Transparent conductive oxide
glass back contact absorber transparent contact transparent and conductive visible infra-red
normal TCO new TCO
absorption by free electrons new TCO: less free electrons ⇒ less absorption better mobility of electrons ⇒ same conductivity ⇒ more current from the solar cell
