Sekureva kwesangano renyanzvi dzefizikisi, vaongorori vekuFinland vakagadzira chishandiso che "black silicon photodetector" chine "external quantum efficiency" ye130%, inova ndiyo nguva yekutanga iyo "photovoltaic devices" ichipfuura muganho wepfungwa we100%, izvo zvinotarisirwa kuvandudza zvakanyanya mashandiro e "photoelectric detection devices", uye zvishandiso izvi zvinoshandiswa zvakanyanya mumotokari, nharembozha, mawachi akangwara uye michina yekurapa.
Photodetector i sensor inogona kuyera chiedza kana imwe simba remagetsi, kushandura maphotoni kuita magetsi, uye maphotoni anonyudzwa anoumba maerekitironi nemaburi maviri. Photodetector inosanganisira photodiode ne phototransistor, nezvimwewo. Quantum efficiency inoshandiswa kutsanangura huwandu hwemaphotoni anogamuchirwa nemudziyo wakaita se photodetector kuita maerekitironi maviri, kureva kuti, quantum efficiency yakaenzana nehuwandu hwemaerekitironi anogadzirwa ne photon akakamurwa nenhamba yemafotoni anoitika.
Kana photon incident ichiburitsa maerekitironi kuenda kudunhu rekunze, kushanda kwe quantum yekunze kwechishandiso ichi kunosvika 100% (yaimbofungidzirwa kuti ndiyo muganho wedzidziso). Mukudzidza kwazvino, black silicon photodetector yaive nekushanda kusvika 130 muzana, zvinoreva kuti photon imwe incident inogadzira maerekitironi angangoita 1.3.
Sekureva kwevaongorori veAalto University, chombo chakavanzika chiri shure kwekubudirira kukuru uku inzira yekuwanda kwemuchina wekufambisa magetsi inoitika mukati mechimiro chenano cheblack silicon photodetector, icho chinokonzereswa nemaphoton ane simba rakawanda. Kare, masayendisiti akanga asina kukwanisa kuona chiitiko ichi mumidziyo chaiyo nekuti kuvapo kwekurasikirwa kwemagetsi nemaziso kwakaderedza huwandu hwemaerekitironi akaunganidzwa. "Midziyo yedu yenanostructured haina recombination uye haina reflection loss, saka tinogona kuunganidza ese ma multiple charge carriers," akatsanangura mutungamiri wekudzidza Purofesa Hera Severn.
Kushanda zvakanaka uku kwakasimbiswa neInstitute of Physical Technology yeGerman National Metrology Society (PTB), iyo inova ndiyo nzira chaiyo uye yakavimbika yekuyera zvinhu muEurope.
Vaongorori vanoti kushanda zvakanaka kwezvinyorwa izvi kunoreva kuti masayendisiti anogona kuvandudza zvikuru mashandiro emidziyo yekuona ma photoelectric.
"Michina yedu yekucherekedza zvinhu yakonzera kufarira kukuru, kunyanya munyaya dze biotechnology nekutarisa mashandiro emaindasitiri," akadaro Dr. Mikko Juntuna, CEO weElfysInc, kambani iri pasi peAalto University. Zvinonzi vatotanga kugadzira michina yakadaro yekucherekedza zvinhu kuti ishandiswe mubhizinesi.
