Photovoltaic (PV) technology has witnessed remarkable advancements, revolutionizing solar energy generation. This article provides a comprehensive overview of the recent developments in PV technology, highlighting its improved efficiency, affordability, and accessibility.
The history of solar energy technology began with the production of the first PV cell at Bell Labs in 1954. This first-generation solar technology panel, which had a six per cent efficiency, marked the birth of solar energy harvesting. It only successfully turned a small fraction of the photons that hit it into electricity.
Benefitting from favorable policies and declining costs of modules, photovoltaic solar installation has grown consistently. In 2023, China added 60% of the world's new capacity. Between 1992 and 2023, the worldwide usage of photovoltaics (PV) increased exponentially.
The United States, where modern solar PV was invented, led installed capacity for many years.
While it might seem like it, solar panels are not a new invention. In fact, they were first invented in the late 1800s, which seems like an incredibly long time ago for a technology that we’re still not using everywhere.
A steady trend in technology improvements is observed, with crystalline solar PV being the dominant technology in the market. Increasing scales of production have also led to significant cost reductions in the per watt cost of solar modules.
