Débats du Parlement européen. Compte rendu in extenso des séances du 17 au 19 mai 1971. No 138. Session 1971-1972. Mai 1971. = Debates of the European Parliament. Proceedings report in full of the sessions of 17 to 19 May 1971. No. 138. Session 1971-1972. May 1971

The field of solution‐processed photovoltaic cells is currently in its second spring. The dye‐sensitized solar cell is a widely studied and longstanding candidate for future energy generation. Recently, inorganic absorber‐based devices have reached new record efficiencies, with the benefits of all‐solid‐state devices. In this rapidly changing environment, this review sheds light on recent developments in all‐solid‐state solar cells in terms of electrode architecture, alternative sensitizers, and hole‐transporting materials. These concepts are of general applicability to many next‐generation device platforms
