摘要：

Nano-sized dispersions have been employed as precursor inks for the spray deposition of contacts to both Si and CdTe materials. In the case of Si, nano-sized Al particles (nano-Al) were dispersed and spray deposited onto p-type Si. Annealing above the eutectic temperature causes alloy formation yielding a p+ layer with p similar to 10(-4) Omega(.)cm. For CdTe, nano-sized Te particles (nano-Te) were dispersed and sprayed onto CdTe/CdS/SnO2/glass heterostructures. Contact to the CdTe layer occurred during a 30 min anneal in He (T = 215 to 255 degrees C). These solar cells were finished by spin-coating the Te layer with Ag paint and subsequently annealing in air (100 degrees C / 1 h). This approach produces solar cells with open circuit voltages (V-oc) from 720 to 800 mV, short circuit current densities (J(sc)) from 18 to 20 mA/cm(2) and efficiencies up to 10.3%. The performance of these cells was similar to those produced using the standard NREL contact.
