Hot Wire CVD system on cheap glass substrates with potential to reduce the cost by 30% under guidance of Prof. Brij Mohan Arora (Chair Prof. @IIT Bombay, former Prof. @TIFR)

Characterized films using optical (transmission & reflection) spectroscopy, AFM, SEM, XRD, Raman scattering, temperature dependent electrical resistivity in dark and photoluminescence. 

Improved the photoconductivity of the thin films by 20% by an in-situ soak in atomic hydrogen 

Yielded 1 conference contribution (40th IEEE PVSC-2014) and 1 publication (IEEE Xplore)

Examined the influence of temperature and anchor atoms (S, Se) on the conductance properties of saturated alkanes (Propane (C-3) to Decane (C-10)) chains using Atomistic Toolkit -Virtual Nanolab

Identified Butane as a potential candidate for molecular switch due to low resistance was awarded A+ (highest grade) in seminar and Best Seminar Award

Yielded in 2 conference contributions and 1 Appreciation Award at 3 Minute Thesis competition (Padarth-IITB) at national level 

Extended PIE (Physics Interactive Experiment) Framework to 2.5D framework -an improvement of Action Script 3 and implemented 3D & Independent motion in PIE

Developed more than 250 animated physics experiments for 6th-10th standard kids using PIE Framework under guidance of Padam Shri Prof. D.B. Phatak (IIT Bombay).
