I-Picosecond Laser Cutting Machine inceda uPhuhliso lweeSeli zeSolar eziNcinciweyo zeFilimu

Phakathi kwazo zonke iiseli ze-solar zefilimu ezibhityileyo, i-CIGS (i-copper indium gallium selenium) iseli yelanga ineyona ndawo iphakamileyo yokufunxa i-coefficient yokukhanya okubonakalayo, kwaye ukusetyenziswa kwezinto ezikrwada kusezantsi kakhulu kuneeseli zelanga ze-crystalline ze-silicon.Xa kuthelekiswa neeseli ze-crystalline ze-silicon zelanga ezinomgangatho ophezulu kunye neendleko eziphezulu kunye ne-amorphous silicon iiseli zelanga zelanga ezinomgangatho ophantsi kunye nexabiso eliphantsi, iiseli ze-CIGS zelanga zineenzuzo ezininzi zokusebenza okuphezulu, ixabiso eliphantsi kunye nobomi obude.Yeyona ithembisayo ephezulu ithembisayo ifilimu ebhityileyo yeeseli zelanga zokunciphisa iindleko zokuvelisa amandla e-photovoltaic, kwaye inokusebenzisa ngokupheleleyo izixhobo zaseTshayina ezityebileyo ze-indium, luhlobo lobuchwepheshe obuvuselelekayo obuhambelana nenyani nezibonelelo zesizwe. imithetho kunye nemimiselo kwaye ilungele iimeko zelizwe laseTshayina, kwaye inethemba lophuhliso olubanzi.

Umatshini wokusika we-laser we-Picosecond unamandla aphezulu kakhulu ngenxa yobubanzi bawo obufutshane be-pulse, kuphela ii-piccoseconds ezimbalwa.Ifaneleke kakhulu ukukrola kunye nokubhala imathiriyeli yeseli yefilim yelanga.Xa isebenzisana nezixhobo, i-thermal effect ye-etching part incinci kakhulu, ibangela ukuba "ibanda" isebenze, igweme umphumo ongeyomfuneko we-thermal, akukho ndawo echaphazelekayo yokushisa, kunye nomda ogudileyo.Ke ngoko, i-picosecond laser ingasetyenziselwa ukuchaneka okuphezulu.Ubude belaser yepicosecond busuka kwi-infrared ukuya kwi-ultraviolet.Iyakwazi ukucubungula uluhlu olubanzi lwezixhobo kwaye ifanelekile kwizicelo ezininzi.

Ngokwembono yehlabathi, indibaniselwano yetekhnoloji yamandla elanga kunye nemimandla eyahlukeneyo inamandla.Ukusuka kwiindawo ezinexabiso eliphezulu ezifana nezakhiwo, iimoto, i-electronics abathengi ukuya kwiisathelayithi, ifilimu encinci yamandla elanga yenze uluntu lwabona ukubakho kwamandla exesha elizayo.I-laser ye-Picosecond enobuchule bayo bokusetyenzwa bugqwesileyo iya kuba nethemba eliphezulu kakhulu lentengiso kwibala lokusetyenzwa kweeseli zefilimu elanga.
