A watan jiya na ziyarci wata [TOPCon](https://www.ooitech.com/what-is-topcon-solar-cell-a-complete-guide-to-tunnel-oxide-passivated-contact-technology.html) masana'anta. Tsohon Zhang, shugaban tsari, yana shafa hannayensa bayan ya cire sabon allo daga firinta, yana yin lissafi da ni da baki.

"Wani allo na waya karfe na PI-film yana kashe **4,000 zuwa 8,000 yuan**, kuma a fadin masana'antar, tsawon rayuwa yawanci kusan **400,000 wafers**. Mai kyau ya kai 450,000, mara kyau yana zubar da man a 300,000. Idan aka raba kan kowane wafer, wannan ya zama centi ko biyu. Kana tunanin na damu da kudin allo?"

Ya jingina da akwatin kayan aiki kusa da na'urar bugu, ya rage muryarsa: "**Man azurfa shine ainihin labarin.**"

Farkon 2023, azurfa tana kusan **Naira 6,000 a kowace kilogiram**, kuma man azurfa ya kasance kawai **3.4%** na farashin module. Zuwa wannan watan Janairu, man ya haura zuwa **29%** na jimlar farashin module. Man azurfa a hukumance ya wuce polysilicon a matsayin babban abin da ke haifar da farashi a cikin module na PV.

A ranar 23 ga Yuni, azurfa na spot ya kasance **15,233 yuan/kg**, kuma man azurfa na gaba mai kyau ya yi farashin **15,779 yuan/kg**.

"Kashi 29 cikin dari!" Ya buga ƙofar kabinet. "Muna ƙoƙari sosai wajen rage farashi da inganta aiki, amma har yanzu bai kai kwana ɗaya na canjin farashin azurfa ba."

Ya fitar da wayarsa ya nuna mini wani jadawali na ciki: farashin man azurfa na gaba a cikin shekaru uku da suka gabata, kusan hawan digiri 45 madaidaici.

"Ka ga waccan takardar buga farantin karfe?" Na tambaya.

"Na karanta ta. Wannan na Joule daga Cibiyar Kayan Aiki ta Ningbo. Duk rukunin layin samarwa sun watsa ta. Amma gudanarwa har yanzu tana shakka, domin a ƙarshe, **shin wannan abu zai iya adana kuɗi da gaske?**"

## Fa'idodin Fasaha

### One: Steel Plate Printing Is More Than Swapping a Screen

Conventional TOPCon front grids use **screen printing**, where a woven mesh scrapes silver paste onto the wafer. That woven mesh has knots where warp and weft cross, and paste transfers through the gaps between them. **Those knots dictate the grid shape: wide, short, sloped edges.**

**Steel plate printing** yana amfani da stencil na ƙarfe mai cikakken buɗewa, irin wannan fasaha da Tongwei ke kira "bugu na farantin ƙarfe mai cikakken buɗewa." Babu saƙa. Manna yana fitowa kai tsaye ta cikin buɗeɗɗen da laser ko electroforming suka buɗe. Siffar grid tana canzawa nan take:

- Bugu na allo: 17.0-19.4 μm faɗi, 8.7 μm tsayi, girman rabo **45.1%**, gefuna masu gangara.
- Bugu na farantin ƙarfe: 14.1-15.5 μm faɗi, 8.9 μm tsayi, girman rabo **58.9%**, gefuna kusan a tsaye.

**3-4 μm ƙarami, 0.2 μm tsayi, girman rabo daga 45% har zuwa 59%.**

Canje-canje uku, asusu uku don daidaitawa:

**Na farko, ƙarancin inuwa.** Ƙananan yatsu, ƙarin buɗe wuri don haske. Wannan **0.1% cikakken ribar inganci** ya fito daga waɗannan 3-4 microns.

**Na biyu, ƙarancin azurfa.** Ɗauki **210R** cell. Bayanan filin na Yuni 2026 sun nuna manyan masu yin TOPCon sun riga sun kai **78.5-85.5 mg/wafer**, matsakaicin masana'antu kusan **83 mg/wafer**. Tare da allon karfe, babban amfani a yanzu shi ne a kan **rear busbar/finger**, yanke **3-5 mg** a kowace wafer.

3-5 mg yana da kadan, amma idan ka ninka shi da yawan layin, yana ƙaruwa. A farashin paste na yanzu na kusan **15,779 yuan/kg**, ceton 3-5 mg a kowace wafer yana kusan **0.047-0.079 yuan/wafer**. Layin da ke gudanar da wafers 500,000 a rana yana ceton **23,500-39,500 yuan a rana**, ko **miliyan 7 zuwa 12 yuan a shekara** (fiye da kwanaki 300).

Kuma wannan shine kawai raguwar finger na baya. Yayin da tsarin ke girma, bugu na karfe yana motsawa zuwa busbar na gaba da kuma grid mai kyau, tare da ƙarin ceton azurfa a gaba.

**Na uku, yana sa hanyar emitter mai juriya mai girma ta yi aiki.** Yatsun ƙarfe na iya matsewa sosai. A cikin takardar, tazarar ta ragu daga 1066 μm zuwa 944 μm. Yatsu masu yawa suna nufin gajeren tafiyar mai ɗaukar kaya, don haka juriya ga ƙarfin emitter sheet ya ƙaru. Ƙididdigar takardar ta nuna cewa yayin da ƙarfin emitter sheet ya haura daga 300 zuwa 600 Ω/sq, fa'idar farantin ƙarfe tana faɗaɗa daga 0.09% zuwa **0.12%**.

Wannan lamari ne na littafi game da **tsarin da ke canza taga aikin**: buga farantin ƙarfe ba kawai musanya firinta ba ne, yana buɗe sabon filin ƙirar emitter.

Game da farashi da rayuwar stencil farantin ƙarfe da kansa, ga lissafin da layin ya fi damuwa da shi:

- Al'ada PI-film ƙarfe-waya allo: **4,000-8,000 yuan kowanne**, rayuwa kusan **400,000 wafers**.
- Stencil farantin ƙarfe (matakin ƙaddamarwa na yanzu): farashin raka'a **fiye da 50% mai rahusa** fiye da PI-film (kewayon 2,000-4,000 yuan), amma rayuwa kusan **200,000 wafers** a yanzu. Mai kyau ya kai 200,000, mara kyau ana maye gurbinsa a 150,000.

Amortization na allo: PI-film kusan 0.01-0.02 yuan/wafer, farantin karfe kusan 0.01-0.02 yuan/wafer. **Suna karya daidai.** Amfanin farantin karfe ba a cikin allo ba, yana cikin **tanadin azurfa**: 3-5 mg a kowace wafer a kan yatsa na baya, kusan **0.047-0.079 yuan/wafer**, wanda ya fi girma fiye da gibin amortization.

Amma rayuwar farantin karfe rabin na PI-film ne, ma'ana **sau biyu na yawan canji, sau biyu na lokacin dakatarwa, sau biyu na aiki**. Ko tanadin azurfa ya rufe farashin ɓoye na canji mai yawa ya dogara da yadda layin ku ke cika. Ga manyan 'yan wasa masu cikakken aiki, lissafin yana aiki. Ga layukan da ba a yi amfani da su sosai ba, farantin karfe bazai biya ba. Wannan shine dalilin da ya sa Tongwei da Jietai, waɗanda ke da ƙarfin sha na cikin gida, suka yi ƙarfin zuwa gaba. **Girma yana rage raunin gajeren rayuwa.**

### Na biyu: Tuntuɓar Azurfa-Silicon, Ƙarin 0.4% Fill Factor da Buga Farantin Karfe ke Bayarwa

Ƙananan yatsu suna bayyana ƙarancin inuwa da ƙarancin azurfa. Amma buga farantin karfe yana ba da ƙarin riba: **ƙarancin tuntuɓar ya ragu kusan 15%**. Auna a cikin takardar: **2.4 mΩ·cm²**, fiye da buga allo, kai tsaye darajar **0.4% cika factor (FF) riba**.

Samfuran farantin karfe suna da **babban yawan ƙwayoyin da aka lura**, girman 20-40 nm, sun fi bazuwa daidai. TEM ya kara nuna samfuran farantin karfe sun kafa **tsari mai yawa, ci gaba da hanyar sadarwa na azurfa** a cikin gilashin a mahadar azurfa-silicon.

Waɗannan ƙwayoyin azurfa sune hanyar wutar lantarki. Electrons ba sa buƙatar ketare gilashin mai juriya; suna tsalle kai tsaye tsakanin ƙwayoyin azurfa.

Mafi kyawun shaida ya fito daga **scanning spreading resistance microscopy (SSRM)**. Wannan dabara a zahiri tana "ganin" rarraba juriya: duban yanki daga silicon zuwa azurfa grid, yankuna masu juriya mai girma suna haske, yankuna masu juriya mara ƙarfi suna duhu. Yankin canjin mu'amala na samfurin farantin karfe shine **mafi ƙunci kuma mafi duhu**, don haka juriyar mu'amala da gaske ta ragu.

**Hanyar bugawa → rarraba barbashin azurfa → juriyar mu'amala → abubuwan cika.** Kowane mataki na wannan sarkar dalili yana da goyon bayan bayanai.

LECO (Laser Enhanced Contact Optimization) ya riga ya zama ma'aunin masana'antu, ana sa ran zai rufe kusan **600 GW** na ƙarfin TOPCon. Amma ko da tare da irin wannan maganin LECO, bugun farantin karfe har yanzu ya rage juriyar tuntuɓar da wani 15% fiye da bugun allo. Wannan yana nufin **bugun farantin karfe yana da asalin ingancin mu'amala wanda LECO ba zai iya daidaita shi ba.**

### Uku: Poly-Silicon na Gida, Cire Abin da Bai Kamata Ya Kasance a Nan (Fasahar Rear Poly-Finger)

Cikakken yanki poly-silicon a bayan TOPCon takobi ne mai kaifi biyu.

Kyakkyawan gefen: ingancin passivation na musamman, ɗayan mafi balagaggun tsarin sadarwa na passivated-contact a kusa.

Mummunan gefen: **poly yana sha haske.** Sha'awarsa na parasitic a cikin infrared na kusa yana cinye hasken da ya kamata ya zama wutar lantarki. Sakamakon kai tsaye: gajeren kewayawa (Jsc) ba zai iya tashi ba, bifaciality ba zai iya hawa ba. TOPCon bifaciality yawanci yana zaune a **80%-85%**, yayin da heterojunction ya kai 90%-95%.

Tunanin takardar a bayyane: **kiyaye poly kawai inda electrode ke buƙatar sadarwa, maye gurbin sauran da AlOx/SiNx.**
