The need to reduce greenhouse gas emissions and the growing interest in renewable energy sources are well known so, the investigation of the chemistry and physics of alkali selenides and doping for thin film CIGS solar cells is the topic of this project. CIGS cells are crystalline silicon and thin film technologies based on amorphous silicon...

The present study is devoted to the experimental investigation of homogeneity range and heat of formation (ΔfH° at 300K) of the cubic L12–HfAl3-xZnx solid solution. A high-temperature direct drop calorimeter has been employed to synthesize and simultaneously determine the ΔfH° of several alloys along the HfZn3–HfAl3 section (25 at. % Hf)...
