Tellurium Price — 10-Day Trend Behind CdTe Demand
All prices in ₹ per gram · daily rate, updated once per day
The One Solar Technology That Actually Needs Tellurium
Cadmium telluride, usually shortened to CdTe, is a semiconductor compound built from cadmium and tellurium. It forms the light-absorbing layer in thin-film solar panels, a real and commercially established alternative to the silicon panels most people picture when they think "solar." No other current use pulls anywhere near as much tellurium out of the market as CdTe manufacturing does, and that single fact is why this page exists as its own topic rather than a bullet point buried in a broader uses list.
Today's benchmark rate sits at ₹10.42 per gram. Scale that up and the numbers that actually matter to industrial buyers come into focus: 104.16 per 10 grams, 1,041.57 per 100 grams, and 10,415.66 per kilogram. There is no coin, bar or jewellery-counter market behind any of these figures — tellurium trades purely as a specialty industrial material, and CdTe panel manufacturers are its biggest buyers by a wide margin.

CdTe vs Silicon: How the Two Technologies Actually Differ
Silicon dominates the solar industry, and for good reason — it is mature, well understood, and manufactured at massive scale worldwide. CdTe was never built to dethrone silicon outright. It carved out a real, durable share of the market by taking a genuinely different manufacturing path, one that happens to lean entirely on tellurium instead of purified silicon wafers.
| Attribute | CdTe Thin-Film | Crystalline Silicon |
|---|---|---|
| Core semiconductor material | Cadmium telluride, deposited as a thin film | Purified silicon, sliced into wafers |
| Manufacturing approach | Layers deposited directly onto glass in a largely continuous process | Ingots grown, then cut into individual wafers |
| Typical panel efficiency | Competitive with, though historically somewhat below, standard silicon panel efficiency | Industry benchmark; generally the higher end of commercial panel efficiency |
| Key raw-material dependency | Tellurium — a scarce copper-refining byproduct | Silicon — abundant, refined from ordinary quartz sand |
| Best-known large-scale producer | First Solar (NASDAQ: FSLR) | Multiple global manufacturers |
Why the semiconductor itself behaves differently in the field
Cadmium telluride has a higher bandgap than silicon — roughly 1.45 electronvolts against silicon's roughly 1.12. That is not a trivia detail. A higher bandgap tends to hold up better under heat and in diffuse, overcast light, which is one reason CdTe panels have found a genuine niche in hot-climate, large-scale installations rather than losing outright to silicon everywhere. First Solar, a NASDAQ-listed American manufacturer trading under the ticker FSLR since 2006, built its entire business around exploiting that difference at utility scale.

What Growing CdTe Manufacturing Could Mean for Tellurium
Global solar installation has expanded substantially over the past decade, and CdTe has held its ground as a real, cost-relevant alternative path rather than fading into a footnote next to silicon. If that trend continues, demand pressure on tellurium's supply could keep building — though nothing here should be read as a promise about where the price goes next. Tellurium's own supply, recovered only from copper-refining anode slimes, has no easy way to expand simply because a solar manufacturer wants more of it.
There is no way to buy CdTe exposure directly through tellurium itself; the closest real option is a company like First Solar or a copper refiner that recovers tellurium as a byproduct, and both carry business risks that have nothing to do with the tellurium price on any given day. For the raw historical numbers behind today's ₹10.42 per gram, the site's own tellurium price history page tracks the year in full, and the anode slime production story covers exactly where this material comes from before it ever reaches a solar panel.
Cadmium Telluride Solar Panels — FAQs
CdTe is a compound of cadmium and tellurium used as the light-absorbing semiconductor layer in a specific type of solar panel called thin-film photovoltaic. It is the single largest modern consumer of tellurium, which is why shifts in solar panel manufacturing plans move tellurium demand more than any other end use does.
It is a genuine, commercially established alternative, not a fringe experiment. CdTe module efficiency is competitive with, though historically somewhat below, standard crystalline silicon panel efficiency, and entire utility-scale solar farms are built using it.
Yes. First Solar, Inc. is a publicly traded American company, listed on the NASDAQ under the ticker FSLR since 2006, and it is the best-known large-scale manufacturer of CdTe thin-film solar panels.
Silicon panels are built from wafers sliced from grown ingots of purified silicon. CdTe panels skip that step — the semiconductor material is deposited as a thin film directly onto a glass sheet in a more continuous manufacturing process, using far less semiconductor material per panel.
Yes, directly. Tellurium's supply is already narrow, since it is only recovered from copper-refining anode slimes, and CdTe solar is its dominant single use. A pickup in CdTe module manufacturing presses against a supply base with no easy way to expand on short notice.
