Bifacial Solar Cells: Structure & Working

 

Description

Learn about bifacial solar cells, their structure, PERC vs TOPCon architecture, bifacial gain, efficiency, and applications.

Introduction

Bifacial solar cells generate electricity from both their front surface (direct and diffuse sunlight) and their back surface (reflected albedo light from the ground and surroundings). Modern bifacial solar technology based on PERC (Passivated emitter and rear cell) and TOPCon (Tunnel oxide passivated contact) architectures, accounting for over 80% of new global PV installations as of 2024.

Tandem Solar Cells: Working Principle, Structure, Efficiency & Advantages

 

Description 

Learn about tandem solar cells, their working principle, structure, efficiency, advantages, challenges, and future.

Introduction

The theoretical limits of single solar cell are 30%. The William Shockley and Hans Joachim Queisser made discovery about 50 years ago, called it Shockley – Quisser limit. They theoretically calculated that solar panels with one single layer suffer efficiency limitations as they are unable to absorb full solar light. In the tandem cell, two solar cells stack one on top of the other in which top cells are transparent, convert high energy photons into electricity. The bottom cell absorbs lower energy photons. The solar spectrum splits into two layers dramatically reduces thermalization losses. This will enable theoretically efficiency far better than single layer cells.

Perovskite Solar Cells: Structure, Working Principle, Advantages, Efficiency & Future (2026)

 

Introduction

Perovskite solar cells (PSCs) are among the most promising next-generation photovoltaic technologies. They use a metal-halide perovskite absorber with an ABX3 crystal structure. Since 2009, their certified efficiency has rapidly increased from 3.8% to over 26%, making them one of the fastest-developing solar technologies.

FAME II Scheme Explained – Objectives, Incentives & Benefits

FAME II Scheme: Complete Guide to India’s Electric Vehicle Policy

The FAME II Scheme (Faster Adoption and Manufacturing of Electric Vehicles in India) is one of India’s most significant initiatives to promote electric mobility and reduce dependence on fossil fuels. The scheme encourages the adoption of electric vehicles through financial incentives, charging infrastructure development, and support for domestic manufacturing.

The Government of India launched this scheme to accelerate the transition towards clean transportation while reducing air pollution and greenhouse gas emissions.
